Hey, i just finished up a mass-building phase and now it's time for me to trim off the fat and sculpt, i believe in fat burners and im sure id have good results if i used one but the problem is...i have a heart condition. Im not happy with my bf%, it's not super high, but it's to high. Due to my heart problem, i cant take a fat burner loaded with stimulants. Is there a fat burner on the market that is "natural"? or am i screwed? Thanks for any feedback
