About us
Substra makes a focused line of athletic supplements for people who actually read the label.
The idea
Most of the supplement aisle is proprietary blends, under-dosed actives, and claims that can't be backed up. We went the other way: a small range of daily products built around clinically-studied ingredients at honest doses, every one disclosed on the label.
What we make
A daily performance drink mix (creatine + electrolytes), two focus formulas (with and without caffeine), and an evening recovery formula. Designed to work together as one daily system — train, focus, recover.
How we're different
Branded, traceable actives. Third-party testing with a Certificate of Analysis on every lot. Manufactured in a cGMP-registered facility. No proprietary blends, ever.
