I remember 2 decades ago the biggest thing in commercial sports nutrition supplement biz was ester peptides and creatine then beta alanine from what I see on the labels especially endurance formulas is micronized aminos and herbs although I make my own supplements I would have to say xtend by xience is one of the best products there is in stores. Whats your take whats the latest in commercial sports nutrition again I don't buy I make my own supply.
