I see many people advise using aromasin or armidex on cycle as a preventative measure, but I also see tons of people saying its not necessary and to only have it on hand in case of estrogen sides.
I understand the "better safe than sorry" type thinking, but im basically wondering if its overkill to run it from start. As in, maybe its too safe?
what to do?
Do i really need an AI from start or should I wait?
How much of an impact will it have on my gains if i run it from start compared to if I dont run it?
thanks
