These guys are simply the best. When I first bought my size genetics value edition, and it had an issue of a loosened screw, which led to the removal of the spring, in the hexagonal piston, I received a video, instructing me on how to properly replace the spring. My same value edition tool, recently stopped turning at the hexagonal piston and hand screws, on both sides, and got new parts ordered for me to my surprise.

1st Month for those on the fence It's been a month and I am pleased with the results have been amazing, My routine only varies on the days that I work I try to do it for at least 6hrs and my days off at least 10hrs, for those that have peryones(curvature) the first thing you will notice is increase in girth that's probably due to the lack of muscle tissue that has not grown typically on the side where it curves, you'll notice how the trunk or shaft of your johnson is the first thing that gets thick and strong which will already prove to work wonders when you get to action time, so after 1 month of use it seems like my girth has increased significantly and my length probably has close to half inch, but the most glorious aspect of all of this is that my wife cannot stop screaming when I'm inside of her(I swear this is 100 percent truth, for those that believe in God you all know swearing is a big deal), I also made her cry (lol ) which was a bit confusing at first cause I thought she was going through pain but she kept kissing me and told me afterwards that those were tears of joy and that she is amazed of how strong she feels me down there.My main purpose with this review is to address those who are on the fence about getting this device specially those with Peryones: - The size, girth and strength of your johnson is in a crippled state because one side(typically the side where your johnson is curved towards) of it has not developed muscle tissue to be in its optimal state, hence it means that because of it you have a reduced girth and and length just by having Peryones WHICH IS NOT HOW IT WAS MEANT TO BE, believe me is the equivalent of having a muscle imbalance, so far this is the best way to fix that muscular imbalance on your johnson. - It might sting a little bit: For those that stretch regularly or do yoga you will understand how muscle tears work , in my case with Peryones it stings on the side where the tissue has not grown or developed and I have to take deep breaths or change my breathing patterns according to the gravity of the sting(it literallyfeelsas if needles are getting pulled out of the side where you have the Peryones), if the stings get too overwhelming I remove the device and I let it rest until the stinging stops to put it back on and complete my hrs , if you do yoga or stretch regularly you won't have a problem reading when to take it off and putting it back on, but just remember because you have peryones your experience will not be pain free ,Everytime you put on the device probably around the 3rd or 4th hr of wearing the device it will literally feel as if needles are being pulled out of the side where you have peryones, just be patient and breath accordingly cause it I'll be worth the effort. DO NOT HYPER EXTEND YOUR JOHNSON, GO SLOW WITH THE EXTENSION AND INCREASE LITTLE BY LITTLE. - If you you feel uncomfortable telling your partner about the device just tell her the following in your own words(for those with Peryones): Say you magically stumbled upon information that led you into deep research and you finally found out that you have an unnatural muscuĺar imbalance(which is not a lie) on your Johnson and that you are going to get it fixed with a device, say something that goes along those lines and she won't give you issues, in fact she'll love you more once she starts feeling you stronger, longer and girthier(typically after 1st month of use). In closing: feel happy that you found a way to give your Johnson a workout thats effective and that can be worn anywhere without being detected, my curvature has not yet improved too significantly but my length and specially my girth has, I guess once the muscle tissue becomes more balanced that's when Mr Johnson is gonna start getting straighter, at least it feels that way so far. THE MOST IMPORTANT THING IS TO TRY TO GET AT LEAST 6 HRS A DAY AND DO NOT HYPER EXTEND which is how I have been doing it . Trust me, you will not regret it .

It definitely works, but be patient and consistent to see results

I’ve been using it for about six months and gained around one inch so far, wearing it 5-6 days a week for around 3-5 hours a day. I keep track of my hours and measurements in a spreadsheet (so far 400 hours in) and take photos of measurements to remind myself how much progress I’ve made.

The size increase is definitely noticeable and has been a boost to my confidence. I’ve seen some increase in girth too. It also makes you harder and for longer since it stimulates blood flow, so in that sense I plan to continue using it even after reaching my length goal. I wish I discovered the device years ago.

The device itself is very well-made with good quality material as I haven’t had any issues with it or parts failing, etc. It still looks brand new even after a lot of use. It’s comfortable to wear too but takes some getting used to at first with putting it on and securing a good grip (a bit of talc powder helps too). I find it's best to wear if you're laying down.

I’ve also been impressed with the customer support I’ve received, having had to email a few times along the way with questions and asking for advice, and they always reply promptly and helpfully. The same person replies to my emails, so it’s nice having consistency since they are familiar with me as a customer.

My advice/tips for new users - follow the start-up programme, be patient and consistent, clean the device daily, keep track of your hours and take regular measurements. I use the silicone tube as a strap and find that every few months or so I need to order a new one since it will lose its tightness overtime due to stretching, but it’s inexpensive to buy.

In my experience, the Sizegenetics stretching device is comfortable, but only if you know how to make it comfortable. I am uncut, so not any other stretching device works for me; I have tried vacuum devices and those have been the worst for me because my foreskin gets in the way. With this stretcher device, I use the silicon strap and the protection pad and those work for me. In the past, I have wore this device for 400 hrs and it did elongated my penis a little bit, but when I stopped wearing the device, I lost those gains. I am wearing the device again (it's been three months) but to be honest I have not seen much gains, only a small bit.

To Those Who Are Serious About Growth,
My journey with size genetics started a few years ago after I had recovered from a minor surgery where I was put to sleep, and the surgeon attempted to catheterize me and couldn’t get the Catheter in because of stricture. He used a surgical rod to open the passageway through my penis and unknowingly tore up my Urethra, causing severe scar tissue. After months of healing and contraction of inner tissue, I had lost almost half of an inch in penis length.

A urologist friend recommended the Size Genetics device to me. After using the device for several months, not in a very disciplined manner, I had barely gained back 3/8 of an inch. I decided to do a comprehensive study of penis scar tissue healing and enlargement. The first thing that I did after thorough research was put together a disciplined plan. I learned from a sports surgeon friend that you must give the body the proper tools to heal and grow. I use the device an average of 4 ½ hours daily, sometimes 5 hours. After stretching, I take 1,000 mg (2 capsules) of “Mother Nature” CAMU CAMU vitamin C from organic fruit. I take three capsules of COSOSAMIN ASU Joint Health (promotes ligament healing and growth) and 1 Nature Made Multi. I drink a protein shake of at least 35 to 40 grams made with Ancient Nutrition Multi Collagen Protein.

I started the planned aggressive program the first week in December, and I have grown in length a little over one-half of an inch. When used properly and with the right nutrition, the device works. I couldn’t be more pleased.

This works. I wore the instrument 6 hrs a day the 1st year, removing it every hour to allow normal blood flow before continuing... I grew an inch the 1st year. Every year after, I have been wearing the instrument 3 hrs a day, every other day...and I have continued to grow a 1/4 inch every year...I am absolutely thrilled and I will keep growing my penis likely forever! These gains I made, are erection gains, not just soft growth and my erection has gotten thicker and stronger as well. I did not have a small penis to start, but I want a huge penis. I am 3 yrs into doing this now. I have replaced the working parts once every year and purchased the extensions as I have continued to grow and the orders have always come. When I was young I started exercising my body with the intention to grow a good looking strong phisyque and now growing my penis is just the same. Growing a good physique or your penis is very similar... consistent stimulation, good nutrition and proper time to heal in-between...and time...and you will continue to grow and change due to the stimulation...it is not magic... I am so glad to live in this time of excellent engineering...to be able to have this fun. Thank-you engineers responsible and Size Genetics for offering this affordably.

Time+Effort+Discipline = Big results for my Manhood

Works great but it requires time, patience and endurance, do not expect results in less than a month. I have been using it for more than a year since April 2023 now in combination with a pump and those 2 has done wonders. It was hard to vet a grasp of it at the beginning and really weird because Hey you are venturing into the unknown... Do not forget to get your diet and sleep on point and get a lot of protein and minerals intake to help it grow stronger. I wish I had done this earlier because it give you a truly great ROI on your sex life and it is a mental boost as well. If you can grow your manhood what else can you do? Most people are making funny jokes about penis length but are not doing anything to improve it nor do they think it is possible and you get laughed at for doing so. They are those that do and make it happen and other who watch on the sidelines!

You have to believe, it works very well!

I have been dealing with Peyronie's disease for several years. I didn't want to go for surgery, I thought there must be another solution. I started looking and that's how I ended up with Sizegenetics. I was very skeptical at first about what they promised, regarding the increase in size but also about Peyronie's disease. However, I said I had to try, I had nothing to lose. The results were exceptional, from all points of view. The biggest problem was the psychological one, Peyronie's disease brings with it ED but also a decrease in size due to the decrease in the volume of blood circulating. Everything has changed since the beginning. I haven't treated Peyronie's yet but things have improved. And as for the increase in size, there is no doubt, it works. Just like it works in the case of ED.

Excellent quality

The design and engineering of this product is excellent. I have been using it for more than one year now, and I find the silicone tube noose fit me best. One tip would be to clean the tube every day with hot water and dishwasher soap, this will result in higher friction (more grip) which again makes it more comfortable. Before I did this the tube tended to slip slightly and that was uncomfortable.
