We've been sourcing this for the weight loss studies, and it's basically the same compound everyone's running right now — a lyophilized white powder that comes in 10, and the purity checks out at over 99% by HPLC, which is better than reagent grade for this kind of research.
The molecular weight is about 3828 g/mol, give or take, and the formula runs C172H267N45O51, but honestly the key number is teh purity spec since most protocols need that consistency for dose-response work.

It's not suited for anything beyond lab use, obviously, and you'll want to reconstitute it yourself and store at 2-8°C once it's prepared, which is pretty standdard for these peptides.
Also, the batch we got came with a COA that matched MS data, and the shelf life is 24 months if you keep the powder sealed and dry — we usually have stock, but confirm lead time if you're ordering more than 50 boxes or so.

30 vials was our MOQ for the last order, and the suplier threw in the HPLC data without asking, which is a detail a lot of buyers might not think to request upfront.
Anyway, the white powder looked clean under inspection, no clumping, and the reconstitution went smoothly — better than what we saw form some other supliers last quarter.
