Absolutely true... The University of Minnesota actually found that along with tren pellets...implanting estrogen pellets in steers increased gains by 25% plus...over the same amount of time as opposed to natty cattle and 16% increase in muscle mass over tren a alone. The studies were conducted from the late 1980s thru 2002ish. I leave my e2 alone until the first signs of high e2 sides....typically in the mid 70s. 2 to 3 1mg arimidex over 2 to 3 weeks knocks me back to the 20s and i let go again. Btw Rabbit ...how you been?
