If Prolactin has become a significant concern and prevention is no longer a viable course of action, various medications can be sought after in order to directly tackle the problem. As mentioned in the introduction of this article, dopamine is the body’s natural hormone/neurotransmitter that is responsible for the suppression of Prolactin secretion. As such, various medications known as dopamine agonists have been discovered and developed in the treatment of hyperprolactinaemia. Dopamine agonists (such as Cabergoline, Bromocriptine, and Pramipexole among many others) bind to the same receptors that dopamine itself binds to, and initiates similar effects (to different degrees), resulting in an inhibition of Prolactin secretion    . Estrogen control should be sought after simultaneously as well.
Some people aromatise highly. I use Adex/day when on 500mg Test/wk as well. Confirmed by bloods, from my first cycle which showed my E2 levels right in the middle of range on that AI amount. However, as I lower bodyfat %, I do expect (hope) that my AI requirements reduce. I wonder if you've dropped a bit of bodyfat between last cycle and this one? Or also, maybe you switched AI brands? perhaps the last stuff you used was under-dosed and this current stuff is solid. Just some thoughts while you wait for bloods to come in.
