Someone running metabolic research will reconstitute this for dosing studies, usually with bacteriostatic water, and they'll want to know peptide content is consistent across the vial.

2, we supply it as a white powder in 10mg vials, and the purity is 99% by HPLC—better than reagent grade for this kind of work.

CAS 936544-53-5, molecular weight 695.9, and it's a GLP-1 receptor agonist, so it's not suited for anything outside lab use.
Storage is pretty straightforward: keep it in a cool, dry place and it'll hold for 2 years or so.

The vials ship with a COA, but we usually have stock, though confirm lead time if you need more than 50 units at once.

One thing you'll notice handling it is teh powder is fine and tends to cling to the vial walls slightly, so gentle reconstitution matters.
