I've been keeping my supplementation fairly basic, only going with supplements with strong white paper (clinical research) rather than worrying about brand names, celeb endorsements, fancy packaging, etc. As of now, the only ergogenic aids I'm using and have thoroughly enjoyed are: Creatine monohydrate - time tested, scientifically backed, great for explosive strength, slight gains in size, fullness and increase in pump Arachidonic Acid - multiple double blind placebo controlled university trials on trained athletes confirm it overwhelmingly safe and effective for strength and size. Betaine - 2.5g a day for strength and size increases, inexpensive and the newest addition to my arsenal Beta Alanine 3g/day -cheap, fairly effective for increasing endurance HMB - this one shines for me, 4g a day does me wonders for improving strength, and increasing recovery. I can train w more frequency when on HMB and feel less fatigued in the days following a grueling session. And of course Whey Protein... anything that I'm missing?
