We’re responding to your RFQ for Tirzepatide, the CAS is 2023788-19-2, and we’ve got stock in the UK right now—MOQ is 10, but you can mix strengths if you need to. Purity hits ≥99% by HPLC, which is better than reagent grade for this kind of metabolic research, and it’s a white to off-white powder that looks consistent batch to batch.
The molecular weight is 4813.47 g/mol, and the formula is C225H348N48O68—basically what you’d expect for a dual GIP and GLP-1 agonist, so it’s suited for diabetes or obesity studies, not for anything in vivo unless you’ve got the right approvals. Storage is a pain, honestly: it needs -20°C and protection from light, so plan your freezer space accordingly (usually 2-4 weeks lead time if we’re out of stock).
One thing we’ve noticed is that most buyers go with the 5mg or 10mg vials for initial dose-response work, but we also offer 15mg and 30mg if you’re scaling up. Pharmaceutical grade means it’s GMP-compliant—we’ve got COAs for every batch, and they typically show 99.3% or so, though we don’t guarantee tighter than 99% without a custom spec.
Actually, the suplier mentioned that this isn’t suited for oral dosing in research—it’s an injectable formulation, so don’t plan on gavage studies unless you know what you’re doing. We usually have stock in UK warehouse, but check lead time for custom packaing; the standdard is 10 with labeling and documentation included.
Anyway, we’ve ordered 50 vials of the 10mg strength for our lab—roughly 20 days delivery, and the price came in at about £120 per vial for that quantity. It’s a solid alternative to sourcing from US suppliers, given the shipping delays we’ve seen lately.
We require a minimum of 10 vials per order, which matches the box packaging of 10 vials. You can mix different vial sizes (5mg, 10mg, 15mg, 30mg) in that same box to meet your research needs.
Yes, we supply a CoA with every batch, showing the exact HPLC purity results—typically above 99%—and confirming the identity via mass spec and NMR.
Orders are processed within 24 hours, and shipping to the UK usually takes 5–7 business days via tracked courier. We keep stock in our EU warehouse to speed things up.
Store them at -20°C in a freezer, protected from light. Each vial is lyophilized powder, so keep them sealed until use—they'll stay stable for at least 12 months under those conditions.
We can customize packaging for larger bulk orders—say, 50+ boxes—but for standard wholesale, the 10-vial box is fixed. Each vial is individually sealed, so you can open them as needed.
