SizeGenetics Overview

As you might have guessed, one of the most frequently asked questions we get is “How can I get a bigger penis?” Guys want it for all different reasons, but I’d say it mostly boils down to confidence.

The knowledge that nobody’s going to be laughing at your little guy, in fact the knowledge that they might even be blown away by it, is priceless when it comes to sexual confidence.

Well, pills alone just aren’t going to do it.

You’ll need a device to go along with it.

One such device is an extender, like SizeGenetics.

SizeGenetics, like most penis extenders, is a device that you “attach” to your penis and wear for several hours a day to achieve gains in both length and girth (though the most significant gains will be achieved in length).

There are definitely differing opinions of SizeGenetics and extenders in general, so we’ll walk you through, making sure you know what you’re dealing with.

Note: If you’re looking to gain some SERIOUS size, then I would recommend you take a supplement called Vigrx Plus along with the Size Genetics device. The increase in blood flow and libido will SKYROCKET your gains.

How SizeGenetics Works

size genetics reviewAs a penis extender, SizeGenetics is a device that you put on/around your penis, causing it to stretch and then grow, enabling it to be longer both at rest and in a state of arousal. It works on the principle of traction.

After selecting the correct size to encourage a small amount of growth, you apply SizeGenetics to your penis, and wear it for several hours.

You do this each day, and over a number of months, you’ll add on to the size of the device because the size of your penis will continue to increase, requiring you to do so.

What Makes SizeGenetics Different

I know what you’re thinking. “You want me to wear that thing on my penis for hours each day?

Are you crazy?” And that’s why, frankly, tension devices haven’t taken the penis enhancement world by storm.

People who manage to use them do find success.

But most people find it simply inconvenient.

That’s why the makers of SizeGenetics made sure it was as comfortable as can be.

It comes with spongy cushions and tubes to increase your comfort, if you find it to be lacking.

They do this because SizeGenetics knows that it won’t work if you don’t use it.

SizeGenetics Reviews

We’ve seen a number of SizeGenetics reviews from guys who’ve used it, and they are mainly positive, giving us the impression that if you use it, it works.

The only complaint lots of guys share is that it’s something of an inconvenient hassle to have to wear SizeGenetics for hours every day.

Lots of guys hope that they can get away with using it less or for shorter periods of time, but you just can’t if you want to get the kind of results SizeGenetics is capable of.

There’s also a number of very convincing before and after photos showing some HUGE increases in size. Check them out below:

My Personal Results

Back when I originally started this site, I kept coming across the Size Genetics device.

At first, I’ll admit I was a little intimidated.

The thought of strapping the thing on to my penis didn’t sound very appealing.

When I started to see the before and after pictures guys were posting though, I decided it might be worth a shot.

I ordered the comfort package, mainly because I was reading how important comfort is when it comes to extenders.

I received the SizeGenetics extender in the mail a few days later, and started wearing it right away.

Some initial thoughts:

  1. It wasn’t as easy to put it on as originally thought.

I had read a bunch of guys saying that putting on the SizeGenetics device was easy.

In my personal experience, this was not the case.

In fact, it took me about 45 min. to get it on the “right” way.

Luckily I’m a pretty patient guy, but I can see some guys throwing in the towel early here.

2. It’s not as uncomfortable as it looks.

At first glance, the SizeGenetics extender looks like you wouldn’t want to wear it for more than a couple of minutes.

After finally getting it on the right way, I noticed that it was actually quite comfortable.

It wasn’t like I didn’t notice I was wearing it, but I quickly because accustomed to the feeling.

SizeGenetics Pros and Cons

Advantages of SizeGenetics

  • It works for a lot of guys.

    If you use it diligently and especially in conjunction with enhancement pills, you should see growth.
  • There’s a 6 month money back guarantee.

Disadvantages of SizeGenetics

  • It’s expensive.
  • It requires enormous commitment.

    We’re talking about hours of daily use for months and months.

Where to Buy

SizeGenetics is available online through the SizeGenetics website.

There are a few different packages to choose from based on your goals and budget.

The starter package includes only the SizeGenetics device, and it sells for $199.99. There are more expensive packages if you want the carrying case, powder, and several more add-ons.Whichever package you choose, you’ll be eligible for the 6 month guarantee.

Conclusion

There are two things to remember about penis extenders.

One is that they provide a degree of success when it comes to penis growth.

The other is that they require a huge and extended time commitment.

SizeGenetics tries to mitigate that second fact by being as comfortable as possible.

The feedback we’ve seen seems to support that.

So if you’ve been thinking about trying out an extender, SizeGeneticsis a good choice.

If you are confident that you have what it takes to stick with SizeGenetics or any other similar penis extending options and put in all of the work and attention that it requires, then you are more likely to have good effects and gains to show for it.

User Questions and Answers



Can you use both devices, such as the SizeGenetics and Bathmate, during the day or is that too much for the penis to handle? -Carmine


You can use them both, but you'd have to make sure to work out a schedule that doesn't end up just making you sore. When you're sore, you're less likely to work at it consistently.- Rob

If I just want to grow 2 inches should I use the sizegenetics or the bathmate -Jay


Well, that depends.  If you're looking for girth, use the Bathmate.  If you're looking for length, use the Size Genetics device.  Personally speaking I would get the bathmate and do jelqing exercises along with it.  That way you get the best of both worlds (i.e. length and girth increase).- Rob

My guess is you're having some sort of allergic reaction to the baby wipes, but I don't know for sure. My suggestion would be to lay off for a few days to let it heal, then retry without the baby wipes.  If you don't get the same reaction, reintroduce the baby wipes.  If it comes back, then you know that's what it is.  Ultimately, if the problem persists, you should look into using the Phallosan Forte instead. It's SO much more comfortable so you won't have these kinds of problems.  - Rob

  1. Hay there Rob

    Rob here also so, I purchased a traction device a couple years ago and not even sure what name brand it but I’m sure their similar. Yes dedication is the name of the game here after 1 month I’ve seen a difference and excited about the final outcome.

    I’m using it cold turkey so to speak although it can be uncomfortable and should do as little climbing and bending over otherwise ouch. You don’t have to wear it forever so just suck it up, the other drawback with the device I’ve got you must snitch it up tight which cuts the circulation off probably by 50%.

    Have you any ideas which may help? Thank you for all the exercises videos and help……..the wife will love you also lol.

    1. Hey Rob,
      Yeah see that’s why I’ve been recommending the Phallosan Forte (review here) for this specific reason…it doesn’t cut off circulation like traditional extenders do. You’re in luck though, there is hope. Check out this Modified vacuum extender: http://www.autoextender.com/modifiedvacextender.html

      It’s basically an accessory for SizeGenetics and other extenders, that completely eliminates this problem. Hope this helps and let me know if you have any questions.
    1. Hey Dave,

      They’re not recommended for anyone under the age of 18. The primary reason is that you’re still growing, and it’s not known what effect it might have on your natural growth.

  2. Which product will increase girth and length in permanent basis? How long will it take to see the result and should I keep on taking product after seeing result?

    1. Hey Kiran,
      Go with both the Size Genetics extender (http://www.SizeGenetics.com) and the Bathmate. Using both combined will give you permanent length AND girth gains. Typically you’ll start to see initial results in the first couple of weeks, and the best results are seen around the 6 month mark.

      Here’s my review of the Bathmate: https://www.supplementcritique.com/bathmate-hydromax-xtreme-review/

      Hope this helps and let me know if you have any other questions.

    1. Hey Kyle,

      Yeah, you can try that. I’ve heard of guys using baby wipes as well, but the solution on them could possibly cause irritation.

      It can get pretty uncomfortable, so pretty much whatever you can find to make it better would be fine.

  3. I have value edition size genetics device. I’ve watched video. and I’ve seen something about lines on bars.

    I don’t see any lines. so I’m not sure wether it’s at 600 g or 900 etc for example. I don’t know if it goes up to 2500. if I can adjust 100 200 300 vs at a time or what

    1. Hey Nick,

      First off, you’re not going to get penis enlargement from any pill. I’d stay away from Xanogen and HGH Factors. They’re advertising is just pretty scammy. Sinrex looks good for performance enhancement, but don’t count on it to grow your penis.

    1. Hey Angel,
      Anecdotally, there are stories of guys getting as much as a 2.5 inch gain in size. I didn’t get this because I didn’t wear it for as long as those guys did.

      However, If you stick with it, there’s no reason you couldn’t achieve the same gains in size.

    I wonder is it really work as my penis will shrink in a day…when i put it on….will it slide out? and is there a minimum flaccid size required for wearing it ?

    Also, whats the difference between sizetrac and it ?
    1. Hey Jay,

      Sizetrac and SizeGenetics are pretty similar in that they work the same way. It’s really a matter of preference. I liked SizeGenetics, and the reviews are really quite good. It’s adjustable so you should be good for the size of the device. And no, the gains you get will basically be permanent once you get them.

  8. I can see that sizegenetics will work but its very expensive ,
    What is other option for length and girth that is affordable ?
  9. This thing is a piece of junk. I constantly slide out of it. It may stay on better if you’re already hung, but if you shrink too much you slide out. Once you begin sliding out, it puts a lot of strain on the head because it’s being squeezed thru backwards. I did notice it made the head mushroom out more from being pulled backwards. I’m very unhappy with it. It’s extremely difficult to put on and pinches the sides. It comes with different comfort holders, the only one that mildly works is the foam cylinder, and the foam agitates the head by rubbing against it when sliding out.

    I got a Bathmate afterwards and could not be happier with the Bathmate. I’ve gotten great compliments from the Bathmate results. I use the Hydromax X40.
    1. Hey Jeff,

      If you use it according to the instructions, you’ll be fine. But like any mechanical apparatus, if you aren’t careful with the tension or the activities you perform, you could experience pain or discomfort.

In the US, it’s 1-800-209-1670. In Australia, it’s 1-800-047-153. If you can’t get through with a phone number, you can email them at support@sizegenetics.com.

  12. Can you just wear it at night while sleeping? Also how would u wear it throughout the day without it being noticeable to anyone else?

    1. Hey Larry,
      The more you wear it, the better and faster it works. You could use it just at night while sleeping, but you’ll get better results if you wear it more.

      They’ve designed SizeGenetics to be the most comfortable device there is, and realizing that every guy is different, there are 58 different ways to wear it. So everyone can find a comfortable position.

      It’s also made small and discreet enough that you can wear it under your clothes at work, and no one will know.
      Let me know if you have any more questions.
