I am currently on my 2nd week of Animal Stak while taking Muscle Marinade as my PWO and Green MAGnitude as my post workout creatine along with protein. I must say that Animal Stak is the first natty I have taken that lives up to its hype. I have put on visible size on my arms, chest and legs. Also I have been told that I look a bit slimmer. I do notice it in the 2 pics I have taken. 1 before and 1 at 2 weeks. I will probably run another can of Animal Stak right after this one and then decide on my next step after the 2nd can.
