Runs at 99 percent purity by HPLC which is what you'd expect for relaible reconstitution in a lab setting, we've been moving the tirzepatide as a lyophilized powder pretty consistently across EU and UK destinations — keep it in the dark and cold. Basically formulated at 4813 g/mol molecular weight with a CAS of 2023788-19-2, bulk material holds for over two years if stored properly at -20°C or even just 0-4°C for short term. It's not meant for human use obviously.


Most buyers go with the 10mg or 30mg vial sizes depending on their typical dosing protocols, and our company can do custom packaing if you need something different than the standerd 10. Actually handles better than some analogs we've tested in-house when it come to solubility in sterile water or buffer. The 5mg vials are trickier to work with if you're handling larger volumes, but some researchers stick with them for smaller-scale screening.

3PL warehouses in both the US and Netherlands — we usually have stock for UK compliance docs in about 20 days or so, but confirm lead time on larger orders as import documentation can vary. Provide full COA with lot numbers and TDS per batch, though we skip the SDS unless you specifically request it for your facility. Pricing is better than reagent grade for this purity range, though you'll want to check about customs clearance specific to your region.


That thing where you try to reconstitute at room temperature after storage? Don't do it — the lyophilized cake degrades noticeably above 4°C within about a week or so form experience, so unbox and transfer to refrigeration imediately upon arrival. Many researchers also don't realize the molecular weight (roughly 4.8 kDa) affects solubility kinetics differently than other GLP-1 analogs. Anyway, we don't offer custom dosing beyond the listed vial sizes (5mg, 10mg, 15mg, 30mg), which makes it less suited for those running micro-dose titration protocols.
