28 years old 5'8 213 13% body fat training 8 years and 6 cycles under my belt. I am running test E and Tren E. I have arimidex as well as caber. I wanted to use caber for tren sides and arimidex to control estrogen. Does blocking estrogen and prolactin/progesterone provide a leaner and harder look while on cycle? Also, does blocking estrogen and progesterone/prolactin while on cycle reduce muscle gains? I have read they are necessary for growth. Thanks.
