Bromocriptine is a 1st generation anti-prolactin drug. The most effective treatment for normalizing prolactin levels are the anti-prolactin drugs, such as cabergoline, pramipexole, or bromocriptine. A common type of gyno reffered to as estrogen-induced gyno, but not all gyno is estrogen dependent, as prolactin has the ability to cause gyno if levels get high enough, as does progesterone. While AAS do not directly increase progesterone levels, some steroids themselves are progestins (ex. trenbolone & nandrolone), exhibiting progestagenic effects on the body. Generally, this progestagenic effect is not strong enough to cause gyno by itself, but it can certainly exacerbate the effects of estrogen, making the problem worse. In the same way, AAS are generally not able to increase prolactin high enough in order to cause gyno by itself, yet it can certainly contribute to the problem. In extreme cases, individuals using large doses of Trenbolone have been known to lactate. Although this is rare and typically only occurs in heavy users with an unfavorable response, it does occasionally happen.
Bromocriptine is an ergot derivative with D2 dopamine receptor agonist and D1 dopamine receptor antagonist activities. In medicine, it is a versatile drug with many uses thanks to its dopamine increasing effects. In bodybuilding, it's used for its ability to inhibit prolactin, and during calorie restricted dieting.
