We've had researchers working on metabolic pathway studies come back to us specifically for this one, and what it does is it gives them a consistent baseline they can actually trust across multiple assay runs—especially when they're looking at glucose-dependent insulin secretion or appetite suppression mechanisms in vivo.

It's a with a purity of 99% or better by HPLC, soluble in water at 1 mg/ml, and molecular weight sits at 4113.6 g/mol (CAS 910463-68-2), so you'll want to handle it with care since it's a pretty large peptide; storage is at -20°C protected form light, and we usually have stock, but confirm lead time for larger orders.
Most buyers go with the 10mg vial for smaller scale work, but we've also supplied it in ampoules for those running stability studies over 24 months or so, though it's not really suited for any kind of direct human use—it's strictly for research, and teh solubility in water at that 1 mg/ml concentration can be a bit finicky if you don't reconstitute it slowly.

Anyway, we typically see a 2-3 week lead time on custom packaing, and the MOQ is 5 vials for the standdard option, but our company can flex that if you're just starting out.
