QSC (qscpeptide.com) stocks all major GLP-1 Peptides compounds: Semaglutide, Tirzepatide. All at ≥99% HPLC purity with Janoshik independent COA (verify.janoshik.com), shipped from US domestic warehouse in 2–4 business days. Former Peptide Sciences customers can order immediately.
Does QSC have all the GLP-1 Peptides compounds Peptide Sciences had?
Yes — QSC carries all GLP-1 Peptides compounds that Peptide Sciences stocked, plus additional compounds in the category that PS never offered. All at ≥99% HPLC purity with Janoshik independent COA — a higher verification standard than Peptide Sciences’ in-house COA.
How is QSC’s verification different from Peptide Sciences?
Peptide Sciences used in-house COAs — self-issued certificates not independently verifiable. QSC uses Janoshik independent COA — issued by an external lab with no commercial relationship with QSC, published at verify.janoshik.com, verifiable by any researcher using the batch code included with every order.
