Okay, question for you smart guys. I know someone taking sublingual compounded deprenyl (from a doctor). He is taking a mg per day. He said that the deprenyl hammered his erections - as in made them much worse. His theory is that it lowered acetylcholine per this study:

Now this study is talking about neurons specifically, so I'm not sure it's really applicable to the arteries. Plus, other studies show that deprenyl improves memory and so it seems unlikely to me that ACh is negatively impacted.
I also have been taking deprenyl at the same dose, and I don't think it did much of anything either way to be honest.
Anyway, a few questions for you guys:
1. Anyone noticed a decrease in erectile strength? Increase in blood pressure, etc.?
2. Is he looking at that study correctly do you think?
3. Does anyone happen to know if low dose deprenyl does in fact lower arterial ACh? I have read many studies on the subject, but it just gives me a headache as they all seem only semi-applicable and sometimes indecipherable.
