Tirzepatide is a 39–amino acid peptide that activates two incretin receptors, GIP and GLP-1, from a single molecule. That dual mechanism is why it shows up so often as a reference compound in metabolic and incretin research.
Mechanism
It binds both the GIP and GLP-1 receptors, which together act on insulin secretion and appetite signaling. Jastreboff et al. (2022) and Aronne et al. (2024) characterized its metabolic effects and how durable they were over time.

Tirzepatide is supplied as a lyophilized powder. Keep it sealed, dry, and away from light until reconstitution.
Lyophilized material is stable when frozen. Once reconstituted, keep it cold and minimise handling to preserve integrity.
Tirzepatide is a synthetic peptide compound used in laboratory research settings. Researchers studying metabolic regulation and energy homeostasis use this compound to investigate cellular signaling pathways, receptor binding affinities, and structure-activity relationships.
