Buy Tirzepatide CAS 2023788-19-2 | High Purity 99% Pharmaceutical Grade

It's for research use only, not for human consumption or clinical application, which is the first thing you need to know if you're looking to stock it. That said, what it does is simulate teh dual agonist action of GIP and GLP-1 receptors in vitro, and for labs running metabolic or obesity-related studies, it's pretty much the standdard reference now. We typically stock it as a white to off-white powder, roughly 99% purity by HPLC — better than reagent grade for this type of work, though you'll want to confirm the batch COA for your specific protocol.

The molecular weight sits at about 4813.47 g/mol, and the CAS is 2023788-19-2 — specs you'll need for ordering but not something you'll think about once it's in the freezer. Storage is -20°C and protected from light, which is non-negotiable; leave it out at room temperture for a day or so and you'll degrade the peptide noticeably. We've had buyers try to reconstitute it in anything other than water, but it's actually soluble in water, so don't overcomplicate that step.

Most buyers go with the 5mg or 10mg vials depending on their dosing schedule, and we usually have both in stock — though lead time can stretch to 2-3 weeks if we're between. It's a lyophilized powder, so you'll need to reconstitute it yourself, which is pretty straightforward if you've handled peptides before. One thing we don't mention often: the powder can be slightly electrostatic, so weigh it in low-humidity environment.

Also, the molecular formula is C225H348N48O68, which is a long chain for a peptide, and that PEG modification on the lysine side chain actually helps with water solubility — not something you'd guess from the dry powder form. We've had some researchers ask about using it for long-term cell culture work, but honestly, it's better suited for acute assays or receptor binding studies given the stability window after reconstitution.

Anyway, the MOQ is typically 1 gram if you're buying bulk, but we can do smaller orders for single-vial validation (usually 10mg or 50mg). You'll get a COA with every batch, and SDS is availble on request — just confirm the shipping temperature requirement because dry ice isn't always included by default.
