Pick the compound. Each ranking lists every one of our 77 scored vendors that sells it, ordered by the 10-point evidence rubric and then by verified price per milligram — with a product-page price and the date we read it for every row, and a buy box for the partners at the top.
24 compounds · 332 vendor listings with dated prices · no vendor is consulted, and partners rank where the evidence puts them.
Score first: ten checkable criteria — named lab, certificates that resolve on the lab's own site, per-lot certificates, measured net content, ungated pricing, an independent review base, consistent claims, sized pricing, a published legal identity, and a clean record. Then price per milligram at the size most vendors sell. A cheap vial from a vendor with nothing to verify is the most expensive outcome, which is why price is the second key, not the first. The scoreboard shows every vendor's evidence; the COA library holds the certificates we opened.
