Melanocortin 4 Receptor
MC4RThe melanocortin receptor that controls appetite and central sexual arousal. It is why the melanotans suppress hunger and cause spontaneous erections, and why PT-141 works in the brain rather than in the blood vessels the way a PDE5 inhibitor does.

Hypothalamus
The control room above the pituitary. Appetite, body temperature, the reproductive axis and the GH rhythm are all set here, which is why so many peptides that produce whole-body effects act on one small area.
Limbic System
The emotional core of the brain, and androgen-receptor rich. This is where mood, threat response and aggression are set, and where steroid mental effects are thought to land.
