About
We build supplements that show their work.
Proco makes evidence-only supplements for men's vitality — testosterone, energy, drive and recovery. Every formula is built on peer-reviewed human clinical trials, dosed to the ranges those trials actually used — not animal studies, not mechanistic theory, not a "clinically inspired" fraction of the real dose. Every batch is independently tested. Every Certificate of Analysis is available on every product page.
Why we exist
The men's supplement industry has a transparency problem. Proprietary blends hide what you're actually taking. Doses are chosen for cost, not efficacy. Marketing claims are everywhere; trial data is almost nowhere.
We built Proco to fix that: exact ingredients, exact doses, independent testing, and the evidence tier behind every decision — all visible, all the time. Where the evidence is strong, we say so. Where it's traditional use rather than deep clinical research, we say that too.
Our standard
- Every formula dosed to the ranges used in the human trials we cite
- Every batch independently tested by a third-party lab
- No proprietary blends — exact ingredients and doses, always
- Evidence tier disclosed per ingredient, not just per product
- Certificate of Analysis available on every product page
"Most men's health supplements were proprietary blends and T-booster pixie dust. So we disclosed every dose, matched them to the human trials, and let the label do the talking. If the evidence isn't there, we don't stock it."
