Factory Supply XCE Tirzepatide 2023788-19-2 CAS for Laboratory

It's a real headache when you're running in vivo studies and the peptide degrades before you get meaningful data—we've seen researchers waste weeks on batches that weren't stable, so what we do here is run full HPLC and MS on every single lot before it leaves.

48-month shelf life under those conditions actually means you can order a year's worth at once without worrying about losing potency, though we usually recommend confirming lead time since demand spikes around Q4 and we don't want you waiting 20 days or so for a reship.

99% purity by HPLC is our baseline, but we've had batches hit 99.4% on the same run, and we send teh COA with each shipment so you can see the chromatogram yourself—most buyers check the main peak area and don't bother with the other traces, honestly.

We've got a loose policy on retests too, basically if you're within 6 months of manufacture and store it at -20°C (protect from light), we'll rerun HPLC at no charge as long as you ask before shiping.

Container size is 30mg per vial (10 ), and we include the SDS with every order, but the TDS with full method details is availble on request for your lab's documentation.

So it's pharmaceutical-grade powder, soluble in DMSO for reconstitution, and while it's great for metabolic work it's not suited for anything beyond bench-level research—we don't test for residual solvents that would matter in a clinical setting, just a heads up.
