Hello. I need a little of info. Im currently using Letro for reverse a little problem of Gyno ( i will be running it for nearly 1 month). I have read a lot about and i have found that letro kill the sexual drive. So i have read that Test is needed to fight this side effect. So if i dont use Test (i use letro alone).. there is possibilities that i will go to have erection or impotence probelms later? Are this side effects permanents? (i ask this because i cant find a site to buy Test right now). Thanks.
