Tirzepatide 15mg is the largest single-vial format of this dual incretin peptide in the Peptide Sciences catalog, offering the lowest cost per milligram for established research protocols and extended chronic-dosing animal studies.
Tirzepatide Structure and Pharmacology
Structurally, tirzepatide is based on the native GIP sequence with modifications that confer GLP-1 receptor activity, including non-coded aminoisobutyric acid residues that resist DPP-4 degradation. A linker and C20 diacid moiety enable reversible albumin binding. These features make it a reference molecule for studying how lipidation and residue substitution influence peptide stability, receptor bias and duration of action.

Advantages of the 15mg Research Format
Choose the 15mg vial for long-duration studies, high-throughput screening or when multiple investigators share one lot. Fewer vials mean fewer reconstitution steps and more consistent data across the entire project.
Quality Control, COA and Shipping
Quality documentation matters for reproducible research. Every vial is traceable to a lot number, every lot carries an HPLC chromatogram and mass-spectrometry report, and orders are dispatched quickly from the USA in discreet, temperature-protected packaging.
