We're looking at a 99% pure semaglutide lyophilized powder, CAS 859216-15-2, with a molecular weight of 2611.41 g/mol — that's pharmaceutical-grade production, so you're getting tighter tolerance than most research supliers offer.

Most buyers in this space are running GLP-1 receptor studies, appetite regulation work, or metabolic pathway experiments, and they usually go with the 5mg vials for longer.

It's not great for in vivo work beyond basic stability checks because the 2-8°C refrigeration requrement means you'll need cold chain logistics sorted before ordering.


We ship form our facility, and payment is typically via T/T or wire transfer — MOQ is 10 vials (either 2mg or 5mg per vial), and we usually have stock within 20 days or so, but confirm lead time.

One thing most people don't ask about: powder can be slightly hygroscopic, so you'll want to handle it in a dry enviornment when reconstituting.

Anyway, teh documentation side is solid — our company provide COA with HPLC data and TDS on request, and we've had zero issues with customs for research-use shipments.
