PT-141 (Bremelanotide) vs MOTS-c

Side-by-side comparison of key properties, dosing, and research.

Sexual Health & Libido
PT-141 (Bremelanotide)
Anti-Aging & Longevity
MOTS-c
Summary
PT-141 (Bremelanotide) is a cyclic peptide melanocortin receptor agonist that enhances sexual desire and arousal through central nervous system mechanisms. It is FDA-approved as Vyleesi for premenopausal women with hypoactive sexual desire disorder (HSDD).
MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
