I have developed a 3 inch penis when used to be 2 inches. Success was achieved through jelqing and masturbation and such techniques. I will continue until 4-5 inches is achieved.
I must say that there are tons of these creams on the market and choosing the best one can be quite challenging. I suggest to check this out www.lustaci.com/best-breast-enhancement-cream/ might you can find an answer here but as I say THERE are lots and lots of cream out on the market. Have time to look for a good review, research for feedbacks, and check if they are FDA approved.
