Optimum Nutrition Platinum Hydrowhey is the fastest, purest, most advanced whey protein we've ever developed. In a word: excellence. By hydrolyzing the protein in this premium formula we've created our fastest-acting whey protein yet. Hydrolyzing breaks larger proteins down into smaller pieces that are able to get into your system rapidly, enabling your muscles to start rebuilding quickly.*
For added effectiveness, we've also enhanced this revolutionary formula with micronized branched chain amino acids (BCAAs). In addition to being fast, Platinum Hydrowhey is also ultra-pure. That's because it's made entirely with hydrolyzed whey protein isolates. So there's no excess fat or cholesterol to slow down your progress.
