Hey guys my name is Robert and I'm 24 years old 6'1" and 198 pounds of mostly muscle. I ran a pro hormone stack when i was younger and it was the 2nd biggest mistake of my life. (The first being not pulling out at 16 but thats for another day.) I ended up with estrogen problems. this time I am doing 300mg a week test and want to know if i should continue using an AI during pct or not?
