E2 sides can be controlled fairly easy, you are not gonna die or hurt yourself if you spend few days with higher BP or a bit bloated. If you did have those sides for prolonged time then you never controlled your E2 in the first place and is on you cycling badly and not on your body reacting bad from E2 lolyeah it is not high and im just speaking from my own experience. I had more sides on 600mg test P a week than ive head with a combination of 350mg test P and a dry compound like mast or primo.
There are individuals that react quite bad to e2 sides. High water retention, high BP, HCT/HB issues etc.
I am just telling him to be careful and include a test step with 350mg test a week. Wont hurt but help to judge individual drug response..
