was wondering if there are any diet pills on the market that wont mess with your stomach. i have a pretty weak stomach, finally found a creatine that doesnt mess with me(kre alkalyn)

im not fat, im in good shape and have good size, i train hard 5 days a week, just trying to lean out a bit, get a little more defined and lose my stomach, mostly the bottom of my stomach and my sides are the problem area.

5'10, 205lbs, 27yrs old, been lifting since teens.

thanks for any help, stepped up the cardio lately and my diet is better.
