Sourced exclusively from the world's purest and most potent protein technologies, it provides a complete spectrum of highly bioavailable amino acid microfractions derived from the most advanced processing methods and precision-targeted to facilitate muscle repair, recovery, and growth.

Because it is entirely free of the damaged protein fractions and impurities so common in typical protein formulas, Peak Protein™ always possesses a clean, light taste and lusciously smooth texture.
