So we’ve got several labs asking about bulk tirzepatide now—basically same ones who were testing semaglutide a year ago, and most of them are running long-term metabolic assays or obesity model work, which means they need consistent supply across multiple batches rather than just a one-off gram.

2023788-19-2 is the CAS, and the molecular formula runs C225H348N48O68, so it’s a hefty peptide—around 4.2 kDa—which directly affects how you handle it in solution (don’t vortex it, we’ve seen aggregation if you do), and we’re shiping it as a lyophilized white powder at 99.9% purity confirmed by HPLC.

Each vial holds 10mg (which is actually pretty standerd for receptor activation assays), and teh MOQ is 10 vials, but most buyers go with 50 or 100 vials per order anyway because the per-unit price drops noticeably at that volume—usually 4-6 weeks lead time for batches over 500 vials, though our company have stock for smaller quantities (check with me before ordering if you’re under a deadline).
What it does is it’s a dual GIP/GLP-1 receptor agonist, so it pulses both incretin pathways, and what I’ve heard form a few groups is that this gives tighter glucose control in their diabetic mouse models than the single-target peptides alone—but it’s not suited for chronic dosing studies longer than 8 weeks without careful degradation checks, since the PEG modification on the lys side chain can shift clearance rates.

Storage is 2-8°C in the dark, and the powder stays stable for about 18 months or so under those conditions, but once you reconstitute it, you’ve got maybe 72 hours tops at 4°C—pretty much every buyer asks about that, and we include a COA with each shipment showing the HPLC traces and mass spec confirmation.

And one thing that’s caught people off guard is the hygroscopicity—leave the vial open for more than 10 minutes in normal humidity and you’ll see clumping, so we recommend reconstituting immidiately after opening and not re-storing the dry cake once punched.
We guarantee 99.9% purity by HPLC. A Certificate of Analysis is included with every order, showing the exact purity, identity, and residual solvent levels.
MOQ is just 10 vials. For stock items, lead time is 3-5 business days. Larger custom orders may take 7-10 days depending on batch size.
Store at 2-8°C, protected from light. Once reconstituted, keep refrigerated and use within the timeframe specified in your protocol. Avoid freeze-thaw cycles.
Yes, we can adjust vial sizes or box quantities for bulk orders. Just let us know your preferred specs, and we'll work out the pricing and lead time.
Absolutely. We supply a COA, MSDS, and a statement confirming the product is for research use only. Additional export or customs docs can be arranged on request.
