Why isn't a listing in the price comparison?

Some listings can't be compared head to head, so they are flagged and kept out of the headline numbers. Blends of two compounds have no honest single-compound price per milligram and appear in their own section. Wholesale-size bulk vials are marked so they don't pass for the retail cheapest.

Oral, nasal and topical forms are separated from standard vials, and a price far outside the compound's median is flagged as an outlier so one mispriced listing can't define the cheapest.

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.
