So I am taking 200mg testosterone cypionate weekly by separating that does into daily injections. I am also utilizing 1000 units of HCG a week. I have been experiencing severe headaches during sexual activity but it doesn't happen during intense training. I had a CAT scan done and there is no evidence of problems in my brain. I have been doing research and the only thing I can think of is a blood pressure or cholesterol problem although my BP usually registers as normal and I'm taking several blood pressure stabilizing supplements. I'm awaiting my lab work in the next couple of days. I don't really know what to think. I was taking Cialis and MK 677 but I got scared and discontinued them when this problem started a week ago. I spent all day yesterday in the hospital due to pain from another occurrence of this condition. Any idea on what could be causing this?
