SizeGenix is another male enhancement product that is heavily marketed. This is why I have decided to have a detailed look at it and share with you the results of my analysis.
Is SizeGenix the best option you can use that will help you to get a bigger penis?
The porn stars such as Ron Jeremy or Evan Stone are endorsing this product. However, we all know that celebrity endorsement isn’t always the best way to measure the effectiveness of individual product (especially in the field of male enhancement).
That is why I bought the product, decided to analyze the ingredients of SizeGenix, shared its potential side effects, provided sources of various user feedback and many more (just see the table of contents below).
I have to say that SizeGenix is (according to my personal opinion) neither the best option on the market nor the worst one as it has many advantages as well as disadvantages. Just go over this complex review to learn why I think so.
Basic Information About SizeGenix
Company Behind This Product
This product is manufactured by a company called “INCREDIBLE HEALTH DECISIONS, LLC”. Sadly, I was not able to discover any information related to this company, just the fact that it also stands behind the competing product called Rexavar.
If you have any more information about this company please let me know in the comments section below this article. Don’t get me wrong, I am not saying that this is an unknown company that is new in the field of male enhancement.
I just wasn’t able to find any info on it.
The Way SizeGenix Works
According to the information provided on the official product website SizeGenix.com, these pills work on two main principles. Firstly, they should improve the level of free testosterone in your blood to improve your sex drive.
Secondly, these pills should increase the blood flow into your penis to improve the quality of your erections.
On a physiological level, this product works by:
- Entering your blood flow and chambers of your penis
- Releasing testosterone into the penile tissue
- Improving nitric dioxide levels to dilate blood vessels in your penis
Thanks to more blood flowing into your penis, it will reach its maximum capacity making it appear larger (especially if you were not able to reach maximal blood flow before taking SizeGenix).
From publicly available studies on various active substances included in SizeGenix, I have to say that this product seems to be very promising in treating the erectile dysfunction and improving the quality of your erections.
One thing to mention is that the creators of this product state that most of the changes will be experienced between 47 and 77 days of usage. So don’t expect immediate results.
Please, keep in mind this:
Based on my knowledge and experience in the field of permanent penis enlargement, no pills will increase your penis size on their own. Although they may speed up this process, you need to follow a complex routine that includes several penis enlargement exercises as well.
Only that way you can expect permanent gains.
Ingredients From Product Label
To assess any male enhancement pill you need to study the ingredients thoroughly. Because I am no chemical expert, I always consult reputable websites on individual substances used in any kind of product.
According to the SizeGenix product label on the bottle that I have bought, it contains the following ingredients:
- Niacin (45 mg)
- Butea Superba
- Tribulus Terrestris Extract
- L-Arginine Nitrate
- Vitis Vinifera
- Protodexx Matrix Complex
- Muira Puama
- Maca Root
- Long Jack
- Avina Sativa Extract
- Long Pepper Extract
- Magnesium stearate
- Titanium dioxide
This is a complete list of ingredients that are published on the product label I have received after making a purchase on the official product website Sizegenix.com.
Below I am providing a detailed analysis of individual ingredients.
#1. Niacin (Vitamin B3)
Niacin, also known as vitamin B3, helps men to increase blood flow into the penis by relaxing your blood vessels leading to a much better erection. The best part?
Niacin will help you to reduce fatigue as well (B vitamins do that pretty effectively).
There has been a research study (2011) conducted that analyzed and compared the efficiency of statins and niacin in improving the erectile dysfunction. The conclusion is that niacin is a good treatment:
“Niacin alone can improve the erectile function in patients suffering from moderate to severe ED [erectile dysfunction] and dyslipidemia.“
From what I have learned about niacin, it is a great addition to your supplement stack if you want to maintain a well functioning penis.
#2. Butea Superba
(Volume Not Disclosed)
The Butea Superba helps increase sexual performance and has been shown to help with erectile dysfunction. The phytoandrogens found in such a high supply within the herb mimic male hormones, which gives men faster recovery times, increased muscle tone, strength, and energy.
These statements are supported by various research studies. One has been conducted on Thai males and discovered the following:
“A 3-month randomized double-blind clinical trial was carried out in volunteers with ED [Erectile Dysfunction], aged 30 years approximately 70 years, to evaluate the therapeutic effect of the crude preparation of Butea superba tubers on ED. There was a significant upgrading in 4 of the 5 descriptive evaluations of the IIEF-5 questionnaire. Estimation of the sexual record indicated that 82.4% of the patients exhibited noticeable improvement. Haematology and blood chemistry analysis revealed no apparent change.”
Another research study published in BioMed Research International (2014) pointed out that this ingredient has a positive effect in vivo on the quality of erection:
“The ethanol extract of B. superba is effective in enhancing penile erection. The ethanol extract increased intracavernous pressure (ICP) in vivo. It also significantly enhanced the effects of cGMP and isobutylmethylxanthine. This suggests that B. superba may act through cAMP/cGMP pathways.“
Butea superba seems to be a very effective ingredient that promotes the blood flow into your penis and therefore improves the quality of your erections.
#3. Tribulus Terrestris Extract
(Volume Not Disclosed)
Tribulus terrestris is a substance that increases free testosterone levels in the body. On the sexual side of things, Tribulus does appear to be a relatively reliable and potent libido enhancer in rats.
There have been conducted few human studies but these indicate that tribulus may not be more effective than a placebo in treating erectile dysfunction:
“At the dose and interval studied, Tribulus terrestris was not more effective than placebo on improving symptoms of erectile dysfunction or serum total testosterone.”
However, scientists have confirmed the fact that tribulus has a positive impact on male fertility and the health of your sperm:
“The incubation of human semen with 40 and 50 μg/mL of T terrestris extract significantly enhanced total sperm motility, number of progressive motile spermatozoa, and curvilinear velocity over 60 to 120 minutes’ holding time (P < .05 or P < < .01). Furthermore, viability was significantly enhanced by using T terrestris extract (P < .01).”
This is great ingredient especially for those guys, who have not only low libido but also problems with conceiving a child.
#4. L-Arginine Nitrate
(Volume Not Disclosed)
The L-Arginine is utilized to create nitric oxide which dilates blood vessels and allows for improved blood flow. This ingredient also helps the body release insulin and growth hormone.
L-Arginine has been shown to improve blood flow to the genital area by dilating blood vessels and helping the penis to enlarge to its full capacity, thus increasing the size, hardness, and frequency of erections.
“30 patients (94%) completed the whole treatment schedule. Five (17%) patients reported a significant improvement in erectile function at the end of the L-arginine phase and 6 (20%) patients after the placebo period. 17 (56%) patients showed little improvement with L-arginine and 13 (43%) with placebo. In 8 patients (27%) of the verum group there was either no change in the ED score or even a slight worsening.“
As you can see in the study above, the results are quite good. Actually, there is another excellent research study that was published in BJU International (1999) that confirms its role in increasing the nitric oxide:
“Nine of 29 (31%) patients taking L-arginine and two of 17 controls reported a significant subjective improvement in sexual function. All objective variables assessed remained unchanged. All nine patients treated with L-arginine and who had subjectively improved sexual performance had had an initially low urinary NOx, and this level had doubled at the end of the study.“
The best part is that L-Arginine improves the subjective sexual functions as well.
#5. Vitis Vinifera
(Volume Not Disclosed)
According to some Ayurvedic websites such as “Ayur Help“, the Vitis Vinifera, also known as grapes, helps to increase the fertility of men and women. It increases quality and quantity of semen, sperm count, and sperm motility.
However, I was not able to find any supporting evidence in research studies. Actually, this research study observes the exact opposite in male rats:
“We found that GJ [grape juice] reduces body weight difference, was associated with decreased sperm motility and count in all treatment groups (p≤0.05 and p≤0.001, respectively). Moreover, DSP [daily sperm production] was significantly decreased in all treatment groups compared to the control group (p≤0.05), except in the group receiving 100 mg/kg of GJ. Inhibin B levels were significantly decreased in all treatment groups (p≤0.05).“
This ingredient doesn’t seem to be very effective in improving your erections or libido. On male rats, it even reduced fertility and the amount of sperm they were able to produce on daily basis.
#6. Protodexx Matrix Complex
(Volume Not Disclosed)
Sadly, I was not able to discover any detailed information on this substance. I have no idea how it relates to male sexual health. I have only read some brief info that it should promote vasodilation similarly as nitric oxide.
If you know how it works, please leave a comment at the end of this article.
(Volume Not Disclosed)
The L-citrulline is an amino acid normally made by the human body. It is then converted to L-arginine, another type of amino acid that significantly improves the blood flow by creating a nitric oxide (NO), a special gas that helps widen blood vessels.
Although the research to support the use of L-citrulline as an ED treatment is limited, it seems very promising:
“Although less effective than phosphodiesterase type-5 enzyme inhibitors, at least in the short term, L-citrulline supplementation has been proved to be safe and psychologically well accepted by patients. Its role as an alternative treatment for mild to moderate ED, particularly in patients with a psychologically fear of phosphodiesterase type-5 enzyme inhibitors, deserves further research.“
You could ingest L-Arginine directly but it is mostly metabolized by your digestive system before it can produce nitric oxide. That is why some researchers focus their attention on its precursor, L-citrulline.
#8. Muira Puama
(Volume Not Disclosed)
“Few clinical studies have so far examined the prosexual effects of Muira puama. Waynberg reported in 1994 that 60% of men with low libido have reported increased sexual desire and 50% of men with poor erection have reported improved erectile function following Muira puama administration. Another study has shown that Muira puama improved sexual desire, sexual fantasies, and the ability to achieve orgasm in 65% of women with prior sexual dysfunction.“
As you can see, there are strong indications that this substance has truly positive effects on both male as well as female sexual desire and libido. Not only that, it works well for improving the quality of erections as well.
#9. Maca Root
(Volume Not Disclosed)
Maca has been heavily marketed as being effective at improving sexual desire, and this claim is backed by research. A review from 2010 that included four randomized clinical studies with a total of 131 participants found evidence that maca improves sexual desire after at least six weeks of ingestion:
“The results of our systematic review provide limited evidence for the effectiveness of maca in the improvement of sexual function. However, the total number of trials, the total sample size, and the average methodological quality of the primary studies were too limited to draw firm conclusions. Moreover, our current knowledge of the risks of maca intake is insufficient. More rigorous studies are warranted.“
Although more research should be done on the effect of Maca root on male libido and sexual performance, I can say that this ingredient is very promising.
#10. Long Jack
(Volume Not Disclosed)
Eurycoma longifolia, also known as Long Jack, is reputed as an aphrodisiac and remedy for decreased male libido. What is more, there are claims that it can even boost testosterone levels in men.
However, this has been shown to work only among men with very low concentrations of testosterone, it doesn’t work if you have normal levels of this hormone.
Not only that, this substance can improve the quality of your sperm and semen according to a research study published in Asian Journal of Andrology (2010):
“Follow-up semen analyses in these patients showed significant improvement in all semen parameters. The proprietary extract of Eurycoma longifolia Jack significantly improved the sperm quality in these patients, allowing for 11 (14.7%) spontaneous pregnancies.“
There are many research studies that confirm the positive effect of Long Jack on the sexual desire and libido. This substance is quite potent.
#11. Avina Sativa Extract
(Volume Not Disclosed)
The Avina Sativa is a fancy name for a regular oat bran. There are some suggestions that oats can have positive impact on your free testosterone levels.
Actually, it should be able to free up bound testosterone in your organism, enabling it to be used more efficiently. This should lead to improved libido and sexual performance.
Sadly, I was not able to find any supporting research study conducted on either humans or animals.
#12. Long Pepper Extract
(Volume Not Disclosed)
Indian long pepper, also known as Pippali, is sometimes used in combination with other herbs in Ayurvedic medicine. Some women use it (not only) to treat the loss of interest in sexual activity.
The long pepper contains a chemical called piperine – a well known thermogenic that can promote sex drive as well. Actually, this effect was confirmed by a research study published in Research Journal of Medicinal Plant (2015):
“The results revealed that compared with control group, male mice fed on aqueous as well as ethanol extract of black pepper significantly showed a shorter courtship latency (p<0.05). On the other hand, there was no difference in the mounting frequency between treated groups. Interestingly, the mounting frequency showed a strong negative correlation with the courtship latency (r = -0.968). In conclusion, the fruit extract of black pepper potentially affect sexual drive in male mice.“
Although I was not able to discover any information between piperine and penis enlargement, it obviously can improve your sex drive and quality of your erections.
Although SizeGenix will provide you with a very potent formula, the product label will only give you the volume for a proprietary blend and not for individual ingredients used in it. I love complete transparency, and SizeGenix did not meet my criteria in this point.
Potential Side Effects
Usually, manufacturers state that their products are great and without any side effects. As you can see in paragraphs above, many ingredients in SizeGenix pills are natural and improve penis health as well as firmness and size of erections.
However, what does a reputable website, such assay about these (last checked July 25, 2017)?
- Niacin (vitamin B3) – This substance might cause burning, tingling, itching, and redness of the face, arms, and chest, as well as headaches, stomach upset, intestinal gas, dizziness, pain in the mouth, and other problems (LIKELY SAFE – see more here)
- Butea Superba – This ingredient is new and there isn’t enough information to know what the possible side effects might be (UNKNOWN – see more here)
- Tribulus Terrestris – This extract might make prostate conditions such as benign prostate hypertrophy (BPH) or prostate cancer worse, and decrease blood sugar levels (POSSIBLY SAFE – see more here)
- L-Arginine Nitrate – L-Arginine can cause some side effects such as abdominal pain, bloating, diarrhea, gout, blood abnormalities, allergies, airway inflammation, worsening of asthma, and low blood pressure (POSSIBLY SAFE – see more here)
- Vitis Vinifera – It might cause diarrhea, stomach upset, indigestion, nausea, vomiting, cough, dry mouth, sore throat, infections, headache, and muscular problems (LIKELY SAFE – see more here)
- Protodexx Matrix Complex – This one is not even listed by the WebMD.com
- L-Citrulline – This one is rather new and there isn’t enough information to know what the possible side effects might be (POSSIBLY SAFE – see more here)
- Muira Puama – Muira is rather new and there isn’t enough information to know what the possible side effects might be (UNKNOWN – see more here)
- Maca Root – Maca might act like estrogen and maca seems to be well tolerated by most people (LIKELY SAFE – see more here)
- There are no side-effects for Long Jack (Eurycoma Longifolia) listed by WebMD.com (POSSIBLY SAFE – see more here)
- Avena Sativa extract (oat bran) can cause intestinal gas and bloating (LIKELY SAFE – see more here)
- Long Pepper – This extract is rather new and there isn’t enough information to know what the possible side effects might be (UNKNOWN – see more here)
Because makers of SizeGenix declare that they use all-natural ingredients, the company itself lists no negative effects of using this formula. The only side effect, when properly dosing, can result from having an allergic reaction to any ingredient used.
SizeGenix Results & Testimonials
While doing my research on SizeGenix pills I have found various testimonials and user feedback. However, before I am going to present it to you, you need to realize that all these claims are collected from other websites.
Therefore, I can’t ensure their validity. Please take these with a grain of salt.
Testimonials From Product Website
The official product website provides a section full of testimonials. Also, there are some porn stars such as Evan Stone, Tommy Gun, and Rocco Siffredi who endorse this product.
Just have a look at this selection:
“Guys this stuff will make you bigger and make sex better. My erections are larger, longer, fuller and more powerful – no question. Great stuff…”
User feedback from Greg taken from Sizegenix.com (last seen October 3, 2018)
“I have to tell you I was skeptical that this would work, but now I’m a believer. It seemed hard to believe but I was blown away that it made me feel better, sex was better and over time I really did get bigger. About 2 inches longer and its wider too. I’m going to keep taking it at a half dose every day for as long as it still feels good. Love this stuff!”
User feedback from Larry taken from Sizegenix.com (last seen October 3, 2018)
Before & After Pictures
I have been looking all over the internet but I was not able to discover any before and after images. I assume that there must be a good reason why there are no such images with size gains.
Sure, maybe guys are too shy to publicly post images with their penises, but it could also indicate that claims made by the producing company are too bold.
Customer Reviews From Amazon
“I don’t know that it actually made a size difference but it’s only been a month so far. Definitely increased stamina and sex drive though. Good product overall.”
User feedback from Amanda T. left on Amazon.com (last seen October 3, 2018)
“Well I thought for sure this product would work after reading so many positive stories. This product didn’t measure up and I would not purchase it again. Doesn’t work !!”
User feedback from alejandro lugo left on Amazon.com (last seen October 3, 2018)
“It’s OK didn’t grow or notice anything different. It’s not worth 40 bucks.”
User feedback from Jay money left on Amazon.com (last seen October 3, 2018)
“Do not expect rapid growth you will not get larger just feel at full potential the chubb is impressive none the less.”
User feedback from marshall miller left on Amazon.com (last seen October 3, 2018)
As you can see, not all feedback is just positive. Therefore, be prepared that SizeGenix may give various results to its users. That is why I recommend purchasing a smaller supply of pills at first to see whether it works well for you or not.
The Best Place To Get These Pills
Right now, the safest place to get your supply of SizeGenix pills is from the official product website called SizeGenix.com. I would not dare to buy this product from anywhere else as there are many fake versions of this product being sold all over the internet.
Also, there are several other advantages to making a purchase on this website, such as discreet shipping and billing, fast delivery, and more. Here is a screenshot of the official product site:
Official Price & Offers
At the time of writing my review, I was able to order a single SizeGenix bottle for $39.95 (or €34.56). They do offer extra deals if you purchase more bottles at once:
- 2+1 Free – For 3 bottles you will pay only $79.95 (around €69.19). That is just $26.65 for a bottle (around €23.03).
- 3+2 Free – For 5 bottles you will pay only $119.95 (around €103.80). That is just $23.99 for a bottle (around €20.76).
- 4+3 Free – For 7 bottles you will pay only $159.95 (around €138.42). That is just $22.85 for a bottle (around €19.77).
Also, don’t forget to add a flat shipping cost of $19.95 (around €17.26) depending on your location.
Shipping & Billing Policies
With regards to the privacy of your purchase, you will get your supply of pills in a plain brown package. Just see for yourself what they say about it (quote was taken from official FAQ page):
“SizeGenix® is shipped in a plain padded envelope and no one but you will know what’s inside your package.“
“We ship Monday through Friday and always ship within 24 hours upon receipt of your order. Shipping takes between 2 and 7 business days (within the USA).”
I have made my purchase on the official product website and I have to admit that the billing and shipping were discreet. As you can see in the image below, my package came in a brown envelope, that didn’t indicate in any way what was hidden in it:
As you can see in the image above, it was sent to me from USA (Los Angeles, California) and it included no mention of SizeGenix on it.
Money Back Guarantee
The best part of making your purchase on the official product website is that you are offered an excellent, 90-day money back guarantee. This is a quote from their official FAQ page:
“We don’t just offer a money-back guarantee – we offer the strongest, most honored money back guarantee in the entire industry. Simply put – if you are not 100% thrilled with the amazing results you get with SizeGenix® you can get a complete 100% refund within 90 days of purchase – no tricks, not games, no complicated forms, no tomfoolery like other companies.“
I have to say that these conditions for a money back guarantee in a market for male enhancement pills are more than fair and customer-friendly.
SizeGenix vs Male Extra
Comparison Of Ingredients
The SizeGenix website only provides you with the most active substances they use in their formula. However, the precise numbers for each individual substance used in their patented proprietary blend are missing even on the product label.
The official website of Male Extra is very open with regards to ingredients used. There are publicly shared precise numbers of each substance used not only online but also on the product label.
With regards to ingredients, I have to point out that each company provides several potent ingredients in their formula. However, the company behind Male Extra is much more transparent and reliable as they provide precise numbers of each substance used.
Comparison Of Dosage Directions
With SizeGenix pills, all you have to take are just 2 pills on an empty stomach (preferably in the morning), once a day. The Male Extra brand states that you need to take 3 pills daily, preferably after your meal.
Pills, especially those taken in the morning on an empty stomach, can be hard to digest if you have frequent issues with upset stomach as I do. Although it may seem that SizeGenix has better dosage (you take one pill less), I do not like the fact that you should take this supplement on an empty stomach.
Comparison Of Guarantees
SizeGenix provides an excellent 90-day money back guarantee. All you need to do is to call their customer service for a mailing address and send them the rest of your product for a 100% refund.
Male Extra provides solid 60-day money back guarantee. All you need to do is to send them an email for return instructions. Then, you need to send them back your unused pills in the original container and they will refund you 100% purchase price excluding the return shipping costs you paid.
As you can see, SizeGenix has a much longer period during which you can return your unused product back for a refund.
Comparison Of Prices & Shipping
One month supply of SizeGenix (single bottle – 60 pills) will cost you $39.95 while one month supply of Male Extra (single bottle – 90 pills) will cost you $64.95 (almost twice as much).
With regards to shipping policies, SizeGenix sends these pills internationally and you will need to pay $19.95 (a flat shipping rate). On the other hand, Male Extra offers free worldwide shipping.
Although the SizeGenix seems to be cheaper on the first look, when you add the shipping rate to the product price, both these products cost almost the same. Male Extra is also available in more countries than SizeGenix.
Final Verdict On SizeGenix
Is this the best supplement for penis enlargement? To sum up this review, I have to say that SizeGenix seems to be working quite good for improving the blood flow in your penis and the quality of your erections.
However, I do not see anything in its formula that should permanently improve the maximal size of your penis.
Besides that, I have to admit that this product has its pros:
- Utilizes potent ingredients
- Improves your sex drive and blood flow
- Less expensive than competing products
- Solid money back guarantee
- Provides research studies on some ingredients
Sadly, there are also some negative aspects of SizeGenix, including:
- Not a completely transparent formula
- Takes time to see the results
- It is pricey
- You should take it on an empty stomach
- Some negative comments on Amazon
I have no doubts that SizeGenix is much better than many other competing products. However, I can’t say that it is the best option out there. If you want to get your supply from a reputable place, visit SizeGenix.com.
Just keep in mind that for permanent and gradual penis enlargement, you need to combine pills improving your blood flow with the traction and tension applied to the shaft of your penis (thanks to exercises, pumps, and extenders).
Frequently Asked Questions (FAQ)
I have tried my best to create the most comprehensive guide on SizeGenix pills. However, if you still have a question on your mind, then browse through my FAQ section below.
Is SizeGenix Safe?
I am no medical expert but I can say that as long as you are healthy, you can consider SizeGenix pills to be safe. Because makers of SizeGenix declare that they use all-natural ingredients, the company itself lists no negative effects of using this formula.
The only side effect, when properly dosing, can result from having an allergic reaction to any ingredient used.
How To Use SizeGenix?
There are 60 pills in each bottle. You’re required to take two pills a day on an empty stomach. Ideally, drink one 8 oz glass of water.
You shouldn’t use this product if you are at the risk of or being treated for high blood pressure, kidney, liver, thyroid or psychiatric disease, anxiety or if you suffer from depression.
Dosage info was taken from a product label (October 19th, 2018). Please always check and follow dosage rules on your product label as these may have changed over time.
How Long Does It Take To Work?
Although I have bought this product, I have never used it on myself. That is why I can’t say properly if these pills really work or how long it take to achieve results.
I have only a quote taken from the official website on 22nd October (2018), that deals with this issue:
“However, over 94% of men who use SizeGenix® experience a substantial increase in the size of their penis, but the rate of time varies from man to man, but generally 47-77 days is the most common time zone for significant size change. SizeGenix® will continue to work the longer you use it.”
As you can see, the official statement is to expect the most significant changes after using these pills for 2-3 months.
Is SizeGenix Permanent?
This is another question that is hard to answer without using this product. However, I have found statements that say that your size gains should be permanent.
Sadly, if you decide to take these pills to improve your erection issues, then you will need to take it until you fix the real cause of your problems.
Is Free Trial Offer Available?
At the time of writing and updating this review, I was not able to find any free trial offer on the official product website SizeGenix.com. However, this may have changed in the meantime so don’t forget to check it out.
Is SizeGenix Available On GNC?
I have been looking all over the GNC.com but I was not able to find any SizeGenix offer.
Is SizeGenix Available On Amazon?
What Color Is SizeGenix Pill?
As you can see in the image above, the SizeGenix container I have bought included 60 white capsules. These seem to be easy to swallow.
How Can I Boost The Results Of SizeGenix?
If you want to improve your penis enlargement efforts and permanent size gains, then you need to focus on these penis enlargement exercises. Also, you could try to use a scientifically confirmed device called penis extender (here are the best brands on the market).
If you are looking for huge gains that are temporary, then consider investing your money into a hydro-based penis pump, such as Penomet or Bathmate. Over time, these temporary gains can transform into permanent ones.
