"I love this. I also take Controlled Labs Purple Wraath for BCAA's, but that has some stuff in it that gives you a lot of energy. BCAA's are important before/during/after your workout. Especially after working out in the evening, I want to supplement BCAA's on top of what's in the whey protein, but I don't want the energy Purple Wraath will give me, so I use this stuff. This is a complete and rich BCAA profile that I feel is really effective. And I can get more BCAA's without having to load up on more protein."
