No blood panel, but anything less than that and I get a gyno flare-up. I agree that you can decrease E2 too much, but this is not likely to occur on test, with adex at anything less than 1mg. I'm aware of the small decreases in plasma GH/IGF-1 associated with adex, but i'm convinced this effect is counteracted by the anabolics and training.
My point was, I see so many threads where people advise noobs NOT to use an AI until you get symptoms, which I think is ignorant. Next thing you know, their nipples are swelled up, and their slamming mg's of adex and nolva to try and level out.
We know that nolva has a profound negative effect on IGF-1, and i notice an immediate decrease in strength and glycogen retention when using high doses of nolva on cycle. However, this has not been the case with adex
Better to start with a low dose such as .5 e3d to minimize the risk of symptoms for someone's first cycle, then to wait for them to occur.
