I am almost positive, I got that information here, that you are to use it during cycle. Search won't work. I checked in anabolics 2000, it says to use during cycle with androgens. Since you a supplementing your body with androgens during cycle it won't lower your androgen levels, it will actually shift them more in the favor of muscle growth, because of lowered cortisol. I have heard that is best used pre contest or on a cutting cycle. I was going to use cytadren, but desided against it because of sides. I used arimidex instead.
