When you want a bigger penis, you have four options available: extenders, hydro-based pumps, manual exercises, and pills. The best approach is to combine all four of these. However, the right supplement can make a real difference in your efforts.

Make sure you read this in case you have small penis:

The question is: Is SizeGenix the best option you can use that will help you to get bigger? You can read all about the best products for men in 2017 via this comprehensive guide: Top 5 Male Enhancement Pills on the Market

The porn stars such as Ron Jeremy and Jenna Jameson will tell you: yes. However, we all know that celebrity endorsement is not always the best way to measure the effectiveness of individual products.

Therefore, I am going to provide you with my personal opinion on this product, provide you with different user feedback I was able to discover on the internet and a comparison to other male enhancement brands I know are good.

The Way This Supplement Should Work

sizegenix bottle

Specially formulated, the real magic behind SizeGenix is in the ingredients (more on that soon). But on a scientific level, this product works by:

  • Entering the chamber of the penis.
  • Releasing testosterone into the two penile chambers.
  • Saturating the penis tissue.

What this does is cause the capillaries in the penis to expand along with the chambers. As this process occurs, you’ll notice that your buddy has now grown.

The creators of this product state that most of the changes will be experienced between 47 and 77 days of usage. So do not expect immediate results.

Pay attention: This formula is in the process of being patented in the USA.

List of Ingredients & Side Effects

What ingredients are in this product? Well, its main power lies in just six substances (first six on this list, there are more however). These (I encourage you to look them up yourself), include:

  1. Butea Superba – Helps increase performance and has been shown to help with erectile dysfunction. The phytoandrogens found in such high supply within the herb mimic male hormones, which gives men faster recovery times, increased muscle tone, strength, and energy. (Read more here)
  2. Tongkat Ali 200:1 Extract – An ingredient to boost sexual desire and performance. The root contains compounds that have repeatedly been shown in animal studies to stimulate libido, promote semen quality, and even support muscle growth. These effects have largely been attributed to increases in testosterone. (Read more here)
  3. Tribulus Terrestris Extract – 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 and the lone human study assessing this has confirmed an increase in sexual well being and erectile function. (Read more here)
  4. L-Carnitine Known to boost sexual ability, this ingredient also helps alleviate fatigue while promoting circulation. Preliminary studies suggest propionyl-L-carnitine may help improve male sexual function. One study found that carnitine improved the effectiveness of sildenafil (Viagra) in men with diabetes who had not previously responded to Viagra. In another study, a combination of propionyl-L-carnitine and acetyl-L-carnitine improved the effectiveness of Viagra in men who had erectile dysfunction after prostate surgery. (Read more here)
  5. Long Pepper Extract Helps to increase free testosterone levels in the body.
  6. L-Arginine Nitrate – Utilized to create nitric oxide, which enhances 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. (Read more here)
  7. Avena Sativa Extract – Its stimulating effects are well known in the animal world, especially with horses where it is widely known that if you feed them oats their behaviour will be wild and energetic! (Read more here)
  8. Maca Root – 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. (Read more here)
  9. Muira Puama
  10. Niacin (Vitamin B3)

Other ingredients include gelatin, vegetable cellulose, and vegetable magnesium stearate.

WARNING: The official company states just the amount of their proprietary blend and not the amount of individual substances used in it.

Pay attention: Because makers of SizeGenix declare that they use all-natural ingredients, the company itself lists no negative aspects of using this formula. The only side effect, when properly dosing, will be the potential to have an allergic reaction to one of the ingredients.

The SizeGenix vs. Male Extra

SizeGenix versus Male Extra


The SizeGenix website only provides you with the most active substances they use in their formula. However, the precise numbers for each individual substance in their patented proprietary blend are missing.

– The official website of Male Extra is very open with regards to ingredients used. There are precise numbers of each substance used.

With regards to ingredients, I have to point out that Male Extra company is much more transparent and reliable as they provide precise numbers of each substance used.

– The SizeGenix company officially claims that you can see the biggest size change (around 31% – 38%) in the period of 47-77 days. The other claims include firmer, longer erections; better sexual stamina; better sex drive.

The Male Extra company states that you will gain between 0.8 – 2.6 inches to your erection size in the period of 3 – 6 months. The other claims include much firmer and longer-lasting erections, better sexual stamina and libido.

I am dealing with the issue of penis enlargement for a very long time, and I trust more the Male Extra brand simply because the SizeGenix claims are too good to be true. I know that permanent size growth is a very slow and gradual process, gaining between 31-38% of your erection size in less than 2 months by just taking pills looks fishy to me. However, I may be wrong.

P.S. I have checked Amazon customer responses for SizeGenix that are labeled as “verified purchase” and they are very negative.


With SizeGenix pills, all you have to take are just two pills on an empty stomach (preferably in the morning) once a day.

– The Male Extra brand states that you need to take three pills daily, preferably after your meal.

Although it may seem that SizeGenix has better dosage (you take one pill less), I do not like that you should take this supplements on an empty stomach as doing this will always upset it in my case.

Guarantee & Price:

– The one month supply of SizeGenix will cost you $39.95 and comes with 90-day money back guarantee.

– On the other hand, for a supply of Male Extra that will last you one month, you will pay $64.95 and comes with just 60-day money back guarantee.

As you can see, with regards to guarantee and how much you will pay, the SizeGenix brand is a clear winner.

Pay Attention: I highly recommend you to check out my personal review of Male Extra brand as well.

Final Verdict: Affordable Product with Questionable Results

SizeGenix last offer imageSo is this the best supplement for penis enlargement? Well, my answer is rather complicated. Neither can I say it is the worst option on the market, nor I can recommend it as the best.

It has its pros as well as cons.

Although all of the ingredients used are natural – a major bonus – the official company does not declare precise numbers of individual substances used in their proprietary blend (at the time of writing this review).

This is always a huge warning flag for me.

Because I know that permanent penis enlargement is a slow and steady process, their claims for incredible 31-38% increase of erection size in just 47-77 days looks suspicious for me.

Therefore, I can not fully recommend this product, especially when there are other better options on the market such as Male Extra.
