Selling since 2025, GenPeptide offers research peptides online. In September, GenPeptide had 33 items across 22 compounds on sale, with nothing out of stock. GenPeptide describes its shipping as same-day shipping before 1 PM EST; 2-day/overnight available. Tirzepatide comes in four sizes, from 10 mg up to 60 mg. Its biggest lines are Tirzepatide, Retatrutide, GHK-Cu, Semaglutide and BPC-157. At checkout it takes Visa, Mastercard, Discover, crypto, Zelle and Venmo. The certificate links all lead to a single page on GenPeptide's site; the report for your lot should be listed there. GenPeptide says testing is done by a third-party lab. Alongside single vials it lists 4 bundled kits. Prices are read from GenPeptide's own product pages and converted to cost per mg, so a single vial and a kit compare fairly. PepLookup doesn't sell its products; orders go through GenPeptide's own site, for laboratory research use only.
GenPeptide is cheap on some lines and dear on others. It came in under the typical price on 15 compounds and at or over it on 7. Tirzepatide is the one to watch, at about 43% under the median. It takes Visa, Mastercard, Discover, crypto and Zelle, so most buyers can check out the way they prefer. Dispatch terms: same-day shipping before 1 PM EST. At checkout, adamdan knocks 10% off.
GenPeptide sits in the middle of the market on price. Its strongest prices were on Tirzepatide (about 43% under the median), BPC-157 (about 26% under the median) and BPC-157 + TB-500 (about 25% under the median). Bacteriostatic Water is where it falls behind, at about 50% above the median, with MOTS-c not far off at about 28% above the median. The comparison pages put it next to 84 other suppliers, so it takes a minute to check a specific compound.
