i generally don't want to pay for supplements (they get pretty expensive) and i don't feel like i need anything. if anything my diet could be a little better - that would give me more bang for the buck right now. this spring when i start to gear up for races, i'll probably take a little whey protein after hard training sessions. i eat a lot of clif bars however, which is probably more food, but i kinda think of it as a supplement too.
