Every peptide, explained.

A GLP-1 receptor agonist originally developed for type 2 diabetes, now one of the most studied weight-loss compounds in medicine.

A dual GLP-1 and GIP receptor agonist. In head-to-head trials, tirzepatide outperformed semaglutide for weight loss.

A 15–amino-acid peptide derived from a protein found in gastric juice, studied for its systemic healing and anti-inflammatory effects.

A synthetic version of Thymosin Beta-4, a naturally occurring peptide with roles in cellular migration, wound healing, and tissue remodeling.

A long-acting GHRH analog that stimulates the pituitary to release growth hormone in natural pulses.

A selective growth hormone secretagogue that stimulates GH release without significant impact on cortisol or prolactin.

A coenzyme present in every cell, essential to mitochondrial energy production and DNA repair. Levels decline with age.

A naturally-occurring copper-binding tripeptide with roles in skin remodeling, wound healing, and anti-inflammatory signaling.
