Hey everyone, I am a hockey player trying to get to the top. Main goal is speed and power. Size will be to gain as much as 15 lbs, but not any more than that. I have taken just a basic cycle for the past 2 summers and have seen improvement, but just not enough. So I would like to start a stack. I am not sure as to what to take and what not. I have been told a variety of things but do not know which to go with. Any suggestions are appreciated.
