Hi,
I've looked into this too and my understanding is that it is not your dopamine levels that are the issue with PIED. It is your brains level of sensitiveness to dopamine. Therefore, supplementing to increase dopamine levels may not actually have any effect. Atleast not in the long term anyway. I tried l-tyrosine for a while and it definitely increased my libido for about a week and then it seemed as if my body developed some sort of tolerance and things went back to normal.
I'm currently on day 60 of no PM. I have O'd a number of times with my gf. I'm currently trying to have sex but not O to see what effects that will have. My pied is highly variable... Sometimes I'm find other times nothing seems to work. To help with the process and give me something else to focus my energy on, I'm currently cycling with 2 weeks of sulbutiamine and then 2 weeks l-tyrosine. From what I have read, sulbutiamine reduces dopamine levels and causes the brain to develop sensitivity to dopamine. I think it's like a initiating an increased flatline. Not sure how well it will work but it's something else to clutch on to.
