I took Stacker once at work and it wasn't pleasant. Fat burner or not--it's probably rough on the heart. I think I know what crystal meth is like now.
I felt like I was on speed.

i never wanna try it, i'm scared of what it does to your heart. the only time i've ever had effects like that is when i was like 13, they thought i was getting asthma, so they gave me an inhaler. and i think i took too much, i remember my heart started racing. i went down in my basement and started doing benchpresses, and i was doing more weight then i ever could before.
that's because inhalers contain steriods
