This is a whole new thing to me. Im over 10 weeks into a cycle with Test cyp (600mg wk)and im running letro (.25 mg ed) as an AI. As of the past week i have experienced some intense anxiety to where it shot my BP up to 170/98 and made me extremely short of breathe. I have never had any side effects such as this with AAS and I am having a hard time figuring out if it is work/ environment related or something I should actually be worried about. My BP is currently 126/78. There is no one thing in common that seems to set this off, but it is really effecting sleep pattern and is a very uncomfortable feeling. Anyone ever deal with this? This very well could be all in my head... i'm kinda stumped.
