Have had no noticeable side effects from this. i am taking 6 a day, they seem to help reduce total time to recover which is good. Havent noticed any other significant improvements anywhere yet. will update if and when i do. They alway arrive quickly and packaged well.
Great product, and very potent. I train with a PT twice a week and go running 3 times a week and these are great both before and after the heavy work to aid recovery and muscle building so that i can run between workouts! Although only get true results when combined with a good diet. Also, because BCAA is a recovery aid, it works great as a hangover cure... take a course of these before going to bed after a night out and again in the morning with breakfast and you'll feel so much better and be ready to have a good day instead of spending the day crying in the foetal position!!!
