Pharmaceutical Grade QSC Tirzepatide Manufacturer - 99.9% Pure Peptide

We’ve been seeing demand for this dual agonist for a while now, and the 99.9% purity on the COA was the deciding factor—it’s better than reagent grade for this kind of metabolic work, especially when you’re running that can’t tolerate impurities from lower-grade batches.

The CAS number is 2023788-19-2, and the molecular weight runs about 4813 g/mol, which is typical for these larger peptides; we’ve got the C225H348N48O68 formula on file if anyone needs it for their mass spec calibration, though (confirm if you need the exact EC number 200-001-8 for your import docs).

It’s pretty much a, and you’ll want to store it at -20°C right away—don’t leave it at room temp for more than a day or so, or you’ll lose activity. Not suited for anything beyond research use, obviously, since it’s not pharmaceutical grade for human trials.

Most of our clients in metabolic studies are using it at the 5mg or 10mg range per vial, depending on their protocol, and the packaging we ordered is 1kg in an aluminun foil bag, which is what we usually stock for these. If you need 25kg drums or custom split, the suplier can do that, but lead time jumps to about 20 days or so.

Also, one thing that caught me off guard last time—the PEG modification on lysine side chain gives it better water solubility than the native incretin peptides, which means you don’t have to fight with solubility buffers as much during reconstitution, but it also means teh half-life is extended, so your dosing intervals in the study need to account for that.
