I figure I update this thread with how I'm dealing with prolactin on my current cycle. Although it's with tren some of it should translate over to nandrolone.
I have since switched to using prami at 25mcg/day and currently experimenting with how I split the dosage up. Mast cuts my estrogen way to hard even at 80mg and 150mg test EOD. Mast + 200mg P5P helped quite a bit but just not enough for my liking, and I have some concerns over toxicity so I didn't want to go higher with P5P.
So I lowered mast to 60mg plus added prami and just like that the anxiety is gone, erections and sex drive are great. So far tren has been proven to be quite temperamental, but I rather not just write it off because of my inability to manage the sides. So far everything seems ok, maybe just a few more small tweaks.
Upon doing some research, no one really knows what causes "tren dick". In some, they fix estrogen and/or prolactin and everything is great, then in some raising their test dosage actually fixes it. We're all so different that when we're playing around with polypharamcy, all bets are off.
