Price per mg or price per vial?
Vial sizes differ from one listing to the next, so the sticker price says little on its own. Dividing each price by the stated milligrams gives a $/mg figure that can be compared across stores and sizes, which is how every number above is built. To turn a $/mg figure into a total for an amount in mg, use the peptide cost calculator.

Questions about peptide cost
How much do peptides cost per mg?
As of 10 Oct 2026, the median listed price across the 41 peptides we track is $6.90/mg, taking each compound's own median $/mg. The middle half of compounds sits between $4.799/mg and $9.65/mg, and the range runs from $0.0536/mg (Glutathione) to $152.95/mg (Follistatin). Prices are single-vial listings from US vendors, ex-shipping, refreshed nightly.
How much does a vial of a peptide cost?
For each compound's most commonly listed vial size, the median listed price per vial is $65.00 across 41 compounds as of 10 Oct 2026; the middle half runs from $50.00 to $84.00. Vial sizes differ by compound, so a vial price is not comparable across compounds: compare $/mg instead. The table on this page lists the vial size behind each figure.
Are peptides expensive?
This page does not rate prices as high or low. For scale, as of 10 Oct 2026: 4 of 41 compounds have a median under $1.00 per mg, 29 sit between $1.00 and $10.00, and 8 are over $10.00. The highest compound median is 2854 times the lowest, so the answer depends entirely on which compound and which vial size you look at.
Why do peptide prices differ so much?
They differ between compounds, between vial sizes and between stores. Within a single compound, the highest comparable listing is a median of 11.8 times the lowest listing across the 41 compounds here (10 Oct 2026). We report the median instead of an average because one mislabelled or bulk listing can distort an average.
What is included in these prices?
Regular listed product prices in US dollars for single-vial, single-compound listings from US vendors. Shipping, temporary sale prices, multi-vial packs, blends, topical products and stores outside the US are not included. See how $/mg works for the full rules.
How often are the figures updated, and how far back do they go?
Listed prices are read nightly and the page is rebuilt from the same data as each compound's own price page. The public price history on this site covers the last 90 days; each compound page shows its dated daily medians.
