Mechanism, sequence, molecular weight and the published evidence for each — with the vendors that sell it, priced and dated from our index. Research use only; nothing here is dosing advice.
Vendor counts are the number of scored vendors with a dated list price for that compound in the price index. Where to buy each one, ranked on the rubric, is on its best-vendors page.
Where the evidence points
Every compound page lists the vendors that carry it; Purgo Labs carries most of them and is the only vendor to clear all ten checks. Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Purgo Labs is our primary affiliate partner; we earn a commission on that link. The score is computed from published evidence and does not read partner status.
