Vendor atlas · Updated June 2026

Catalogs organized by what you're trying to research.

Recovery. Metabolic. Growth hormone. Each entry in the atlas ranks vendors on documentation depth, format diversity, purity verification, shipping, and price-per-mg — so the catalog matches the goal.

The atlas

Three research goals, three vendor rankings.

Each ranking starts with the goal — what protocol are you running — and works backward to which catalog actually fits it.

The brief

An atlas, not a leaderboard.

The same vendor can be #1 for one research goal and #5 for another — because catalog depth, format range, and price-per-mg shift with the compound. We treat each goal as its own ranking, with its own weights, and we re-evaluate every six months.

About the project

How we score

Seven criteria. No paid slots.

Catalog depth, lab documentation, purity verification, format breadth, payment flexibility, shipping logistics, and price-per-mg. Vendors don't pay us. They can't promote into a ranking — and they can't promote out of one.
