Melanocortin Receptor Agonist | Libido & Arousal Research | For Research Use Only
PT-141 (Bremelanotide) is a synthetic peptide analog of α-MSH (alpha-melanocyte-stimulating hormone) that acts on the melanocortin receptors MC1R and MC4R. It is widely researched for its role in enhancing sexual arousal, libido, and erectile function, particularly in models where these functions are impaired.
Unlike PDE5 inhibitors that act on the vascular system, PT-141 acts directly on the brain’s arousal centres, making it a unique compound for neuroendocrine and sexual health research.
Enhances Sexual Desire & Arousal – Studied in both male and female models
Central Nervous System Action – Stimulates MC4R receptors in the hypothalamus
Non-Hormonal & Non-Vascular Mechanism
Fast Onset in Preclinical Models – Effects observed within hours of administration
Research Applications – Sexual dysfunction, libido restoration, neuropeptide signalling
