"Advanced Amino" certainly delivered what was advertised. It's the best amino supplement I've ever experienced, and I'm a life long athlete whose results in the gym and on the track are tangible, measureable, and long term. One may get an illusory psychological effect from a given supplement for a short time, but nothing can fool the clock long term when it comes to times performed on the track, or amount of weights being used in workouts, in the longer term. I've experienced better and quicker recovery from workouts as well. And one of the unexpected benefits has been weight control, because Advanced Amino tablets each day knocks out food cravings completely. It's truly a great supplement for anyone looking to maintain muscle and condition..
