Synthetic 39-amino acid modified peptide with C20 fatty diacid moiety
Tirzepatide is a novel multifunctional dual incretin mimetic designed based on the native GIP peptide sequence with amino acid modifications and a C20 diacid moiety attached via a hydrophilic linker. In the SURPASS and SURMOUNT clinical trials, Tirzepatide demonstrated unprecedented reductions in glycated hemoglobin (HbA1c) and visceral adipose mass.
Acts simultaneously on both GIP and GLP-1 receptors. The GIP receptor activity promotes insulin secretion and enhances lipid buffering capacity in subcutaneous adipose tissue while dampening nausea, while the GLP-1 component suppresses appetite and slows gastric transit.
Peer-reviewed publications, clinical trials, and preclinical research investigating Tirzepatide.
Multinational phase 3 trial establishing substantial and sustained body-weight reductions of up to 20.9% with dual GIP/GLP-1 receptor co-agonist tirzepatide.
Head-to-head phase 3 trial demonstrating that the dual GIP/GLP-1 receptor co-agonist tirzepatide achieved superior glycemic control and weight reduction compared to semaglutide 1 mg.
Documented literature dosing intervals and published clinical trial protocols.
Frequency: Once weekly
“Initiated at 2.5 mg weekly for 4 weeks, then increased in 2.5 mg increments every 4 weeks up to target 5, 10, or 15 mg.”
Biological delivery routes and standardized laboratory reconstitution principles.
Administered via once-weekly subcutaneous injection.
Lyophilized peptides must be reconstituted using sterile bacteriostatic water (0.9% benzyl alcohol) and maintained strictly refrigerated between 2°C - 8°C (36°F - 46°F), shielded from light.
