hooch-5, for glutamine it's .35g per kg of bodyweight. So divide your bodyweight by 2.2, and multiply this # by .35. This is how much glutamine to take a day (or workout days only, depending on budget). Take either half before and half after lifting or throughout the workout. I believe the dosage for BCAA's is the same (a LOT of pills to swallow) and use powdered glutamine, capsules arent cost effective.
For one of the best supplements (although expensive), get glutacene and Nitromine.
