a lot of the srinters are using , dont listen to what they are saying about being clean! , a lot use HGH with a fast acting insulin , as well as T3 , sometimes some test suspension as well as a little epitestosterone thrown into the mix (clears drug test pretty quickly , but too much epitest will fail the drug test also). Lots of them use prozac , they claim it helps them recover (don't know if this is true).
Anavar and winny are favourites to throw in when they are sure they will not get tested.
Yep, its true the srinters rattle when shaken! , track and field athletics is totally corrupt with drugs , most athletics federations cover up positives all the time! , what really pisses me off is the way they try to say the sport is clean and occasionally ban some poor b*****d who they think they can afford to lose!
