Price index
The cheapest place to buy each compound
Every compound priced across the top 25 ranked vendors, with the exact vial and price each store lists and a $/mg figure so different sizes compare fairly. Prices are read from each vendor's own store at a reference vial size per compound. Vendors offering a PepIndex discount code are listed first for each compound, then the rest by price; the Cheapest tag always marks the lowest listed price.

Cheapest listed price per compound
Every figure is a listed price read from the vendor’s own store at a reference vial size, divided by the milligrams in that vial. Comparing per vial instead would rank a small vial above a larger, cheaper one. A low price per milligram is worth having only alongside a certificate for the lot, which is what the evidence ranking measures.

Each price is the vial the vendor lists at the size nearest the compound’s reference vial, read from the vendor’s own store and shown per milligram against the peer median. Prices move as the market does and can lag a vendor’s current listing. The visit button goes to the vendor’s store through our tracked link, which for partner vendors is their partner link. Vendors offering a PepIndex discount code are listed first for each compound, then the rest by price per mg; the Cheapest tag always marks the lowest listed price. Partner arrangements never affect any score or rank.
Questions
How do you compare peptide sellers by price per milligram instead of price per vial?
Divide the vial price by the milligrams in the vial, then compare that figure. Vial pricing hides size: a $20 five-milligram vial costs $4.00/mg while a $32 ten-milligram vial costs $3.20/mg, so the cheaper-looking vial is the dearer peptide. Every price in this index is normalised to dollars per milligram at a reference vial size per compound, across 659 vendor prices covering 59 compounds, so vendors selling different sizes compare on equal terms.
Which vendor is cheapest for each peptide?
BPC-157: Origin Labs at $2.50/mg; GHK-Cu: Eternal Peptides at $0.370/mg; MOTS-c: Next Gen Peptides at $2.00/mg; NAD+: PeptidePlugs at $0.050/mg; Semax: GenX Peptides at $1.67/mg; Ipamorelin: Bench Grade Peptides at $3.90/mg. Each figure is the lowest listed price per milligram among the top 25 ranked vendors, read from the vendor's own store.
Is the cheapest peptide vendor the best choice?
Not on its own. Price per milligram tells you what a milligram costs, not what is in the vial. A low price is only a bargain when the vendor also publishes a third-party certificate for the lot, naming a laboratory that is not the vendor and printing the assayed mass against the label. Read the price alongside the evidence score rather than instead of it.
