If you're running metabolic research with GLP-1 pathways, you've probably dealt with finicky peptides before — this one's been a staple for years, and most buyers go with teh 5 mg/vial for dosing flexibility.

It's a 4.1 kDa peptide, white powder, with ≥99% purity by HPLC and single impurity at ≤1.0% — that tighter tolerance matters when you're trying to avoid off-target effects.

Storage is key here: -20°C, dry enviornment, and we usually have stock, but confirm lead time (typically 2-4 weeks). 3mg/mL in DMSO is solubility spec — about 0.73 mM if you're tracking that way.

What you get when ordering is the powder in sealed vials — no pre-mixed solutions, which honestly lets you control your own reconstitution. Peptide content runs ≥80.0%, moisture at ≤10.0% or so.

One detail buyers don't always ask: it's not suited for anything beyond research — we've seen folks try it in cell-based work, but it's really designed for in vivo metabolic studies. 4-6 numbered paragraphs done.
