Got your email—we've been moving quite a bit of this batch recently, and it's the 5mg per vial format that most buyers go with for titration studies, though CAS is 2023788-19-2 if you're cross-referencing with your records.
Basically, it's a dual GIP/GLP-1 agonist with a molecular weight just over 4800 and HPLC purity at 99% or better, which matters more for consistent dosing than some realize. We usually have stock, but confirm lead time if you need more than 50 vials.
The white powder stores fine at -20°C for over two years, but what it does is really shine in metabolic research where you want that dual receptor binding—better than a single GLP-1 agonist for certain protocols. It's not ideal for acute studies where you need rapid onset, though.
Also, one thing a buyer might not think to ask: the 5mg/vial packaging means you'll need to reconstitute carefully, as the volume per vial is tiny (check your equipment). Most researchers go with 1mL of bacteriostatic water for reconstitution.
We ship under HS code 2934.99.9001, and teh COA is included—HPLC verified—so you've got traceability. Lead time is roughly 15-20 days or so, depending on your location.
Anyway, if you're comparing with other supliers, the tolerance on this is tighter than most reagent-grade options, which is why we see repeat orders form diabetes research labs.
We typically require a minimum order of 10 vials, but we can discuss smaller quantities for first-time buyers or research trials.
Yes, we include a CoA with every batch that reports the ≥99% HPLC purity, molecular weight, and other specs you see listed.
Keep them at -20°C for long-term storage. If you're using them within a month, 2-8°C is fine. Avoid freeze-thaw cycles, and they'll last over 2 years.
We can, but there's a minimum of 100 vials for custom fill sizes. The standard 5mg/vial is our stock option for faster shipping.
Yes, that HS code is accurate for Tirzepatide powder under nucleic acids and their salts, and it's been used successfully for shipments to the US, EU, and Asia.
