Flame me if this is dumb; I'm a total noob with no experience with anything stronger than creatine.
If I wanted to do a 6 week cycle of something to help with sprinting ability, would Osta or S4 be more beneficial? I see lots of people recommending GW to runners because it is good for V02 max - but for anaerobic running, that becomes irrelevant.
Osta has lots of human tests, S4 doesn't, which is why I'm leaning towards the former.
If they're both essentially doing the same thing - increasing lean muscle mass, decreasing fat - is there any reason to think one would be better at all in increasing peak power output?
Help out an idiot.
