Buy Tirzepatide Online - High Purity 99.9% Peptide for Research Use

The dual agonist mechanism at both GIP and GLP-1 receptors is what sets this peptide apart form single-target analogs, and for metabolic research involving insulin secretion or energy homeostasis, it’s a useful tool. We see it used in dose-response studies where the 4813.55 Da molecular weight matters for reconstitution calculations—you’ll want to account for that when preparing stock solutions. It’s not suited for acute signaling work in cell lines that lack both receptor types, so check your expression profile first.

Purity runs above 99.9% by HPLC, which is tighter than what most generic supliers guarantee, and we include the full chromatogram with each vial. The is what you’d expect, but what you won’t see is the residual solvent data—we keep that under 50 ppm, though we don’t always list it unless asked. Storage is straightforward: -20°C, light-protected, and it’ll hold for 12 months or so without degradation if you don’t freeze-thaw repeatedly.

CAS 2023788-19-2 is the identifier, but real trust point is the batch-to-batch consistency we’ve maintained over the last few hundred lots. We’ve had buyers run their own MS spectra and come back saying the isotopic pattern matches theoretical—that’s the kind of detail you don’t get from a reseller. Basically, if you need a COA with HPLC and MS data, we include it automatically, no extra request needed.

The lyophilized form is easier to handle than pre-solubilized aliquots, especially if you’re working with custom reconstitution buffers—just remember it’s hygroscopic, so open it in a dry glove box. We usually stock vials in 5mg and 10mg sizes, but the MOQ is flexible if you need bulk in bottles. One thing: the peptide is slightly sticky at low concentrations, so pre-wet your pipette tips with buffer to avoid losing matrial.

Most researchers go with the 10mg vial for multi-week studies, but if you’re doing acute injections, 5mg is plenty and reduces waste. We’ve had a few labs use this in combination with other incretin mimetics—just confirm there’s no cross-reactivity in your assay system. Anyway, teh data sheet includes all relevant specs, though we don’t always list the residual TFA content unless you ask.
