Im looking for a steroid that would help out with cardiovascular workouts and such
I do alot of running and swimming (when I get a chance) and I was wondering if theres a steroid I could use that would make my blood basically more efficient
what I mean by that is something where i.e. swimming I could hold my breath longer or in running I dont get so out of breath when running
is there a specific one I could use?
thanks
Carl
