Might be a dum one?!?!

Which one of these are better for sprinting and a quick reason would be greatly appreciated: (EQUPOISE,winny and test) or (PRIMOBOLAN,winny and test).

Now I know about Equpoise and horses so I hope this isn't too stupid of a question. Anyways I heard things like certain anabolic steroids take oxygen from a runner, what is that all about????

Also is there something else that would be better or something that is really popular with running athletes?

Later Guys!

i would say winny,strength stamina ,plus good ol ben jhonson used it oh wit i forgot someone slipped it in his orange juice.eq low water ,strenght and increase of red blood cells endurance .and test prop to kinda keep everything in tact,libido ans etc.also another one would tren.
