BCAA's really are a bit different from a great many other NitroBuild Plus Muscle Building products. Rather than working to build muscle up, they help prevent muscle's break down during workout that is extreme. When you're lifting heavy-weights (or during long duration aerobic fitness exercise) your system will enter a catabolic state. This means muscle is breaking down for power applications. Muscle that is breaking down is exactly of what you need the alternative!
