Buy Tirzepatide Powder - Pharmaceutical Grade Weight Loss Peptide Supplier & Manufacturer

If you're buying into the GIP/GLP-1 dual agonist space for metabolic work, you've mostly seen the same batch-to-batch headaches we've dealt with for years.

The —at >99% purity by HPLC—is what we ship, and we run a full COA on every production lot, not just a spot check, so you're getting consistent mass spec and retention times each time, typically within 0.3% of teh quoted 4813.5 g/mol.

We don't do retest-for-free forever, but we do offer a straightforward retest policy within 60 days post-shipment if you store it properly (2°C-8°C before reconstitution, dessicated) and powder clumps or shifts in appearance—that's usually a sign of moisture ingress, not degradation.

Most buyers go with the 10mg vials, 10 per box, but we can do 5mg or 15mg depending on your typical dose range—just note the MOQ shifts with vial size. 40mg vials are less common but avaliable if you need high-dose reconstitution in one shot.

It's not suited for acute-dose response screening unless you're already set up with sterile diluent and calibrated balances—the reconstitution step adds variability if you're not careful. Honestly, we see more returns form folks rushing that part than from any batch inconsistency.

Each vial has its own lot number and we include the SDS and the HPLC trace as PDFs in the shipment email (check your spam if it doesn't show), so you've got the paperwork without digging through an archive.
