One prohormone, five receptors, and why MC4R is the sexual-circuit hub
PT-141 makes no sense without the receptor family it targets. The melanocortin system starts from a single prohormone, POMC, and signals through five receptors (MC1R to MC5R) that each run a different job, from skin pigment to adrenal hormones to appetite.
This unit walks that system, shows where MC4R sits in the brain, and explains the knockout and cross-drug evidence that makes MC4R the receptor behind PT-141 sexual effects rather than a lucky guess.
