So you've been searching for tirzepatide for what feels like forever, and honestly, the inconsistency out there is a nightmare — we've all seen the batches that claim 99% and come back with HPLC showing 94%, which basically wastes weeks of work.
2023788-19-2 is the CAS you'll need for customs, and we're talking about a 4813 molecular weight with a C225H348N48O68 formula, pharmaceutical grade with a 99% purity on every COA our company provide, and we typically run 20mg or 10mg per vial depending on your protocol, but the 10mg is what most buyers go with for metabolic studies.
What it does is hit both GLP-1 and GIP receptors — that dual agonist mechanism is what separates it from the single-target peptides, and we've had researchers tell us the binding affinity holds up better than reagent grade stuff for, though it's definetly not suited for any in vivo work without proper ethics clearance, obviously.
Tighter tolerance than most suppliers offer, actually, and we know because we've had customers come to us after getting burned on purity claims; one thing you might not think to ask is that we usually stock the vial as lyophilized powder, and reconstitution is pretty straightforward with bacteriostatic water, but let me know if you need the SDS for handling.
OEM is possible if you need custom labeling or a different fill volume, but the MOQ for that is roughly 50 vials or so — otherwise we ship from our UK warehose in about 2-4 weeks, and we always include COA with each order, though our company can't guarantee exact lead times during holiday rushes.
Anyway, we've sold a lot of this to university labs and private researchers, and the feedback has been solid, but if your appliction is purely analytical standerd work, this holds up better than most intermediates on the market.
We typically require a minimum order of 5 vials for this product, but if you need less, just reach out and we can discuss.
Orders usually ship within 3-5 business days after payment confirmation. Delivery to the UK takes about 7-12 days depending on customs.
Yes, we include a COA with every batch, showing the HPLC test results that confirm the 99% purity grade.
Store the vials in a cool, dry place between 2-8°C, away from light. For longer storage, keep them in the freezer.
We can discuss custom vial sizes or bulk packaging if you have a specific need, but the standard is 10mg per vial in a sealed container.
