I've tried several Amino supplement in the past this is by far the most effective product I have come across. It gives my body the aminos it needs during a hard workout weather static lifting or a crossfit workout. The taste is better than most I've tried. Most Amino as I've taken in the past are too sweet or too bland RSP did a great job with the taste. The Energy Formula included and the amino blend is sufficient but doesn't leave you jittery or give too much of a stimulated effect post workout. Everything you need for your workouts is in this tub either pre, intra, or post. !
