I think this has a lot to do with a downregulation of Testosterone receptors (Due to high levels of testosterone while on fin) and an upregulation of DHT receptors (Due to low levels while on fin).
When you stop taking the drug, levels of hormones return somewhat to normal but their effect has changed. Test. is less effective and DHT more effective. Hence low libido and morning erections (Testosterone), and hair loss, skin problems (DHT).
I’m sure this has been discussed and that I’m missing some important info, but what do you think? Has anyone had these receptors checked?
