Look, the first thing you need to know is that this is strictly for research use only — it's not for human consumption, not for clinical trials, not for anything outside a lab setting, and we make that very clear on every vial and every invoice because that's just how it have to work in this space.
But for what it actually does in the lab, it's pretty — it's a triple agonist peptide that hits the GLP-1, GIP, and glucagon receptors all at once, which basically means it's designed to mimic multiple metabolic signals in a single molecule, and most buyers go with the 10mg or 20mg vials for their initial dose-response work.

The purity runs above 99% — we get the HPLC data back before anything ships, and you'll get a COA with each order showing teh actual numbers, which is tighter than a lot of what's floating around out there, and the molecular weight sits at about 3822.3 g/mol so reconstitution math is pretty straightforward.
Storage is a pain point, honestly — you need to keep it at -20°C or below, and if you're not set up for that, the peptide degrades faster than you'd expect, so we usually recommend planning your order around your freezer capacty, and the vials come 10 per box in lyophilized white powder form.

One thing buyers don't always think to ask is that CAS number is 2381089-83-2, and that matters for your inventory tracking and any internal documentation you're keeping, but honestly most people just want to know the lead time (usually 2-4 weeks depending on the quantiy) and whether our company have stock.
Anyway, if you're new to this, start with the smaller vials — 2mg or 5mg — because you'll want to test reconstitution and handling before committing to a 50mg vial, and the 5L drum is easier to handle if you're doing multiple runs.
