Peptide price statistics

Numbers computed from PeptideCompare's own data: prices read from vendor websites, independent lab scores and the research library. Every figure links back to the page it comes from. Figures as of November 14, 2026; they change with each price refresh.

Price per mg for the 40 most widely sold peptides

Cheapest and median price per milligram among independently tested vendors. "Median vs cheapest" shows how much more the typical listing costs. "Lab report" is the share of vendors selling the peptide that publish a readable COA for it.

Where shopping around saves the most

Peptides sold by at least five tested vendors, ordered by the gap between the median and the cheapest price per mg. Large vials and multi-vial kits pull the cheapest figure down, so check the size on the price guide before comparing.

Listings and prices by category

Median price per mg is the middle of each compound's own median; categories mix compounds studied at very different amounts, so it describes the market, not value.

Research behind the compounds

101 of the 172 single-name products with live prices have a graded review in the research library: 16 graded A (strong human evidence), 35 graded B, 32 graded C and 18 graded D (little or no evidence for the exact compound). What the grades mean.

Prices are advertised prices before shipping, with unconditional coupon codes applied where one exists. A price per mg compares cost, not effect. See how we collect and check the data, the vendor ranking and the side-by-side comparisons.

Questions about peptide prices

How much do research peptides cost?

It depends on the compound. Among widely sold peptides, GHK-Cu starts at USD 0.019 per mg at the cheapest independently tested vendor, with a median listing of USD 0.450 per mg. The table on this page lists the cheapest and median price per milligram for the most widely sold peptides.

Why do peptide prices vary so much between vendors?

Across peptides sold by at least five tested vendors, the median listing costs 5.0 times the cheapest one. Vial size, kit quantity, shipping origin, testing costs and brand all move the price, which is why PeptideCompare compares cost per milligram instead of sticker price.

How many peptide vendors publish lab reports?

For 24% of vendor and peptide combinations in our data, the vendor publishes a readable lab report (COA) for that peptide. 10 vendors are banned from the site for fake or doctored lab reports.

Where do these statistics come from?

Prices are read from each vendor's own website, lab scores come from independent tester Finnrick and vendor-published reports we reviewed, and research grades come from the papers summarized on each research page. How we work explains each step.
