Do GH Boosters Increase Prolactin?

Since these supplements stimulate the pituitary they may do more than stimulate growth hormone and prolactin inhibits testosterone. I hope someone has some knowledge about this.

All I have to offer is some of the oddities of Prolactinomas.

“Autopsy studies indicate that 6-25% of the U. S. population have small pituitary tumors. Forty percent of these pituitary tumors produce prolactin, but most are not considered clinically significant.”

That wiki entry may have some links that lead to your answer.

I believe that is the case. I know GH can cause gyno and I’m pretty sure it is prolactin induced gyno not estrogen. If it’s just a GH booster and you’re worried, selegine/deprenyl would be good.
