^^^You do if you want to make the most out of your body. Gear from Needto's store is an excellent supplement that you should look into. It has all your essentials bro.
I was just thinking maybe i'd get ungodly results taking gear, high protein diet, and adding in the little things like BCAA's, creatine, fish oil etc. I guess gear just overpowers everything else to the point where it doesnt really matter.
