Skinny fuck here. Work hard every day manual labor, get some muscle def. but I can't gain wait. I got some good vitamins and this protein powder to help along with trying to eat more. I need to get into a lifting routine but I digress. The directions say to mix 3 cups of powder with 3 cups of milk. I got a shaker but this shit does NOT dissolve for anything. Do I need to use a blender to mix the shit or what? It does taste damn good though.
