each person responds differently. I had zero issues of acne before cycle and now I have to fight it. Small price to pay but its fairly under control. If I had pizza face I just wouldnt cycle.
Expect to jump up in weight but its your call as to how much you want to gain and how fast. Most people for their first cycle just eat enough to allow themselves to grow. Your next cycle can be a cut, then a lean bulk.
Stop over thinking and keep overeating.
