About Precise Protocols

Supplements should read like a lab report, not a billboard.

We started Precise Protocols because the supplement aisle is built on proprietary blends, vague "support" claims, and doses too small to matter. We do the opposite: one clear job per bottle, every active printed at its clinically-studied amount, and a certificate of analysis for every lot we ship.

Clinically dosed

Every active is included at the amount used in published research, not a pixie-dust sprinkle to justify a label claim. No proprietary blends, ever.

Tested every lot

An independent lab verifies identity, potency, heavy metals, and microbials on every batch. We publish the results, look up any bottle by its lot number.

Manufactured in USA

Manufactured in a cGMP-registered facility, gluten-free, non-GMO, and vegan. Backed by a 90-day money-back guarantee, even if the bottle is empty.

Our standard

Built by people who read the studies.

Our formulas are developed with a scientific advisory team of pharmacists and nutrition researchers, then reformulated whenever the evidence moves. If a dose isn't supported, it doesn't go in the bottle.

Our story

The name is legacy. The mission is not.

Zenmen isn't a men's brand, it's a name we grew from. What stayed constant: master-herbalist formulas, honest labels, and coverage for both threats a tick can carry.

Master-herbalist formulas

Every formula is built by herbalists working from the Buhner protocol literature and modern laboratory research, not marketing trends.

Honest labels

We list every active at its exact dose and publish a third-party Certificate of Analysis for each lot. No proprietary-blend hiding.

Organic sourcing

Herbs are grown primarily on Montana Certified Organic farms, harvested at the right window, and double-extracted for potency.

Coverage for both threats

Because a tick can carry bacteria and parasites at once, our system spans both, so you're never treating half the problem.
