RULE 1

The team at Rule One Proteins is made up of supplement pros with years of experience under their belt. They’re also people who know the difference between what works and what’s an over-hyped formula. As serious athletes, bodybuilders, cross-fitters, and powerlifters, they’ve tried all the sports supplements as they’ve lifted a few million pounds and downed a few thousand scoops of protein. If you’re serious about getting the best out of lifting, you know that protein is key. Take a look at the Rule One formulas, and you’ll see that it delivers more of it, with an industry-leading Protein Purity Percentage (PPP) of up to 87%.

With its state-of-the-art production facility in Aurora, Illinois, Rule 1 is one of the few great sports nutrition companies that manufacture in every product category. From the very beginning, Rule 1 has always taken a hands-on approach to maintaining the very highest standards of quality.

When it comes to sourcing the multitude of raw materials that go into Rule 1 Proteins products, the company focuses 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 considered. They also choose strong, well-respected branded ingredients like CarnoSyn, Nitrosigine, Infinergy, HydroMax, and TeaCrine to create formulas that deliver the results that you expect. Our flagship protein is made with super-pure 100% whey isolate, fast-acting whey hydrolysate, and virtually nothing else.
