What is Tirzepatide?

Tirzepatide is a dual GIP/GLP-1 receptor agonist peptide drug sold as Mounjaro (type 2 diabetes) and Zepbound (weight management).

Strong trial data for glucose control and weight loss—but not comparable to collagen powder, cosmetic serums, or research peptides sold online.

Where you will see Tirzepatide

On product labels, look for the INCI name in the full ingredient list—not just front-of-pack nicknames. Concentration, formula pH, and what else is in the bottle all change how a peptide behaves on skin or hair.

How tirzepatide differs from semaglutide

Both are incretin-based weight and diabetes medicines, but tirzepatide activates both GIP and GLP-1 receptors while semaglutide is primarily GLP-1. Dosing, side effects, and insurance coverage differ—only a prescriber should choose between them.
