We're seeing 99% purity consistently on these vials, and the 10mg size is what most labs go with for their initial runs — the 2mg is really just for testing solubility or small-scale work, and the 5mg sits in between, usually for dose-finding studies.
It's a white powder in a sealed vial, and after opening you'll need to store it at 2-8°C, which is pretty standerd for peptides like this — we usually have stock on the 5mg and 10mg, but the 2mg can take 20 days or so to restock if we're out.

Basically, what it does is act as a dual agonist for GIP and GLP-1 receptors, which is why it's getting attention for weight loss research — clinical data shows average reductions of 15% at 5mg, 19.5% at 10mg, and 20.9% at 15mg over 72 weeks, though that's for the therapeutic form, not this research grade.

The CAS is 2023788-19-2, and the molecular weight comes to about 4813 g/mol — it's a large peptide, so handling it requires some care with reconstitution, and it's not suited for direct human use, just in vitro or animal work.

One thing you might not think to ask: the EC number is 200-001-8, and while it's pharmacy grade, the COA typically shows tighter tolerance than reagent grade for this — our company can provide HPLC data on request, but confirm lead time if you need it fast.
Most buyers order the 10mg vials in cartons of 10 or so, and we ship in cardboard packging with the TDS and SDS included — anyway, that's teh gist of it for now.
