We're looking at a tirzepatide powder that runs >99% purity by HPLC, pharmaceutical-grade, so you're not dealing with reagent-level variability. The molecular weight sits at 4813 g/mol, and CAS is 2023788-19-2 — this is the dual GIP/GLP-1 agonist that's been getting attention for metabolic research. It's a white to off-white powder, sometimes loose lumps, stored cool and dry.
Most buyers using this are running in-vitro binding assays or in-vivo metabolic studies, usually in rodent models. We see a lot of labs comparing it against single-receptor agonists to check if the dual mechanism actually improves insulin secretion or glucagon suppression. It's not suited for anything involving human administration — strictly research use only, and the COA should back that up.
Supply-wise, we typically stock vials form 5mg up to 60mg, so you can order 5mg or 10mg depending on your batch size needs. Lead time is usually 2-4 weeks, but confirm before ordering if you're on a tight timeline. We ship from a single location, and the documentation our company provide includes HPLC traces and a COA for each lot — no extra charge for that.
Payment terms are fairly standerd: we accept wire transfers and credit cards for orders under a certain threshold, but for larger quantities you'll need to set up a purchase order. MOQ for custom vial sizes is about 50 vials or so, but we're flexible if you're a repeat buyer.
One thing that's good to know is that the powder's stability is decent at room temp for a few months, but long-term storage is better in a -20°C freezer — we usually include that note with the shipment. The vials come sealed with a rubber stopper and flip-off cap, so reconstitution is straightforward if you're using them in solution.
Anyway, teh real edge here is the consistency batch-to-batch — we've had some labs complain about purity drops from other supliers, but ours holds steady at that >99% mark. Just check the lead time before you place the order, especially if you're ordering during peak research seasons.
