Brand - Rule 1

A NEW STORY - FOUR DECADES IN THE MAKING

Rule 1 are Athletes, Bodybuilders, Crossfitters & Powerlifters. Guys who've lifted a few million lbs & downed a few thousand scoops of protein. They're also supplement pros who've done this before. Guys who know the difference between the good stuff & the over-hyped wannabes. For those who are serious about getting the best out of lifting are obsessed with 1 thing. Protein. And a quick comparison of top-selling brands shows R1 PROTEIN delivers more of what we all take protein for...protein!

THE SOURCE OF OUR STRENGTH

When sourcing the raw materials that go into Rule 1 Proteins products, Rule 1 focus on purity, potency, and a research-backed reputation over price. Only ingredients that pass Rule 1 Proteins’ stringent standards for safety, quality, and efficacy are ever considered. We also choose strong, well-respected branded ingredients like CarnoSyn®, Nitrosigine®, Infinergy™, HydroMax™, and TeaCrine® to create formulas that deliver the results that our customers expect.
