Which listings are left out?
Vendors below a metascore of 70, vendors you can only order from by message, listings marked out of stock, prices older than 14 days, and prices far outside the range other vendors charge for the same peptide (usually a vial-count mistake or a whole kit priced as one vial).
How current are these prices?
Prices are read from each vendor's own website; the newest on this page was checked on 13 Nov 2026. The page is rebuilt with every price refresh, and a listing drops off once its price is more than 14 days old. Check the vendor's page before ordering.
Do affiliate links change the ranking?
No. The tables are sorted by price only. Some Buy links are affiliate links that may earn PeptideCompare a commission at no extra cost to you.
