Yesssir they do. I highly reccomend them to anybody not wanting to use gear at all or right away. I stacked Animal Pak the multi vitamin with animal M stak and I took animal nitro G pre and post workout. I felt so damn energetic and I felt like I wasnt even phased after the end of my workout. The drive I had to workout and eat was incredible.
You should go on a clean high calorie diet though because M stak has nutrition partioning agents in it which divert the calories you intake to mass building. I was stuck at about 160lbs. I did this stack and ate hardcore and worked out hardcore and now im a clean 180-185lbs (depends because some is obviously water weight as well) and I even gained a little lean bulk. Kept all my gains.
O yeh I got real strong too compared to how I was off cycle.
