My son swears by this.  He loves it and says that he noticed a difference in his workouts, or how he felt before his workout, the first day that he used it.  It does taste good, which I can not say about other BCAA supplements that I have tried.  My son works out regularly and has lost around 45 pounds in the last year.  He is very picky about his supplements, and we have both tried a lot of things in the past year.  I have already ordered him more of this Pure Nutrition USA brand BCAA Powder because in his opinion, it works the best.
