I used the anaconda protocol. It was developed in a black ops bodybuilding lab. When you use it you can literally hear the slabs of muscle being added to your frame. 4realz though Just ON gold Standard whey and creatine. Creatine makes me look really cut up (broscience reasoning is that it's sucking sub-dermal water into my muscles). It's also pretty cheap. Only downside is i feel slightly sick to my stomach in the mornings, but that's the price you pay for gainz.
