Dont drink Liquor, take Hydroxy Cut, Caffiene, or coffee while on Clen. In the same day that is! Damn this Clen! 5 freaking pounds, 5 lbs is ALL I ask for. There is someone out there that has casted a spell against me to not loose any more body fat, when I find out who it is Im going to make them drink a whole bottle of this crazy stuff!
