I don't much about it but the some of the info I looked at said that it is weaker than Arimidex...(See below). But if you are on cycle you muscles are in a constant Anabolic state so catablosm should not be an issue..(I think)

If desmolase has been substantially inhibited and then this is suddenly discontinued, cortisol rebound occurs. While the dosing protocol given above generally allows the user to stop "cold turkey," since desmolase inhibition is low, tapering down is nonetheless a good idea, and is in fact necessary
if, inadvisedly, doses higher than recommended were used. Arimidex (anastrozole) is a superior drug and should be used instead of Cytadren if it is available and the user can afford it.
