First, kudos to the successful surgury.
Secondly, if I recall correctly, you are an NCAA athlete? I wouldn't mess with anything that could get you into a situation with codes and rules (IGF). Few things would be more painful than working your way back from surgury only to be busted and lose you chance to play... would be all for nothing.
The only thing that comes to mind was what Red Wolf mentioned, powerfull. It's safe, and even though it may not do much since you're young, it couldn't hurt. Dose a bit higher than usual, say 6 caps daily spread out evently.
