Until you guys break up and she uses it against you..it wouldn't be the first time, trust me. I told an old friend of mine (used to be my best friend), we got into it one day, and we went rolling around in the dirt one day in a fist fight. Didn't take but two hours and he was calling the cops and my G/f up to tell them I was using AAS. so then my g/f at that time knew...well we eventually broke up as I got caught cheating on her, and then she calls up my parents and tells them....
I'm tellin ya man, don't tell ANYONE ANYTHING about your AAS useage...I once thought that my old best bud would be my best bud forever..I found out the hard way....just a tip.
