Product Overview
PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide derived from Melanotan II. It acts as an agonist at the melanocortin receptors MC4R and MC3R.
Its activity is central rather than vascular. In controlled laboratory settings, PT-141 is studied for its role in melanocortin-pathway signaling and is used in neuroendocrine research.
Important Note
This product is not approved for human consumption, medical or veterinary use, or diagnostic purposes. It is supplied for laboratory research only and should be handled by qualified professionals in a controlled research setting.
