Basically what you're getting is a, CAS 2381089-83-2, running at ≥99% purity verified by HPLC—and we batch-test every lot so you don't have to guess.
It's a 3855.3 g/mol peptide, C172H265N43O51, and we follow GMP guidelines for synthesis. stuff is pretty much stable for 24 months if you keep it at -20°C, protected form light. Most buyers go with the 10mg vials for metabolic studies or weight management research, but we also have 5mg if your dosing is tighter. Storage is critical, so don't leave it out on the bench. Also, we usually have stock, but confirm lead time on larger MOQs.

Not suited for anything beyond controlled lab work—this isn't a supplement, it's a research tool. That'd be a mistake.

One thing you might not think to ask: the lyophilized cake can be brittle, so let it come to room temp before reconstituting. We pack 10, and teh white powder appearance is consistent batch to batch. The molecular weight (3855.3) matters for accurate molar dosing in your assays—don't just go by mass alone.
So the tight tolerance on purity is better than reagent grade for this kind of work. You'll see it in the COA.
