Peptide Prices
Compare prices per milligram from trusted, COA-verified vendors. Top vendors shown for each peptide — ranked by price after each vendor's discount code, not list price.
71 peptides6 COA-verified vendors4,734+ price observationsUpdated
How we measure.We capture each recommended vendor's public list price daily and normalize to price-per-milligram ($/mg = price ÷ mg per vial), then apply that vendor's published discount code to get the price you actually pay. Vendors are ranked on that post-code figure; the list price is shown struck through beside it. Every listed product has a COA our team has verified. Placement on /best reflects our vendor scoring and commercial partnerships. Full methodology. Maintained by The Peptide Catalog Team.

How we collect price data
- Which vendors
- Vendors we currently list (our recommended set, plus a few named vendors on specific peptides where few others stock it). On a buying guide, the market snapshot counts exactly the vendors that guide lists for that peptide.
- How $/mg is calculated
- The price of one vial in US dollars divided by the milligrams in it. Single vials only: multi-vial kits and bulk-quantity pricing are left out of medians. Injectable vials are compared with injectable vials; sprays and capsules are excluded unless a peptide is only sold that way. Euro prices are converted at a fixed rate. IU-dosed compounds (such as HCG) are shown per vial instead.
- List vs after-coupon
- List price is the vendor's price before any code. After-coupon applies the discount from our partner code or link for that vendor. It excludes shipping, bulk discounts and limited-time sales. Lowest and median figures are calculated separately for each basis, so the lowest list price and the lowest after-coupon price can come from different products.
- How often
- Prices and stock are re-checked automatically once a day. Vendors can change prices between checks; each snapshot shows the time of its most recent check.
- Stock and stockout rate
- In stock means the vendor's product page showed the item as available at our last check. We keep a log of price and stock changes; the 90-day stockout rate is the share of offer-days in the past 90 days that tracked offers spent out of stock.
- Trends
- The 30- and 90-day trend compares the median list $/mg today with the median for the same products at the start of the period. Any figure without enough history behind it (fewer than three comparable products, or a log that does not reach back far enough) is hidden rather than estimated.
- COA verification
- Our team reviews the certificate of analysis posted for each listed product and confirms it by looking up the report ID on the third-party testing lab's own site. Every listed product has a COA our team has verified.
