A researcher running a 48-week metabolic study on diet-induced obesity models would want something that actually delivers on teh 24.2% weight reduction seen in trials, and that's where this lyophilized peptide comes in—it's pretty much the same active sequence used in those clinical programs.
We've been supplying this to labs for about a year now, and most buyers go with the 10mg vials since they're easier to split across dosing groups, but the 5mg option works fine if you're running smaller cohorts.

Purity is typically 99% by HPLC, and we include the COA with every batch—(the molecular weight sits at 3822.3 g/mol, which is consistent with full-length chain)—so you're not guessing about what's in the vial.

Storage is straightforward: keep it at 2-8°C and away form light, and it'll hold for 24 months or so, but honestly, most labs use it up within six months anyway.

It's not really suited for acute toxicity screens since the half-life is pretty long, but for chronic metabolic studies or GLP-1 receptor work, it's a solid fit.
The facility have GMP cerification, so you're getting production standerds that match what the pharma companies use, and we usually have stock on the 10mg/box format ready to ship.
