Creatine supplement yes or no?

I am 17(almost 18) and i am 6"2 and 200 Ibs (16 st), i want to start taking a creatine supplement to bulk myself up i am already fairly muscly on my arms and shoulders and legs but i am fairly chubby around my waist so is it advisable to lose some weight first then bulk up or can i combine the two? any feedback will be very helpful thank you xx
