So glad i bought this one. Was a tough decision between the Size G and the X4 Labs but after reading up throught the net i decided to try the Size Genetics. I found a lot more sites saying how good this one works compared to the X4 Labs and after 3 months i can say that it works well for me too. Ive gained over an inch already, it may not sound like much but if i gain another inch in 3 months i’ll be where i want to be. I give this a good 99 from 100.

All i can say about this is that i am gutted it took me till the age of 33 to find it. If i had been using this when i was 18 it could have helped me out no end. I was always shy, in showers etc as i was never as big as the guys there but this has helped me gain so much i feel i would put some of them to shame. I know its only been a few months and most people are interested in erect length but the gains when soft interested me as well. I’ve got more than i expected so i give Size Genetics 97 from 100

After 3 months i can confirm for definite that Size Genetics works for me. I have measured weekly instead of waiting a full month with some positives and negatives. The thing is when you first start you can gain half a cm in a week but the following week 2mm seems bad. The thing is after chatting on a forum someone told me that 2mm every week means that in a year that would be 10cm or 4 inches. He did warn me that gains would slow down after a while but i can still dream of getting to the 11 inches that would take me to. I am pretty sure that would be too big and would stop before that but nice to know it is possible. Unlike me it is better if you have patience and measure monthly, it is better to see a 15mm increase as opposed to between 2 and 5mm a week. Worth 98 from 100 any day.

What surprised me most about Size Genetics was how comfortable it is to wear. I had used an old string noose type extender years ago and decided to try again. I only bought this because i was impressed with the strap design and am so glad i did. I’ve gained almost 2 inches and could easily gain more if i needed to. You have to keep upping the time you wear it but as i work at home it’s easy enough for me. Comfortable, discreet and even though it’s not advised can be worn overnight if you don’t mind going against what people advise you. 99 from 100.

I bought Size Genetics as a last resort having tried pills and a penis pump. I truly needed the gains though unlike some on here. At just over 4 inches sex was near impossible, some positions anyway but i can now say i’m nearly 6 inches in less than 6 months. That may not seem a lot to some people but to me it’s near enough a miracle. I’m now a lot more comfortable going to bed with women than i ever was before. A well deserved 100 of 100 and one of the only things i know that works.
