Choosing a supplier
Peptide prices per milligram — Best Chinese Peptides
In short
Sourcing guide, in short: Price per milligram is the fair basis for comparing peptide offers, since vial sizes, bundle quantities and shipping all vary between vendors.
Normalise every offer
Divide the total price, including shipping, by the total milligrams across all vials. A cheap vial with a small fill can cost more per milligram than a larger one.
Where the markup sits
Domestic research resellers often relabel material bought from overseas manufacturers and add a substantial markup. Compounding pharmacies add clinical and regulatory costs on top. Buying closer to the manufacturer removes most of that markup.
Current examples
Among Peptaura's top sellers, starting prices include GHK-Cu from $0.06/mg, tirzepatide from $0.29/mg, KLOW from $0.31/mg, retatrutide from $0.48/mg, MOTS-c from $0.53/mg and BPC-157 with TB-500 from $0.91/mg. Prices change with stock and vendor, so check the live listing.
Questions buyers ask
Where does Peptaura fit among peptide suppliers?
Peptaura is our pick for buying research peptides online, including peptides made in China: a marketplace that shows vetted vendors side by side, with a certificate of analysis tied to a batch number on every listing. The pick rests on Peptaura's published catalog, testing tools and buyer protections, weighed against the criteria in this guide. It is not a tested ranking of every peptide supplier.
What should a buyer do first?
Wherever a peptide is made, each vial should trace back to a tested batch. This guide starts at the batch certificate and follows the path through independent testing, buyer protection and delivery. Settle on the compound, then compare offers batch by batch rather than brand by brand: read the certificate for the batch on sale and make sure its batch number matches the listing before you pay.
Should I always buy the lowest price per milligram?
Only after checking the batch certificate. A lower price is worth nothing if the batch fails identity or quantity, so compare prices among offers that pass the same checks.
