Wow... 600Iu and 500Iu twice a week of Human Chorionic Gonadotropin (HCG) seems like an awful lot before you get everything dialed in.
Like Chip said, Human Chorionic Gonadotropin (HCG) will knock you on your ass big time... if you are going to stay at that level I would take it at night and be prepared to feel like shit the next day.
I also agree with Chip that the Aromatase inhibitor (AI) was too high and that can really screw with you big time.
It seems we are seeing a lot of people on this forum and others who are complaining of problems from fatigue, lack of sleep, headaches etc... and it usually turns out that they have started way too high on Aromatase inhibitor (AI) or HCG.
No one has any idea how your body is goin to react to everything you are putting in it (test, HCG, AI)....it is better in my opinion to start slow, see how your body reacts check your levels in 6 weeks and go from there.
