High Purity Tirzepatide Powder 99% at Competitive Costco Pricing for Research

Someone running a GLP-1/GIP dual agonist study will reconstitute this in sterile buffer at roughly 1-2 mg/mL, and we’ve seen it hold up better than single-target peptides in those head-to-head glucose clamp experiments—but it’s not suited for oral dosing work, so don’t bother asking about bioavailability here.

Purity runs at ≥99% by HPLC, and the white powder form is actually easier to weigh out than the lyophilized cakes some supliers push; density sits at 1.391 g/cm³, which matters when you’re calculating reconstitution volumes for small vials.

We custom-fill from 2mg to 50mg per vial, and the 10mg size is pretty much what most buyers go with for rodent studies—just keep in mind the MOQ is 10 vials, and lead time is usually 2-4 weeks depending on batch scheduling (check stock before ordering).

Storage is 2-8°C protected from light, and if you leave it on the bench overnight, you’ll see degradation within 24 hours—we’ve had a few calls about that, so it’s worth flagging now.

COA and HPLC trace come with every batch, and the CAS is 2023788-19-2 if you need to cross-reference with your internal database; the molecular weight is 4813 g/mol, and we don’t do any private labeling below 100 vials.

Pricing lands around what you’d expect for a pharmaceutical-grade powder from a contract manufacturer—better than reagent grade for this applicaion, but confirm the shipping terms if you’re outside teh contiguous US.
