What Charlie said!
Also, you might want to consider stacking ephedrine, caffeine, and aspirin. Again, it’s not going to help if your diet and cardio aren’t dialed in, but the stack does offer a modest thermogenic effect. As with clen , it’s very stimulating and may affect your sleep or anxiety level.
Having used clen and ECA stack in the past, as well as having dieted naturally, I’m inclined to go natural at this point (unless I decide to compete someday)
