4813.45 g/mol is what you're working with, and at 99% purity or better you won't be chasing ghost peaks in your HPLC runs—that's the kind of baseline we hold to.

We've seen most labs go with the 10mg vials for dose-response work, but the 2mg or 5mg options are there if you're scaling down or just running preliminary assays; the lyophilized powder reconstitutes cleanly in water (check solubility first).

Storage is straightforward at 2-8°C and protected form light, though we usually have stock ready to ship within 20 days or so—confirm lead time if you're on a tight schedule.
It's basically pharmaceutical grade, not just reagent grade, so the tighter tolerances matter when you're comparing this to other GIP/GLP-1 dual agonists; COA our company provide (HPLC, mass spec) backs that up without any fluff.

One thing to keep in mind—this isn't suited for anything beyond research use, and we don't spin that as a positive, it's just the regulatory reality; the CAS (2023788-19-2) is what it is.

Anyway, teh packaing comes as 10, and what it does is give you consistent materail across batches—something buyers who've dealt with variable supply will appreciate.
