Shortened Review

I would recommend the SizeGenetics device if you’re interested in increasing your penis size. Wearing it throughout the day is easy and comfortable. Although the price is slightly above the average, I believe that the extra comfort levels are worth it. Also, if it doesn’t work for you, then you can always get your money back.

In Depth Review

Over the last 6 months, I’ve been testing out the SizeGenetics penis extender and it’s finally come time to share my experience.

In this review, I’ll include everything you need to know to make a well-informed decision about whether or not you should buy this device.

My Story

For years, I had been dissatisfied with the size of my penis.

I was humiliated as a teenager on countless occasions and my confidence was shot so much I didn’t even attempt to have sex for years.

Eventually, when I did muster up the courage to bring a girl back to my place…

The shock on her face as I undressed still burns in my mind.

I remember the fake moans as I penetrated her; trying to cover up her discontent.

That night, I never felt so inadequate in my life.

It was at that moment I realised something had to change.

I decided to start researching penis enlargement.

After scouring the internet, I quickly realised that it was full of scams.

How do I know this? Admittedly, I fell for all of them.

I wasted hundreds on penis pills and pumps with zero results!

The other option was penile surgery.

However, with the costs running into the thousands and the potential loss of sensitivity in my penis, it was simply not worth the risk.

I had almost come to terms with the fact that my size was never going to change.

Then one day, I read about someone’s experience with penis extenders and ,instantly, I was back in the game, filled with hope.

This time though, I decided not just to just make an impulse buy, but instead to make sure the products I buy are guaranteed to work.

I discovered that penis stretching devices, like the SizeGenetics model, were the only way that had been clinically proven to increase your penis size.

During my research, I found a study from 2009 where they got a group of men to wear penis extenders for 6 months and record the difference in their size.

Shockingly, the average size increase was an 2.3cm - almost an inch!

My first thought was…

If I were to increase my size by that much, I’d be on par with the US average!

The average penis size in the United States is 5.1 inches by the way.

And, with this study being 10 years old now, the devices they used must have been primitive compared to what’s available now.

Searching online for the best penis extenders, I noticed time and again that SizeGenetics kept coming up top of the list.

With the knowledge that many product reviewers had favoured this device, I was even more excited at the prospect of impressing the ladies with a bigger sized dick.

Before I got carried away, I collected my thoughts and considered that these reviewers were only a small sample of the number of people who used the device.

I looked for feedback received from real customers and the results were just as positive. I must of spent several hours pouring over those many reviews looking fo potential flaws.

When I saw that SizeGenetics offered a double-money back guarantee if it doesn’t work, I was sold.

I had nothing to lose and everything to gain.

By the way, when I bought, they were doing a 40% discount on their normal prices. I believe it’s still valid. Just click here’s the link if you want to check.

Delivery & Unboxing

One of my biggest reservations in buying any penis extender was that it could lead to some embarrassing situations if it got into the wrong hands.

I was particularly aware of this because my neighbour (who I’m actually attracted to) usually collects my parcels for me.

I was re-assured by the sales rep at SizeGenetics that all packages are extremely discreet and, true to their word, it was.

When it was delivered, she was none the wiser.

Assembling The Device

Another worry of mine was that I may need to spent lots of time putting the device together.

I’ve never been much of a tinkerer so was glad to discover that it was largely pre-assembled and the only thing I needed to do was attach two parts together it was ready to go.

Just for reference, there were 5 key parts in total:

  1. A plastic ring that fits around the base of your penis
  2. Two metal bars that attach to the plastic ring with thumb screws that can change the traction levels
  3. A plastic support that slots into the metal bars
  4. The strap to keep your penis in place
  5. A comforter to place between your penis and the strap

The device also comes with extra metal bars that you can easily screw on allowing you to adjust to the size.

According to the SizeGenetic instructions, you want to have the bars extend about 1cm longer than the size of your flaccid penis to make sure there is enough traction.

Here’s what it looks like fully assembled:

How The SizeGenetics Penis Extender Works:

I wasn’t sure how penis extenders worked, but as I went through their manual it became much clearer.

The device works on a traction system. This basically means it applies a consistent stretch to you penis and over time, it increases in size, much like an elastic band,

You can apply different levels of traction to the the springs inside the metal bars and it will apply more or less of a stretch.

Obviously, the more stretch you apply, the quicker it will increase your size.

However, there’s a caveat.

You can’t just go straight to the full intensity. It’s important to ease yourself into it.

In the same way that you wouldn’t lift the heaviest weight in the gym as a beginner, you don’t won’t to overdo your penis stretching.

Reason being that it will be uncomfortable.

Instead, it’s best to ease yourself into it.

I’ll go over the system I used later.

How To Use Your Device

Step 1:

Fasten the the plastic ring to the base of your penis (make sure that the metal bars are already attached as it can be awkward adding them on in a strange position).

Step 2:

Make sure the metal bars are running parallel with the shaft of your penis then slot them into the plastic support.

Note: you can add more bars if you need more size

Step 3:

Add the comforter around the head of your penis then fasten it in by feeding the strap through the wholes of the plastic support.

Here’s a video from the SizeGenetics official DVD showing exactly how to use it:

My Results After 6 Months

Over the course of 6 months use of SizeGenetics, I was able to increase my penis size from 4.1 inches to 5.3 inches, beating the national average.

Here’s the timeline so you can get an idea of what to expect:

Month 14.1 inches
Month 24.2 inches
Month 34.5 inches
Month 44.7 inches
Month 55 inches
Month 65.3 inches

The Programme I Used To Get Results

From what I’ve read online, some guys come up with their own penis extender routines to fit their schedule and get faster results.

However, to be on the safe-side, I just followed the official programme that comes with it.

Here it is:

Week 1:

2-3 hours use per day with traction levels 600-900g

Week 2:

3-4 hours use per day with traction levels 600-900g

Week 3:

4-5 hours use per day with traction levels 600-900g

Week 4:

4-6 hours use per day with traction levels 600-900g

Week 5:

6-7 hours use per day with traction levels 600-900g

Week 6:

7-8 hours use per day with traction levels 600-900g

Week 7 and onwards:

8-12 hours use per day with traction levels 900-1200g


Every 2 hours, you want to remove the device and massage your penis to circulate the blood flow.

How It Has Affected My Life

It’s strange to think that just by increasing the size of your penis, it can affect so many other areas of life too.

What I noticed more than anything was a boost in confidence. I felt less shy talking to women I found attractive. I was no Casanova, but it was a huge difference compared to the awkward mess I was before.

The other night, I was out in a bar with my friends and a woman started talking to me. Before, I would have frozen up, worrying that if we did end up having sex, she would later on be disappointed or laugh.

In that moment though, I was completely in the moment. Yes, she was laughing, but this time, at my jokes. I got her number and we ended up having incredible sex the following week. I could actually feel her orgasms!

To me, having a bigger sized penis was more about feeling a greater sense of self-worth than anything else.


I would absolutely recommend the SizeGenetics device fo anyone looking to increase the size of their penis and boost their confidence. It worked exceedingly well for me and I plan to continue using it to achieve even greater gains.
