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.
