OP, you don't want to mess with Cheque drops, halotestin, methyl-tren or any other steroid like that. Just plain dumb in my opinion.
If and when you get into powerlifting, and you go to bench press 800+ lbs... then take some of the said compounds... until then, there are much better AAS to use. If you are a track athelete, there are much better compounds out there. Which ones you ask? Look at who got busted in the olympics. Take what they were taking. Make sense?
I don't really understand using steroids in athletics though... if you win, can you really live with yourself as a cheater? I mean, in bodybuilding, it is you against the iron, and most of us do this kind of stuff for aesthetics... and because if you are competing in bodybuilding at a serious level, everyone is on juice and the playing field is even.
