Good Looking Loser’s Sizegenetics Review
updated: February 22nd, 2014
Over the past 8 years, I’ve tried several male enhancement devices including 2 different penis extenders. Other than the Bathmate, all of these devices were pretty underwhelming and difficult to wear.
At the end of January 2012, I decided to try the Sizegenetics extender because it had a money-back guarantee and promised “no slippage” or “pinching,” which was the biggest problem with the other extenders. Perhaps more importantly- my friend said it works really well.
As of this review (June 2012), in 7 months, I’ve gained about .5″ of length.
This might not seem like a lot, but I had a fair enough of male enhancement experience prior and I’m fairly “maxed” out. I haven’t gained length in about 2.5 years.
If you are new to PE, you will likely gain this amount in half the time or less.
I feel comfortable recommending the Sizegenetics because I use it, have gotten RESULTS with it and can compare it to other similar products.
How Does Sizegenetics Work?
In short, this penis extender works by applying moderate tension on your penis throughout the day. It keeps your flaccid penis “extended” and does not allow it to naturally retract. The tissue is gradually stretched and broken down overtime. With adequate rest periods, the penis tissue* rebuilds itself and becomes stronger and specifically- LONGER.
This is similar to the hypertrophy (growth) created by resistance training (lifting weights) on skeletal muscle.
*Penis tissue is made of 3 types of tissue (notably muscle tissue and organ tissue), it is not voluntary skeletal muscle like your biceps or quads- but it is made of some ‘smooth’ (spongy) muscle tissue.

Why is Sizegenetics Better Than Other Extenders?
Several reasons, i want to give you specifics. If you’ve tried other extenders, you’ll probably know what I’m talking about.
COMFORT = RESULTS
This is the most significant aspect, the Sizegenetics extender is BY FAR the most comfortable device that I have used.
You will need to consistently wear your extender for several hours a day.
Although this generic penis extender had a strap, not a noose, there was considerable pinching
I previously owned the AndroMedical extender and the Platinum Penis Generic extender by B&G International (see picture). These were not very comfortable and it became a pain in the ass to use them.
The AndroMedical extender kept falling off- not a great thing if you are sitting in class and it falls down the side of your pants leg. The generic extender kept pinching my dick. After 2 months, both became too painful to wear for more than 40 minutes.
I also used drink a gallon of water a day, it was completely annoying to remove and reattach these uncomfortable devices, especially in a public bathroom. Driving and climbing stairs became nearly impossible. I ended up selling the AndroMedical extender. The other generic extender is sitting in a box in my closet.
In order to get significant results, you need to wear the Sizegenetics for at least 4 hours a day. 8+ hours is even better.
(see below for a beginner’s routine)
Ideally, an extender will be part of your lifestyle. Not a hassle.
You need to be able to take it off and put it back on after you use the bathroom. It should be comfortable when you are walking around, driving, sitting or even when you bend over. It should not be pinching your dick or slipping off. Pinching and slippage are painful. You don’t want it to begin to hurt as your studying, at work or hitting on chicks at the mall. After sex, masturbation or following manual exercises, it’s important to wear your extender to prevent ‘turtle dick’. The last thing you want to do is put a painful, restrictive device on it.
Comfort is super important. I can’t emphasize that enough. Even the most dedicated guys can’t wear a device that begins to hurt after 10 minutes.
This extender is the most comfortable male enhancement device I have used.
I’m wearing it right now as I’m typing this review, drinking green tea, cooking chicken on the George Foreman and watching ESPN. How’s that for multitasking?
*SOFT PLASTIC RUBBER STRAP, NO NOOSES*
This is largely what makes it so much more comfortable than the other extenders.
Sizegenetics has a soft plastic strap that holds your penis in place without slippage or pinching. It keeps a consistent amount of tension on your penis and you do not have to adjust it until you take it off.
The other extenders I owned all had cheap “nooses” that are either always- too tight (pinching) or too loose (slipping).
These nooses would always dramatically stretch out after just a few weeks. When they stretch- they don’t hold your penis as well. This causes significantly less tension to be applied and ultimately your penis will always “slip” out. After the bands stretch out and can’t secure your dick, the system is basically worthless.
*EXTRA PADDING (Full System)*
There is extra padding for the area that holds your penis.
The other extenders have a cheap plastic piece that holds your penis. Your penis naturally adheres to this piece which makes taking it off pretty painful, especially after wearing it for 2+ hours. It felt like taking a band-aid off an open cut. It was always a short, quick, acute pain- definitely not pleasant.
Nothing like that with this extender- easy on, easy in and easy off since your dick is surrounded with padding.
* From member feedback, if you are uncircumcised, it is probably a good idea to purchase the extra padding (the full system). I am circumcised, so I can’t comment however.
What Can I Expect from Sizegenetics?
You can expect permanent LENGTH GAINS over several months if you legitimately make the effort to use it.
The clinical study below will provide the best guesstimate.
There are also progress logs from several our members that you can check out.
UK board certified physicians and plastic surgeons tested the Sizegenetics extender and published the results in the March 2009 edition of the “British Journal of Urology International.”
The Results Indicated the Following:
6 month average growth= 2.3cm (1 inch)
12 month average growth range= 2.55cm to 5.1cm (1 inch to 2 inches)
All the men in the study had a starting penis size no bigger than
At 6 months, the men saw an average size increase of 2.3cm (~1 inch) which was considered statistically significant.
At 12 months, the men averaged a final growth between 2.55cm and 5.1cm, between 1 and 2 total inches. The main variable was the daily length of time the individual wore the extender, all wore it for at least 4 hours. The guys that wore the Sizegenetics extender more often, had more length gains.
My Summary of the Sizegenetics Study
- Commentary: Clinical Study in the March 2009 “British Journal of Urology International”
This is from the clinical trial that documents % improvements of length gains over 24 weeks
Official clinical study- Sizegenetics_Clinical_Study.pdf
Published in: BJU International; Volume 103, Issue 6, pages 793–797, March 2009
What Will I Gain and How Fast?
If you have never done any male enhancement, you can likely expect the gains shown in the chart above. Most guys seem to get these.
The clinical study suggests 1 inch in 6 months, which is a lot.
If you combine the manual exercises with the extender, you may gain even faster. There’s really nothing that will give you permanent gains faster than this combination.
If you have been doing the penis enhancement for a while and add the Sizegenetics extender to your routine- you can expect to see increases in length that may have otherwise plateaued. It’s hard to predict. I’ve gained nearly .5″ in just about 7 months. (January – June 2012)
Sizegenetics Reviewed and Featured in GQ Magazine (UK)
One of the editors of GQ did his own review.
He gained over .5″ in 4 months, that’s pretty good.

What If I’m Uncircumcised? Will Sizegenetics Still Work?
If you’ve seen my pictures, you’ll know that I’m circumcised. The vast majority of guys that are cut will find the system quite comfortable, especially with the extra padding.
12 months of user feedback suggests that uncut guys are less comfortable in this device. Thankfully, there is an easy and super inexpensive solution if you are uncircumcised.
It’s called the “VLC Tugger” and it’s a modification that you can add-on to your extender. Some say it makes the extender significantly more comfortable for uncut guys.
Here is a review of the VLC Tugger from an uncircumcised guy that also owns Sizegenetics and can tell you what to expect.
How Do We Know That You Have a Big Penis and Really Do This Stuff?
I don’t mind showing that I USE EVERYTHING I recommend.
I started out pretty average (~5.3″), I’m somewhere between 7.15-7.25″ now.
Update: November 2012, I’m somewhere between 7.25-7.35″ now.

Where Can I See Before and After Pictures of Guys That Have Used ONLY the Sizegenetics Extender?
I tracked down some before and after pictures from guys with no previous male enhancement experience that used ONLY the extender.
I included some of my own pictures, but remember- I’ve have extensive male enhancement history.

Should I Get the Bathmate/Penomet or Sizegenetics?
I get asked this a lot, here’s my opinion-
I always tell guys to get a Hydropump first.
The main reason is because the Bathmate/Penomet are a lot of fun, you see gains quickly and guys get excited about their male enhancement goals. Guys see the gains quickly and come back to thank me.
In reality though, over the LONG TERM, Sizegenetics will be a better device if your goal is permanent length gains. It usually takes longer to see obvious gains however. I want you to know that. If you are impatient and debating between the two- go with a pump.
Both devices work great if you are committed to using them, I wouldn’t be recommending any of them if they didn’t work or I didn’t benefit from them.

I wouldn’t be recommending this system if I thought you would be returning it.
Still, I want you to know that you have that option. That’s one of the reasons why I bought it back in 2012.
If it sucked, I would have sent it back. If somehow you don’t like it after giving it a legitimate try, I encourage you to send it back.
They have AN ACTUAL PHONE NUMBER- 1-800-209-1670.
I’ve never called in, but I feel this is pretty important because the other overseas companies that sell male enhancement packages offer ABSOLUTELY NO WAY for you to contact them for customer service or a refund.
Although it’s “overseas,” it ships from jolly ole England – you’ll have it in less than a week, I’ve worked with them for almost 2 years now and the customer service is excellent.
