Peptide Families

Peptides, grouped by how they work

Families organise peptide Signal Records by shared mechanism — a way to browse, not a claim about evidence. Within any family the strength of evidence varies widely, from approved medications to experimental compounds with no human trials.

GLP-1 / Incretin Therapies
Gut-hormone-based medications that reduce appetite and improve glycemia and body weight — the best-evidenced peptide class.
3 published recordsMaturity: Established (semaglutide, tirzepatide) to Emerging (retatrutide).
Growth Hormone Secretagogues
Peptides that raise growth hormone / IGF-1 (GHRH analogs and ghrelin agonists).
3 published recordsMaturity: Established for one narrow indication (tesamorelin / HIV lipodystrophy) to Experimental (CJC-1295, ipamorelin).
Repair Peptides
Peptides marketed for injury and tissue healing on the basis of animal data.
2 published recordsMaturity: Experimental — both are preclinical with no human trials.
Mitochondrial / Longevity Peptides
Mitochondria-derived or longevity-oriented peptides.
1 published recordMaturity: Experimental.
Cosmetic / Skin Peptides
Peptides used in skincare / cosmetic contexts.
1 published recordMaturity: Experimental (cosmetic-grade).
