Honestly, when I'm dieting and not using any super fat burners, I like the good OTC ones simply for fat mobilization and energy/nootropic purposes. If you get a solid one with the stuff that works, they are pretty good with minimal sides especially compared to other stuff. Much higher priced but if you can afford it they aren't bad and give a nice boost. Nothing like Clen/t3 or dnp obviously. But who runs those endlessly? Lol. Brobkaid and caffeine obviously are good, but don't do much in the mood enhancement and appetite suppressant department, and has more sides 9/10 times.
Basically. they're high priced but if you know what to look for in the ingredients they aren't all useless
