i would recomend to research more before you buy or start anything bro. This is serious stuff!! Research what PCT because i'm pretty sure you dont know what that is if you dont even know what you took last time.

4.5 months training experience IMO is not enough. Train hard, eat right . cardio would defenitely help you lower that body fat. 6'1 with 204 lbs 18% BF is not good shape bro!
