Tirzepatide 80mg
80 mg of tirzepatide as lyophilized powder, the ninth of ten vial fills
Tirzepatide is a peptide of 39 residues, two of them aminoisobutyric acid, with a C20 diacid on lysine 20, and it activates the GIP and GLP-1 receptors. The 80 mg vial is the ninth of ten fills and holds about 16.6 µmol as white freeze-dried powder under a rubber stopper and crimp cap. Its literature spans receptor pharmacology, structural biology and diabetes trials.

Other fills
This is the 80 mg fill. The Tirzepatide 10mg page is the main listing for this compound, with the full research summary and every fill side by side. Other fills: 5 mg, 10 mg, 15 mg, 20 mg, 30 mg, 40 mg, 50 mg, 60 mg, 100 mg.
What the research covers
Every tirzepatide fill is supplied freeze-dried. Wang’s review of solid protein pharmaceuticals gives the general reason: proteins often have to be made into solids to reach an acceptable shelf life, and lyophilization is the most common route1. The same review notes that freezing and drying are stresses in their own right and can denature proteins to differing degrees1. That is protein literature, not a tirzepatide study. The compound’s own papers are summarised on the Tirzepatide 10 mg main listing.
The Retatrutide vs Tirzepatide guide covers the literature in more depth.
How each lot is tested
Every lot is tested in PrymaLab’s own laboratory in Ashland, Kentucky before release: RP-HPLC for purity, LC-MS for identity, Karl Fischer titration for water, LAL for endotoxin and USP <71> for sterility. The results for the lot now shipping are in the certificate panel on this page, and the certificate number, key and QR code can be checked on the verify page. These are in-house results from PrymaLab Analytical, not an independent test, and the lab is not accredited to ISO 17025. The third-party testing guarantee on this page still applies: if any independent laboratory finds the wrong compound, or less than the stated purity or amount, the order is refunded and the cost of the test is reimbursed.
Frequently asked questions
What changes between the 80 mg vial and the smaller fills?
The amount of peptide, the lot number and certificate, the concentration a given volume of diluent produces, and how long one reconstituted vial stays in use. The compound, specification and tests do not change.
Is the 80 mg vial from the same lot as other fills?
No. Each fill size is made as its own lot, and the certificate panel on this page shows the lot of 80 mg vials now shipping. The lot number printed on the vial is the link between the two.
