Muscle Building Shakes: Gain 25 Pounds of Muscle with This Quick and Easy, All Natural Weight Gain Shake Recipe. Here is a quick and easy, all natural weight gain shake recipe that was a BIG part of my muscle building transformation back in December of 2008 to June of 2009. With the help of this homemade weight gainer, I packed on 25 pounds of almost pure muscle in just 6 months. In addition to eating a minimum of 4 whole food meals, you should consume at least 2 full shakes per day for an additional 2000 quality muscle building calories. You can either drink the shake as 1 serving or divide each 1100 calorie shake into 2 servings and drink them more frequently like I did…I had one between breakfast and lunch, another one between lunch and dinner, then a full serving(1100 calories) a half hour before bed and one more half serving when I woke up to take a piss in the middle of the night. Thanks for watching and Enjoy! PS don’t forget to visit my blog and grab your Free muscle reports. All you have to do is enter you’re name and email and I’ll send them right over to ya.
