So your client's lab is running those metabolic pathway studies where they need a consistent GLP-1/GIP dual agonist for in vitro binding assays—that's exactly what we handle daily, and we've shipped to dozens of R&D teams doing the same thing.
We're talking ≥99% purity, verified by HPLC, and the powder comes lyophilized in 10mg or 15mg vials (10 ) so you can reconstitute exactly what you need without wasting materail—most buyers go with the 10mg vials for smaller runs.

Storage is pretty straightforward: keep it at -20°C, and it'll hold stability for 12 months or so, but we usually have stock ready to ship within 3-5 business days after payment clears, give or take depending on your order size.

Documentation is all there—COA, HPLC chromatogram, MSDS, and we can provide GMP certifictes upon request, though the CAS number (2023788-19-2) is what most procurement teams want on packing list for customs clearance.

Payment terms are typically T/T or wire transfer for first-time buyers, but our company can discuss L/C for larger volumes—MOQ is 10 boxes (100 vials total), and shippng is via FedEx or DDP if you need door-to-door with full traceability.
One thing—this isn't suited for oral formulation work as-is because the peptide degrades in the GI tract, so your client's pill idea would need a delivrey system, but for injectable or research-grade powder, it's better than reagent grade for this specific appliction.
