Synthesis Peptides is a veteran-owned, U.S.-based vendor shipping from Las Vegas, NV. The catalog covers 40+ research compounds across GLP, recovery, growth, anti-aging, cognitive, metabolic, skin tone, and sexual health research categories, plus reconstitution solutions — with products like the BPC-157 + TB-500 blend, GHK-Cu, Tesamorelin, and GLP-3R. Alongside standard research peptide vials, the vendor also carries newer oral research peptide tablets such as 5-Amino-1MQ and SLU-PP-332. Every batch is third-party tested, and the vendor publishes a Certificate of Analysis (COA) for every batch showing the exact peptide content per vial, with HPLC purity verification shown on product COAs.
On the logistics side, Synthesis Peptides offers same-day dispatch on orders placed by 12pm PST, cold temperature-controlled and discreet unmarked packaging, shipment protection, and free U.S. shipping on orders over $250. Discount availability can change at the vendor checkout level, so always confirm the savings appear in the final order summary before completing an order.
Worth knowing before you check out: on September 22, 2026 the vendor's own storefront banner advertised "25% off sitewide with code SEPT25" — its own seasonal promotion, carrying its own code rather than ours. The banner also repeated "Free shipping on orders over $250" and "Veteran-Owned · U.S.-Based". A sitewide vendor code can out-discount a stacked affiliate code, and whether SEPT25 combines with PSTACK is not stated by the vendor, so apply each in turn, compare the order total, and keep whichever leaves the lower price. PSTACK stays the code tracked on this page.
