Rule 1 Protein is a whey isolate and hydrolysate blend with no concentrate, gums, or fillers - 25g protein at up to 87% purity by weight, 6g+ naturally occurring BCAAs, Informed Choice certified.
Protein PowderThis is built deliberately narrow: just whey protein isolate and hydrolyzed whey protein isolate, skipping the cheaper whey concentrate, creamers, and thickening gums that dilute protein purity in a lot of blends. That gets the brand to an 87% protein purity by weight, with 25g protein and over 6g of BCAAs occurring naturally from the whey sources rather than added separately. It's fast-digesting given the isolate/hydrolysate base, which makes it a strong post-workout pick, though it works fine any time protein is needed. Informed Choice certified and tested for banned substances, which matters for competitive athletes.
