QSC Semaglutide Factory Supply High Purity GLP-1 Peptide for Research Use

You'll get the lyophilized powder in 5mg, 10mg, 15mg, or 30mg vials—we usually ship 10, and most buyers go with the 10mg for dose-response work because it's easier to reconstitute in small batches. We run HPLC on every lot, and purity comes back at 99% consistently, which is better than reagent grade for this type of peptide research.

Just a heads-up, this isn't for personal use, so anyone expecting something clinical should look elsewhere, but for lab-based metabolic or weight management studies it's pretty much standerd. Short-term storage is fine at 0-4°C, but if you're sitting on it for months or longer, keep it at -20°C and you'll get over two years of stability (check lead time on larger orders though).

We've been supplying this CAS 2023788-19-2 for a while now, and one thing you don't always think about is that the molecular weight at roughly 4813 g/mol means reconstitution volumes matter—too much solvent and the peptide can degrade faster. COA includes full HPLC traces and SDS, so batch consistency is easy to verify.

Anyway, there's a retest policy if you're not satisfied with quailty, but we haven't had many takers; basically the powder is stable enough that even if you leave it at room temp for 20 days or so it'll hold, though we don't recommend that for long term. One detail that usually catches people off guard is that the 5L drum is easier to handle if you're running high-throughput assays, but for most labs the vial format works fine.

MOQ on standard packging is 10 vials, but our company can do custom counts if you need 30mg vials specifically—just confirm lead time since that size isn't always in stock. No call-to-action here, just the info you need to decide.
