Enduro Beta red

[dsimon]

Is anyone an active user of this stuff? I bought a small bag to test it out so far so good. I have been following the instructions until yesterday. so yesterday I just mixed it in a water bottle and drank some about 20 minutes prior to exercise and the remainder of the bottle during. I feel like it helped me push harder through the workout.. I feel like I whooped my arse im so tired today could it be the BCAA. or the open blood vessels?
