I always did 500mg sust a week with deca. I'm going to try cyp for first time. I was thinking of doing 400mg of cyp a week or should I do 500mg of cyp since I've done 500mg of sus in the past??? They are both test but different type, or because they are both test i should keep it at 500mg and not 400mg!!! Some input please....LOL Casper
