Lol if you think ephedrine raises your heart rate try some pharma clen
or better yet some T3

Plenty of guys have dieted without them back in the 80s and 90s and looked much more shredded than today's guys.
If anything begin dieting without them until you hit a plateau, then choose one to use intermediately.
