Tirzepatide

Tirzepatide is a lab-made peptide built from 39 amino acids, designed to act on two receptors at once: the GIP receptor and the GLP-1 receptor. It’s best known in research for the incretin pathway and energy metabolism, and that dual-receptor design is what makes it stand out from single-target peptides.

It also sits on a solid research foundation, with work exploring how a single molecule can switch on both signals together (Coskun et al., 2018, Molecular Metabolism). That’s why it comes up so often in studies on dual-incretin signaling.

Research Applications

• Incretin-pathway and receptor research
• Energy-metabolism research models
• Dual GIP and GLP-1 studies
• Structure-activity peptide research

Supplied as a lyophilized powder for stability.
