That 4813 molecular weight is part of what makes it tricky to handle—solubility can be finicky if you don't reconstitute it properly, and we usually recommend letting it sit for a few minutes after adding the bacteriostatic water.


It's a white powder, 99.9% pure by HPLC, and we run a COA before it leaves. Most buyers go with the 10mg vial, but you can order by the box of ten if you're planning a longer study. The CAS is 2023788-19-2, and the EC number is 200-001-8 if your lab needs that for documentation.

Anyway, PEG-modified lysine side chain is what gives it that extended half-life compared to some of the older GLP-1 compounds—it's not just about the GIP and GLP-1 dual agonism, which is pretty much the whole point for metabolic research. We've seen it used a lot in weight management studies, but honestly, it's also being looked at for inflammatory conditions in some early work I've heard about.

One thing people don't always ask: teh powder is hygroscopic, so keep it sealed until you're ready to use it. (Usually 2-4 weeks of shelf life once reconstituted if stored properly.) our company have fast delivrey options on this, but check lead time if you need it in a hurry—we usually have stock, but confirm.


It's not suited for anything oral, obviously—this is strictly for research use, not for human consumption. 20 days or so form order to delivery if we're shiping internationally, give or take a few days for customs.
Yes, we provide a full CoA with every batch. It shows the HPLC purity and other specs so you can verify the 99.9% before use.
We ship from a single vial upwards — there's no strict MOQ. If you need just 1 vial or several boxes, we can handle it.
We offer express shipping options that typically deliver within 2–5 working days to UK addresses, depending on the service you choose.
Absolutely. Store it in a cool, dry place away from light and moisture. We also include storage instructions with your order.
Yes, that EC number is correct for Tirzepatide and can be used on shipping documents. We'll include it in the paperwork to help with clearance.
