EDIT: Their site now says they are out of samples until September.
I'm always wary of both diet products and anything that incorrectly spells the word “extreme,” but in the off chance that you don't have the same strange misgivings as myself, you might enjoy this free Slim Xtreme (SX) sample pack. I'm not sure why they put (SX) after their product's name though. It's not like it's such a long name that it needs an acronym. Maybe they just like the way it sounds when you say it out loud.
