I just started my 6th week of a TEST E cycle of 500 per week a few days ago, and since I've been bulking I have cut down on the cardio in order to preserve and add muscle. Right now I am definitely gaining some fat from all the extra calories (clean calories BTW) I have been eating lately. I would really love to be as lean and ripped as possible on this cycle, so I was wondering if the TEST E will keep me from losing muscle if I increase my cardio. This is my first cycle, so I don't know if the same rules of cardio apply while on the juice. I usually only do cardio 3-4 times a week in order to lose as little muscle as possible.
