Here is another supplement sample from the T.O. Pro Show Expo back in June. Before this, I had never really put much thought into Aminos and BCAAs for use during my workouts, but after this sample was used, I felt like there might be something more to these. This sample is Muscletech’s Amino Build from their Performance Series. Below I’ll break down what’s in this supplement, and why you just may wish to start using it to help fuel your workout instead of just water.
