So you're looking at tirzepatide—it's a dual GIP and GLP-1 receptor agonist, synthetic peptide with CAS 2023788-19-2, and our company supply it as a white powder at >99% purity by HPLC, which is better than reagent grade for this type of work since you really need that tight tolerance for accurate dose-response data.

We usually have stock on the 2mg, 5mg, and 10mg vials, but confirm lead time if you need more than 50 vials or so since the 10mg format tends to run shorter—most buyers go with teh 5mg for titration studies, but it's your call depending on your batch design.


Storage is critical here: it have to be kept at -20°C, no exceptions, or you'll lose activity fast—one thing new people don't think about is that even a brief thaw-refreeze cycle can degrade purity by a few points, and that's not something you want to guess on.

Also, this stuff is strictly for research purposes only, so it's not suited for clinical or human use at all—QC testing covers a COA with HPLC data and appearance check, but we don't batch-test every vial for every possible impurity, just main ones that matter for metabolic regulation research.
