Progesterone Receptor
PRThe progesterone receptor. 19-nor steroids are structurally close enough to progesterone to activate it, which is why nandrolone and trenbolone produce progestogenic side effects that an aromatase inhibitor cannot touch.

Breast Tissue
Responds to both estrogen and prolactin. Once glandular tissue forms it does not go away on its own, which is why this one is worth preventing rather than treating.
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.

Erectile Function
Depends on nitric oxide signalling, which needs DHT and adequate estradiol. Compounds that suppress natural testosterone without providing strong androgenic signal are the classic cause of failure here.
Libido
Sexual desire. Needs androgen, a workable estradiol level and prolactin that is not elevated, so it fails from several directions at once.
