Vendor links are temporarily offline while we review our referral and linking policies. Listings remain for price transparency.

These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.

"Cheapest" is the lowest in-stock, first-party list price per milligram for each compound. Blends, bulk vials, out-of-stock, and non-injectable forms are excluded so a comparison is like-for-like. A discount code may lower checkout further, but codes never move the ranking; it is pure $/mg. "Spread" is the dearest tracked price divided by the cheapest, and "sources" counts distinct sellers rather than listings. See the methodology for exactly how prices are captured and normalized.

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.
