The Science

No Fluff. No Filler. No Compromise.

We were built on a simple principle: every ingredient must have a published, peer-reviewed reason for being in our formula.

Clinically Dosed Formulas

We use ingredients at the exact doses proven effective in published studies — never underdosed fillers.

Zero Proprietary Blends

Every ingredient, every amount, on the label. Because hiding what's in your product signals something to hide.

Third-Party Testing

Every production batch is independently tested by LGC for banned substances before it leaves our facility.

Formulated with Athletes

Our team of sports scientists work with competitive athletes across powerlifting, athletics, and CrossFit.

Certified & Approved By:

Informed Sport ISO 22000 GMP Compliant Vegan Society LGC Tested
