bromo and caber are for prolactin. tren also stimulates the progesterone receptor in addition to increasing prolactin. Throw in some test and no AI for some increased estrogen, and you have a recipe for some nice sweater puppies.
have letro on hand as well as caber or bromo
letro will decrease expression of PgR, and eliminate estrogen
caber or bromo will nerf out prolactin, I use caber + letro with tren
