I think using an AI and controlling estrogen is very important for many reasons other than gyno.
I know a oldschool way of looking at it is to just leave it be or use a serm if gyno is coming, becuase of gains?
what a little muscle (possibly) and some water weight?
I rather gain 10lb than 12 off cycle and keep estrogen in check and avoid a bunch of other possible issues.
plus you look like shit, being a gear user i can usually tell whos using an AI or (or sometimes bad diet and managment of sodium) you get that full fat face, Pillsbury dough boy look...
iv had 2 HUGE dudes chat me up while working as securty for nightclub downtown that just looked retarded. trying to talk gear and their "amazing hook up" etc. all the while im thinking to myself "ok yeah your big, but you look like a high BP bloated mess of shit waiting for a heart attack and cheeks like a squirrel full of nuts...
but looks aside its JUST NOT HEALTHY!
you can use gear in a less damaging way and give a crap, how? do PCT, have time off and use a fraking AI!
