there loads of dads on the steroid board..... one of my palls, 46, been on gear all his adult life, just had twins with his new wife.. ive been on and off around 11 years, got my gf preg last year, in middle of a cycle...
if you have fertility problems before gear you probly will fuck your self up good n propper, if your ok before you start youl more than likey not be effected, thats my personal experience anyway
