I have been doing a lot of research as I dive into the world of PH's, but from everything that I've read and people I've talked to, if you can get caber it's the best option. .5-1mg every 3-4 days should really fight the prolactin effectively. Plus it's supposed to really help maintain libido, lower refractory period b/w ejaculations, and put you in a really good mood. A buddy of mine who has been using steroids for years swears by the caber and he's using trenbolone as well as pretty much every other type of steroid out there and never had a problem.
Sounds to me, though, that with the PH's that are much more mild than the steroids that unless you're really prone to prolactin sides you can do just fine using p-5-p and l-dopa together and they will help you produce more dopamine. I don't know proper dosing, but I do know you don't want to be on this for extended periods and if you use caber you don't really need either of these.
I don't have personal experience, but that's just what I've learned so I hope that helps a little bit. For estrogen related sides you could also use a mild AI or low dose of a good SERM during your cycle to fight the effects of estrogen without eliminating it. I say be on the safe side, despite the claims that these PH's won't aromatize... too much to risk to not cover all your bases.
