yeah everyday day in the gym just to fuck with him cause he gets all pumped up and on a platform preaching. he said something about taking it with water for more cut look sense something about no fat to make your skin thick. Right now i have 8 pounds of gains and held it for 2 weeks so far.
The lactose may make you hold more water giving that "thick skin" look. If trying to stay as cut as possible use water. If its not an issue and you can digest dairy than go for milk. Either way works.
