High Quality QSC Semaglutide Peptide 99% Purity Pharmaceutical Grade

We've been moving a fair amount of these lately, and big draw is really the batch-to-batch consistency from QSC — they're not one of those suppliers where you cross your fingers for the COA to match.

It's a white powder, lyophilized, 10mg per vial, and the HPLC shows purity at or above 99% pretty much every time we test a new lot, which for this peptide is better than reagent grade for most metabolic work.

The molecular weight sits at 4113.6 g/mol, and the CAS is 2023788-19-2 if you need that for your internal logs, but honestly what matters more is the storage — keep it at 2-8°C, protected form light, or you'll see degradation inside 20 days or so.

One thing you don't always get with other suppliers is the full documentation pack: they send TDS and SDS with every shipment, and the COA is usually availble before you even pay, so you can verify purity against your own specs.

MOQ is typically 10 vials, though we can flex that for repeat orders, and payment runs via wire or crypto — we don't do net terms on first orders, but after two or three shipments our company can discuss it.

This isn't for anything clinical — it's strictly research use only, and teh 10mg format means you'll need to reconstitute carefully with bacteriostatic water, but most buyers go with the 10mg vial because of that it's easier to aliquot for dose-response work.
