Cytadren should not be used for PCT after your AAS levles have decreased, as it suppresses not only estrogen production but your entire adrenal complex output. SO it suppresses testosterone output too, which you obviously don't want to do in PCT. It is more typically used during an AAS protocol to reduce cortisol production. Since at that time, you are taking exogenous test., the supression of test. by the Cytadren wouldn't matter.
I used it once, in a cycle, at 500 mg/d for 1 week, 750mg/d for week 2, 1000mg/d for week 3, all at 2-days-on, 2-off. I found it caused extreme fatigue for me. It was a challenge just to get my ass to the gym, altough once there, I was having awesome workouts. But the rest of the day, I was a zombie on that shit. Thre is alot of debate of the value of Cytadren to bb's. I'd like to hear of others' exeriences too....
yeah i used it at one tab a day. it worked well as an anti aromatase but made me feel so lethargic the rest of the day. so i am gonna try arimidex next time as i can get that quite cheap anyway. but aminoglutethimide does work
