My story with Cytosport's Cytogainer begins after a long hard football practice. My defensive tackle coach approached me and told me I needed to find a way to gain 20 pounds over the next few months or so. this concerned me because I've tried countless things to gain weight and nothing ever seemed to work. That's until I found Cytogainer. The first week of using it twice a day I gained 2 pounds and I noticed that my muscles looked harder and fuller. I figured my body was just adjusting to it and this wouldn't last. Well, 4 weeks later I was 7 pounds heavier than where I started from and fuller and harder than I had ever been. This stuff really works great for putting on lean muscle mass and it really fills your muscles up with nutrients. It has 54 grams of muscle building protein as well as creatine to build muscle and glutamine to help in recovery. The taste is absolutly the best I have experienced out of any protein powder and it mixes extremely well even though it's a weight gainer. I highly recommend Cytogainer to any person that is trying to put on some serious muscle mass!
