I am using a mass builder product called mass tech extreme 2000. its got 60g protein per serving and 2000 calories. Tastes like cookies and cream, love this stuff. Problem is I have gained a lot of weight. I’m only 135 pounds and I put on 20 pounds using this stuff or 3 months. Also my bowel movements have literally changed from once a day to 3X per day. Is this normal?
