SizeGenetics Review: The Bottom Line

SizeGenetics claims to be the best male enhancement product on the market. Not to mention, one of the only FDA approved and evidence-backed penis enlargement devices you can buy. Used for just a few hours per day, SizeGenetics has the potential to permanently increased the erect length of the penis and boosted your sex life like never before.



The question being – is all of the above too much to ask of an affordable penis stretcher? Or could it be that the SizeGenetics device is the device to increase the size of your penis and give you the confidence boost you’ve been looking for?

All important questions I’ll by covering in this SizeGenetics review, based on the latest SizeGenetics System for 2020.

What is SizeGenetics?



While the SizeGenetics device is (by definition) a penis extender, it’s said to be unlike any other penile traction device on the market. Both in terms of its approach and its effectiveness, the Size Genetics extender has consistently outperformed pretty much every comparable product brought to market to date.

The official SizeGenetics blurb goes beyond the usual BS claims to include formal recommendations from medical professionals and real-life users alike. SizeGenetics is one of the only devices of its kind to have received the backing of doctors and male sexual health experts worldwide – it’s also fully FDA approved.

Though SizeGenetics is designed to gradually stretch the penis as you wear the device on a day to day basis, it’s said to be unlike anything else available in terms of comfort, safety, practicality, discretion, confidence, and effectiveness.

What is SizeGenetics For?

If you’re not exactly thrilled with the size of your penis, you’re in good company. One recent study from Australia found that approximately one in every three men worldwide is unhappy with either the length or the girth of their penis. Just as a similar study carried out in the UK found that a full 45% of men would appreciate a bigger penis if the option was available.

Whichever way you look at it, this equates to almost half of all men wishing they had a bigger penis. Once again, therefore, you’re not in the minority if you’re reading this SizeGenetics review right now. Personally, I’m in the latter of these two camps. It’s not like I’m mortally ashamed of the size of my member, but hey, who wouldn’t be happy with a couple more inches? Or even a couple more centimeters? Deny it all you like, but there’s a direct correlation between penis size and self-esteem.

If you want a healthy sex life and a happy social life in general, you need confidence in your manhood – it really is as simple as that. All of which is where SizeGenetics comes into the equation – apparently, the device to give you the confidence you need.

I must’ve read at least a hundred SizeGenetics reviews to date – most of which were pretty generic and based on third-party reports. That’s why I decided that for my SizeGenetics extender review, I’d approach things from a slightly different angle. Roughly translated – I went ahead and tried SizeGenetics for myself. Hence, this is one of the few real SizeGenetics reviews where the reviewer actually used the thing! As for what happened, keep reading, and I’ll happily share my experience.

How does SizeGenetics Work?



In a nutshell, SizeGenetics works by stretching your penis over time in a gradual and controlled way. Ultimately building towards improved penis size, with or without an erection.

The science behind SizeGenetics is actually quite simple, which follows the same basic principles as an everyday workout. When you hit the weights at the gym, the exertion causes tiny ruptures and tears in the tissues of the muscles, which the body then automatically repairs. But as the body goes about these repairs, it strengthens and increases the physical size of these muscles and the surrounding tissues. Precisely why working out on a regular basis leads to visibly larger and stronger muscles.

Essentially, SizeGenetics is an effective everyday workout tool for your penis. The device has been designed to gently stretch the penis in a way that results in similar microscopic tissue ruptures, resulting in bigger and stronger tissues as the natural restoration process takes place. Given enough time, the penis grows in length, girth and strength – exactly as would be the case when working on any other muscles in the gym.

How to Assemble SizeGenetics

Each of the kits available (at different price points) comes with its own unique setup of SizeGenetics parts, which might look a little foreboding at first. Tension springs, Velcro straps, protection pads – a fair few bits and pieces to familiarise yourself with.

How to Use SizeGenetics

Wearing the SizeGenetics on the right traction setting and for the right amount of time each day holds the key to getting the best possible results. It’s worth remembering at this stage that every device ships complete with an impressive 270-day money-back guarantee.

This being the optimum amount of time needed to see and feel a real difference, with the promise of a full refund if you’re not totally satisfied.

Starting out gradually is the way to go, which begins by using the helpful video tutorial (as mentioned above) to learn how to fit and adjust your SizeGenetics. After which, it’s simply a case of easing yourself into the whole experience, following a few basic guidelines as outlined by the manufacturer:

SizeGenetics – how to use the device for the first time:

Week One – Use the device for a maximum of 2 to 3 hours per day at 600g to 900g traction.

Week Two – Increase use of the device to 4 hours per day using the same traction setting.

Week Three – Use the device for a maximum of for 4 to 5 hours per day, increasing the traction setting slightly, though to no more than 900g.

Week Four – Increase usage to a maximum of 5 or 6 hours per day, without altering the traction level.

Week Five – Increase usage time again to a maximum of 7 hours per day, at the same traction setting.

Week Six – Use the device for up to 8 hours per day at the same traction setting.

Week Seven – From this point onwards, you can adjust the traction up to 1,200g as required and where the device for up to 12 hours per day.

According to the manufacturer, it is inadvisable to wear the SizeGenetics penis extender device for more than two hours without taking a break. This is to encourage healthy blood flow and will build towards the best possible results.

Ideally, the SizeGenetics should be worn for 10 hours and 30 minutes max each day, though the upper-limit recommendation published by the manufacturer is 12 hours.

How to Wear SizeGenetics?



Positioning the SizeGenetics extender in place and achieving the ideal tension couldn’t be really easier. It’s simply a case of placing your penis in the base top of the device, after which the back protection ring can be closed, and the extension arms can be moved to the appropriate position.

The tension ring then fits comfortably under the head of the penis, ensuring the perfect amount of tension is exerted on the penis while wearing the device.

It’s a seriously easy process that’s tricky to picture without actually having gone through it yourself. Precisely why I strongly recommend checking out the video tutorial on the official SizeGenetics website, which guides newcomers through the process step by step.

How Long to Wear SizeGenetics?

The fact that the manufacturer covers the SizeGenetics device with a 270-day satisfaction guarantee suggests that this is the point by which you should see optimum results. In addition, clinical trials have shown that by following the appropriate SizeGenetics routine for six months, it’s possible to boost both the length and the girth of the penis buy anything from 8% to 30%.

As outlined in the previous section, it’s important to start out slowly and gradually increase your use of the device of time. Exact extender hours per inch are difficult to define, given how the physiology of each and every user is completely unique. This is precisely why some users experience quicker results than others, though the overwhelming majority of men who use SizeGenetics report noticeable improvements within a matter of weeks.

Hence, you should technically be seeing a difference within four to six weeks, though we should give it the full six months to see what SizeGenetics is really capable of.

The manufacturer suggests an optimum daily wear time of 10.5 hours, though this isn’t always practical or possible. Wearing SizeGenetics for shorter periods each day won’t impact its overall effectiveness – it’ll simply take longer to get the job done.

How to Make SizeGenetics More Comfortable

SizeGenetics features a 16-Way Comfort Tech System and can be adjusted in more ways than any comparable male enhancement product on the market. The manufacturer also offers a variety of additional extras for an even more comfortable experience, such as Revita Cream moisturizer, TractionPLUS Powder, and many more besides.



Using SizeGenetics without hurting your member is as simple as making the necessary adjustments to the 16-Way Comfort System. A unique take on safe and comfortable penis enhancement that incorporates the following key components, among others:

Silicon Noose

Silicon Comfort Strap

Foam Rubber Protection Pad

Fabric Covered Latex Head Grip

Non-Slip Protech Matt Slip

Each of these components has been crafted with a comprehensively comfortable and pain-free experience in mind. When getting started with the SizeGenetics device, you simply have to experiment with all the different settings available until you find the perfect configuration.

Which again is surprisingly easy – the video tutorial is covering literally everything you need to know.

Sleeping with SizeGenetics

Is sleeping with SizeGenetics in place possible? In a technical sense, the answer is yes – though doing so is not recommended.

For one thing, most people feel uncomfortable using SizeGenetics while sleeping, making it hard to get to sleep and potentially painful when you wake up. In addition, the manufacturer specifically states that you should never use the SizeGenetics device for more than 2 hours without taking a short break to encourage healthy blood flow.

As a result, sleeping with SizeGenetics is not recommended, as doing so could do more harm than good. If you’re feeling sleepy and wearing SizeGenetics at the time, the advice is to take it off before you doze off!

My Experience with SizeGenetics



Having used SizeGenetics for me, I can personally vouch for all its wild claims to fame. This thing is the real deal – it delivers on its promises and seriously exceeded my expectations.

The long and short of it (pun intended) being that over the course of around 11 months, I achieved erect penis length gains of around 1.5-inches, That might not sound huge, but it actually makes more of a difference than you’d believe.

When I picked up the SizeGenetics device in summer 2019, I measured in at around 6.1-inches erect. Not bad, but I wanted more, and that’s what I got exactly. I’m now closer to the 7.5-inch mark when hard, meaning gains of 1.5-inches or 25%. I’ve also gained girth, but to be honest, this was never my concern, so I didn’t measure circumference before getting started. I’d guess gains of about 1cm in that department, but that’s just an estimate.

Importantly, I found the entire experience with SizeGenetics experience easy, comfortable, and in no way inconvenient. You genuinely forget it’s even there once you’ve been wearing it for a few days, shy of the fact that tight pants are out of the question for a while!

So, while it’s true to say that SizeGenetics isn’t capable of performing miracles (and nor does it claim to), what it offers in terms of genuine gains is superb. It’s basically spend $300 on this thing or $30,000 on painful and dangerous surgery – no real comparison, if you ask me!
