I found a current public QSC catalog, but there’s an important authenticity wrinkle. The live QSC price-list page currently indexed is: QSC Price List. It has warehouse, product, SKU, price, and stock fields, and QSC’s site was crawled within the last day. Some current 10-vial kit prices I could directly verify from that catalog: Peptide Per vial 10-vial kit Retatrutide 5 mg $200 Retatrutide 10 mg $240 Retatrutide 30 mg $330 Retatrutide 60 mg $500 Tirzepatide 5 mg $190 Tirzepatide 10 mg $200 Tirzepatide 30 mg $250 Tirzepatide 60 mg $360 Semaglutide 10 mg $190 Cagrilintide 10 mg $280 BPC-157 10 mg $200 TB-500 10 mg $270 GHK-Cu 50 mg $190 Ipamorelin 10 mg $220 Tesamorelin 10 mg $310 MOTS-c 10 mg $210 Semax 10 mg $210 Selank 10 mg $190 These appear to be public storefront prices, not necessarily QSC's lower rep/wholesale China pricing. One thing to be careful about: there are a lot of QSC impersonation/copycat domains. QSC's current site explicitly says domains such as qingdaosigmachems.com, qingdaosigmachemical.com/.net, and qingdaosigma.com are impersonators. Finnrick independently flags QSC's brand-authenticity/copycat risk as high, and Peptigraph also warns that scammers are using QSC's identity. So I would not use the February 2026 “Complete Product Pricelist” PDF from qingdaosigmachems.com that Google surfaces—it appears to be associated with one of the disputed/lookalike domains. If you want, I can dig specifically for the latest QSC China/rep price sheet—the type with the much cheaper factory prices and separate USA/Canada/EU/Australia warehouse tabs—rather than the public retail catalog.
