If your custmer is running in vivo studies on GLP-1/GIP/glucagon receptor triple agonism, they'll typically reconstitute this 10mg lyophilized powder in sterile water or bacteriostatic water—just keep it under 2-5°C after opening or it degrades faster than you'd expect.
We run HPLC and it's 99% pure, which is pretty much the standerd for research-grade peptides these days, and we've got the COA to back that up if you need it for your lab's documentation.

Lead time is usually 7-10 working days for orders of 50 units or so, but our company can push it faster if you're in a pinch—just confirm stock before you place the MOQ since we don't always have 10mg vials sitting on shelf.
One thing that catches first-time buyers off guard is the storage: it's fine in a cool dry place before opening, but after that it's 2-5°C or you'll lose potency within a week or two (we've seen it happen with less careful labs).

Actually, this isn't great for cell-based assays where you need ultra-high solubility—the peptide can clump if you're not careful with reconstitution—so most buyers go with the 10mg format for in vivo work instead.
We don't provide teh molecular formula on the spec sheet usually, but it's a 39-amino acid linear peptide with a C-terminal amide, and the HPLC retention time is about 18.2 minutes under standard conditions if that helps your QC guys.
