oh i know he's looking for winstrol
winstrol is rampant in the IAAF, but none of those people are competitive at that level because of winstrol alone.hell i use it still, but the foundation is built on solid training principle, just like BB.you can shoot winny til it's all your veins pump and you still won't have class A competitive speed wo/ solid speed drill training.i'm not talking about "oh, i did my speed drills w/ the team and now i'll be fast soon".i'm talking intense attention to detail mechanical response training.when i coach hurdlers or sprinters, it's is literally, 50% of the workload.sprinters/hurdlers do their training workouts to enhance leg turnover,breathing,etc, but reaction time is what makes great athletes.
