the only steroid that will be of any benefit to the OP is EQ, that IS ALL.
all other steroids are counter productive to running
do you have any running background, and have you used steroids while running? I'm talking real running, not jogging a lap or doing the elliptical at the gym. if you did you would be agreeing with me instead of posting nonsense like "you are trying to sell supplements" GTFO with that bs. what supplement did i try to sell in this thread? no supplements help with running either.
no such thing as a magic pill, you need to RUN MORE to get good at running. that is how it works. and no taking steroids doesn't help, it makes it worse.
