If you're running a GLP-1 receptor agonist study and the standerd batch-to-batch variability is throwing off your, we've seen this 99%+ HPLC-tested white powder hold tighter than most. The CAS is 2381089-83-2, and it's basically a 40+ amino acid chain—C223H343F3N46O70—so you'll want to verify your reconstitution protocol with a COA before scaling.
It's not for every project though—if you're chasing acute appetite suppression in a quick-turnaround screen, the half-life profile here (roughly 5 days or so) might actually complicate your timeline. Most buyers go with the 10mg vial for longer-term metabolic work, but we've also had labs order 2mg or 5mg when they're titrating doses across multiple cohorts.
Storage is straightforward: -20°C, dry, dark—and we mean dark, as in don't leave it on the bench under a fluorescent light for 20 minutes. Shelf life is over 2 years if you keep it sealed, though we usually have stock ready to ship in 2-4 weeks (check lead time for bulk orders, as we do run out sometimes).
4. Teh purity spec isn't just a number—above 99% by HPLC means fewer degradation peaks showing up in your LC-MS traces, which is what the in vivo guys care about when they're tracking metabolite formation. We don't include a TDS in every shipment unless you ask, but the COA is standard.
One detail we don't always mention upfront: powder can be slightly hygroscopic, so if your lab is in a humid climate, reconstitute in a glovebox or at least under a dry nitrogen stream. It's not a dealbreaker, but it's something you'll notice after handling a few vials.
We typically require a minimum of 10 vials per order, but you can mix different vial sizes (2mg, 5mg, or 10mg) to meet that. If you need less, just reach out—we might be able to accommodate smaller research batches.
For stock items, orders usually ship within 3-5 business days after payment clears. International delivery can take 7-14 days depending on customs, but we can provide tracking once it's on its way.
Yes, every batch comes with a COA from our lab showing the >99% HPLC purity result. If you need a third-party test or specific documentation for your research, just let us know and we can arrange that.
The -20°C storage is for long-term stability, but during transit we ship with ice packs in insulated packaging to keep it cool. Once received, store it in a freezer at -20°C, dry, and away from light to maintain the >2-year shelf life.
We offer standard 2mg, 5mg, and 10mg vials for the Tirzepatide. Custom sizes are possible for larger research orders—just contact us with your requirements and we'll see what we can do.
