Are you confident the prop is legit? I normally see prop changes within a week.if the prop is bunk and you taking winny and aromasin only it might cause boner issues.(I'm spectulating I have no experience with aromasin,but plenty with letro and adex) I usually avoid and ai on cycle unless needed. Often I hedge my bet with proviron or masteron for mild estro control and add a little nolva as needed. I find ai's seem to mess with my sex drive, joints and mood. I usually have some on hand incase my water retention gets out of control. Good luck I understand how frusterating this is.
