im 21 years old, been lifting for 5 years, 6'3, 181lbs. naturally im very slim. my bodytype is muscular but I would consider myself very cut and want to gain more mass. I was thinking about just starting and completing 1 cycle of deca and test, then after the cycle is over I will bodybuild naturally for the rest of my life. I want to do this to get myself a jumpstart. pleas don't tell me about how bad steroids are, i just want to know if its possible to maintain all the gained muscle mass from one cycle only. also is I take test will I have to worry about deca dick?
