Peptides promoted for healing tendons, muscle, gut lining and wounds. Most of what is known here comes from animals.

BPC-157, TB-500, Collagen peptides, GHK-Cu, KPV, LL-37

Peptides that make the pituitary release more growth hormone, by mimicking either GHRH or ghrelin.

CJC-1295, GHRP-6, Ipamorelin, Sermorelin, Tesamorelin

Cosmetic and medical peptides for skin ageing, pigmentation and hair.

Afamelanotide, Argireline, Collagen peptides, GHK-Cu, Melanotan II, Palmitoyl pentapeptide-4

Melanocortin peptides that act on desire and arousal in the brain.

Bremelanotide, Kisspeptin, Melanotan II

Peptides that steer the reproductive hormone cascade, used in fertility, puberty and hormone-sensitive cancers.

Gonadorelin, Kisspeptin, Leuprolide, Oxytocin

Peptides claimed to sharpen focus, ease anxiety or protect the brain. Mostly studied in Russia or in animals.

Cerebrolysin, Delta sleep-inducing peptide, Dihexa, Selank, Semax, Oxytocin

Peptides that tune immune responses or kill microbes directly.

LL-37, Thymosin alpha-1, KPV

Peptides promoted to slow ageing. Human evidence is thin across the board.
