I am 18 years old and weigh 160 lbs. I am looking to build mass and I was wondering which is the best stack to help me achieve this. I am also hoping to burn a little bit of extra fat to look more ripped and be able to see my abs. I already purchased Cyto Gainer and Animal Stak and have been looking at supps such as RPM, Drive, X-Factor, P-Slin, PowerFULL, and Anabolic Pump. Which way should I go? Any help is appreciated.
