1000 mg is fine but I would nt start taking it until PCT. it is meant to lower enzymes. Your gear raises it. It doesn't make sense to take something that will make your liver conflict with itself. The gear makes the enzymes go up, the MT makes it go down... it would make more sense to me to wait until after your done with the test or in the PCT phase where your leves are starting to come down. It would probably put the least stress on your liver.
