Peptide classes

Peptides that mimic incretin hormones to influence insulin secretion, gastric emptying, and appetite. This class includes the approved metabolic drugs and newer multi-receptor agonists.

6 compounds

Peptides that prompt the pituitary to release growth hormone, via two distinct pathways: GHRH analogs and ghrelin-receptor agonists.

9 compounds

Peptides associated with thymic function and immune signalling, plus antimicrobial host-defense peptides.

5 compounds

Peptides studied largely in skin, hair, and topical contexts, including copper-binding signalling peptides and synthetic cosmetic peptides.

4 compounds

Mitochondria-derived and longevity-associated research peptides. Among the most hype-prone and least clinically validated groups.

6 compounds

Peptides studied for effects on cognition, mood, and the nervous system.

5 compounds

Peptides acting on melanocortin and reproductive-hormone pathways, including an approved agent for a specific indication.

4 compounds

Growth-hormone, IGF-axis, and related growth-factor peptides and fragments.

6 compounds

Peptides popularly discussed for healing and recovery. This group is dominated by preclinical evidence and high translation risk.
