I have mixed feeling me about this product. On one hand, yes my workouts do improve. I’m focused and excited for each workout. As for the serving. I think it’s a bit too much. Obviously musclepharm wants to sell more so they’re going to tell you to take more than you would need, but that’s the case with basically every workout supplement brand. The few times that I’ve taken a full amount were on max out days and performance tests while playing college sports. I don’t think that my lifts improved but what I did notice was that I was getting angry at the little things. Once I came down I realized how emotional I was getting about things that normally don’t phase me. It was weird, and I’ve never had an experience like that. I still use the product, but I don’t think I’ll ever go on to use the full amount. It’ll save my wallet and any other troubles that may follow. Hope this helps someone!
