for the first half i tried to bulk with it. but i noticed that i couldnt gaining the weight for the amount of food i was eating. so the second bottle i cut down on the calories and fat. i give this stack a thumbs up. i look more swollen throughout the day. started at 173lbs, now i have been hovering at 180lbs. i didnt really focus on putting up more weight, but my endurance has shot through the roof. but i appreciate your guys' help with any questions i have had.
