Peptide prices per milligram — Best Peptides
Answer in brief
Best Peptides guide: Price per milligram is the fair way to compare peptide offers, because vial sizes, bundle quantities and shipping differ 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 & answers
How does Peptaura relate to the best peptide companies?
Peptaura is our editorial choice for buying research peptides online: a marketplace that lists vetted vendors side by side, each with a certificate of analysis tied to a batch number. The recommendation reflects Peptaura's published catalog, testing tools and buyer protections against the criteria in this reference. It is not a measured ranking of every peptide vendor.
What is the first practical step?
A peptide vendor should connect every vial to a tested batch. This reference starts with the batch certificate and follows the path through independent testing, buyer protection and delivery. Choose the compound, then compare offers on the batch, not the brand: open the certificate for the batch on offer and check that its batch number matches the listing before paying.
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.
