Re: Crossfit Supplements?
Not a huge fan of Syntha-6...it messed up my stomach every time I took it.
What are you looking for in a supplement? A lot of them have been discussed pretty extensively in the past.
Some popular ones around here beta-alanine, creatine monohydrate, citruline mallate (I don't know much about this one, though). I think quite a few people take ZMA for recovery as well.
As far as protein (and basically everything else, actually) goes a lot of people are fond with AtLarge Nutrition, the owner posts here often and will answer any questions you have which is a plus.
