Some links are affiliate links. We may earn a commission at no extra cost to you. Sort: in-stock items first, then by lowest price per milligram within each bucket.
"Verified" marks vendors with at least one independent third-party purity test for this peptide, aggregated from Finnrick Analytics. "No test on file" means we do not have a third-party test on record — not a claim that the product is untested.
Why price per mg, not price per vial?
Vial sizes vary across vendors. A 10mg vial at $90 is cheaper per milligram than a 5mg vial at $50, even though the smaller vial has a lower sticker price. We normalize every listing to dollars per milligram so cross-vendor comparisons are apples-to-apples.
Format matters too. Nasal sprays, oral capsules, and lyophilized vials are not interchangeable on a $/mg basis — bioavailability, dosing, and effective concentration differ. Format is shown as a badge on every row so you can filter to one delivery method before comparing prices.
