How is the vendors page top 10 chosen?

The top of the vendors page shows up to 10 vendors chosen by one rule: a Vendor Score of 80 or more, then cheapest against the market. For each compound a vendor sells in stock, its cheapest clean price per milligram is compared with that compound's median, counting only compounds with at least 4 comparable listings from two or more vendors.

A vendor's position is the median of those comparisons, and it needs at least 3 of them to qualify. Affiliate status is not an input, and the list is recomputed with every price refresh.

All help topics · Answers restate pepmg's own pages; the linked section is the authority.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
