QSC (qscpeptide.com) stocks all major Longevity compounds: GHK-Cu, Epitalon, NAD+, Humanin, Pinealon. 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 Longevity compounds Peptide Sciences had?
Yes — QSC carries all Longevity 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.
