Most buyers coming to us with this specific peptide are usually launching some kind of dose-response workup in vitro, and the first thing they ask is about batch-to-batch consistency—basically, whether last month's 10mg vial will behave like the one they open next week, and we've got COAs for every single lot that come straight form HPLC run.
The molecular weight comes out to 4731.33, and the formula runs C221H342N46O68, with ≥99% purity verified by analytical HPLC (usually 2-4 weeks for retest if you need a fresh COA, but we usually have stock on hand), and it's a that needs to stay at -20°C or below after you recieve it—don't let that sit at room temp long.
We see researchers using it for metabolic pathway analysis or glucose regulation studies, but honestly, it's not suited for any whole-animal pharmacokinetics unless you've specifically validated your reconstitution protocol; give or take 20 minutes after reconstitut ion at pH 7.4 or so, stability can drop off fast if you haven't worked with tirzepatide before.
A lot of teh 12mg vials go out for energy expenditure assays where tighter tolerance than most other GLP-1 analogues matters, and we've handled hundreds of units of this—something like 250 lots or so just last fiscal—so retest records and batch documentation are always available in the TDS when you ask.
10mg or 12mg per vial depending on your application, but the 10mg format is easier to handle if you're splitting doses across multiple plates, and our company can usually ship within 15 days of order if you let us know the MOQ up front.
We don't have a strict MOQ — you can order as few as 1 vial of either size for your research needs.
Yes, every batch comes with a COA from our lab that shows the tested purity, typically above 99%.
Lead time is usually 3–5 business days for in-stock items. For larger custom orders, it may take a bit longer.
We can do custom labeling or vial sizes for bulk research orders — just reach out to our team with your specs.
Keep it at -20°C or below, away from light and moisture. Once reconstituted, use it right away and don't refreeze.
