24 amino acids

Humanin

exerts neuroprotective and cytoprotective effects in models of Alzheimer’s disease, ischemia, and metabolic stress, reducing apoptosis and improving cell survival

amino acids

Setmelanotide

is approved for chronic weight management in patients with POMC, PCSK1, LEPR deficiencies and Bardet–Biedl syndrome by reducing hunger and promoting weight loss

7 amino acids

PT-141

is FDA-approved for treatment of hypoactive sexual desire disorder in premenopausal women and is studied for sexual dysfunction in other populations, increasing sexual desire via CNS melanocortin pathways

10 amino acids

Kisspeptin

is a key regulator of the hypothalamic–pituitary–gonadal axis, controlling puberty and fertility; kisspeptin-10 also inhibits trophoblast invasion and tumor metastasis in experimental models

7 amino acids

Melanotan II

is studied as a tanning and libido-enhancing agent; increases melanin production and can reduce food intake and modulate sexual arousal in animal models and humans

4 amino acids

Epitalon

is reported to increase lifespan and reduce tumor incidence in animals, and to influence differentiation of neural and mesenchymal stem cells; is studied as an epigenetic regulatory peptide

7 amino acids

Selank

is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress

7 amino acids

Semax

is used clinically in Russia for ischemic stroke and cognitive disorders; in models it improves learning, protects dopaminergic neurons, and modulates stress responses without significant endocrine ACTH-like effects

9 amino acids

DSIP

was originally described for inducing spindle and delta sleep activity when infused into the brain of rabbits; later studies report stress-modulating and endocrine effects, though its physiological role is still debated

6 amino acids

Argireline

is a topical cosmetic peptide reported to decrease dynamic wrinkles by partially mimicking the mechanism of botulinum toxin in a non-invasive manner

8 amino acids

Snap-8

is a cosmetic peptide studied for reducing wrinkle depth by inhibiting synaptic vesicle fusion and subsequent muscle contraction in facial expression muscles
