What is Tirzepatide?

Tirzepatide is a dual GIP and GLP-1 receptor agonist — the first of its class to target both incretin hormone pathways simultaneously. By activating both GIP and GLP-1 receptors, it supports appetite control, fullness cues, and metabolic balance through complementary mechanisms.

At Calabasas Longevity, Tirzepatide is available as a pre-mixed compounded injectable — physician-prescribed and sourced from a licensed US 503A compounding pharmacy. No reconstituting required.

People who have plateaued on other GLP-1 approaches

Why pre-mixed matters. Most peptides sourced online arrive as lyophilized powder requiring reconstitution with bacteriostatic water — introducing contamination risk and dosing variability. Our compounded peptides arrive ready to inject, prepared under pharmaceutical-grade conditions by a licensed 503A pharmacy. Same compound. Dramatically higher safety standard.

Mechanisms of action

Tirzepatide's dual mechanism targets both the GLP-1 and GIP receptors. GLP-1 activation supports appetite suppression and slows gastric emptying, while GIP receptor activation has been shown to complement these effects and may improve insulin sensitivity and fat metabolism through distinct pathways.

Medication overview: Tirzepatide is a prescription medication that acts on GIP and GLP-1 receptors involved in appetite regulation and glucose metabolism.
