What were the results?
on some Hydroxycut hardcore one time wanting to kick start some exercise shyt I was going to be on. 
like skin rash hot. Then I started to feel sick and my heart started palpitating on some foreboding heart attack shyt
. Must have fainted to sleep and woke up sometime in the early morning feeling like shyt.

It's dangerous though, be careful.
Most fat burners just curve your appetite and maybe speed up your heart with all the caffeine, so you burn some more calories each day. They're not necessary but.. hey, not much is.
