For example, If I take 12.5mg aromasin on Monday, the next day when I wake up I'll have morning wood, but only for that day. Come Wednesday no wood again (unless I take aromasin the day before). One would think it's because of high e2, but are there any other possible reasons? I don't even have any high e2 symptoms and have low bf, so I doubt I have high e2. But no wood unless take aromasin. Random theory: Aromasin reduces shbg, thereby increasing free testosterone. Maybe the increase in free T is the cause of having morning wood?
