I've been thinking a lot about wether or not I'm ready for a cycle. How much more can i gain naturally? I'm asking hypothetically because i'm only 18 and i'm going to wait but i consider myself pretty strong and muscular for my size. How underweight am I? How much more weight should i gain 'til i'm ready? I don't weigh a lot but I'm really cut. My Stats:
Age:18
Height:5' 3''
Weight: 135 lbs
5% bodyfat
