The PeptideCores Tirzepatide research pen delivers independently HPLC verified Tirzepatide — a dual GLP-1R and GIPR co-agonist — in a pre-filled pen injector format. Each pen contains 2.5mg of Tirzepatide at 99%+ purity with mass spectrometry identity confirmation and a batch-specific COA from an independent third-party laboratory. For laboratory research use only.
Tirzepatide Dual Receptor Mechanism
Tirzepatide is a 39 amino acid acylated peptide (MW 4813.47 g/mol) acting as a co-agonist at GLP-1R and GIPR. GLP-1R activation drives insulin secretion and appetite signalling. GIPR co-agonism adds incretin amplification and adipose tissue metabolic effects.
