Caber is generally tolerated well by most people insofar as sides go, and it is very effective at lowering prolactin. The studies that link caber to causing heart valve leakage are with excessively high dosages and not something I'd lose sleep over.
I get virtually no sides with prami, its easier to obtain in my experience, and lets me sleep through the night while on tren... as much as 10 hours. I wake up feeling fantastic and it poses no risk to kidney or liver function (not that caber does, I'm unfamiliar with its hepa/renal toxicity)... they both get the job done for prolactin control, but with the slight boost in GH production makes Prami a no brainer in my particular case. That said, if you take it and vomit through the night, don't blame me, blame your physiology.
Prami has ill-well affects on 90pc of the people I've talked to that have taken it. I myself get deathly ill on it-- even in low doses! Caber is the best for me to combat prolactin levels. If you're not having the sides and its giving you good affects, I say stay with it! Cabergoline has worked very well in medical trials and test for prolactin levels in woman statically..
