This seems like a really cool, convenient new product from MuscleTech - they are like individual Crystal Light packets, 5 cals per serving, features caffeine, yohimbe, green tea extract and more. This looks like a tasty new fat burner, comes in packs of 40.

From looking at it, I can't tell if its a fat burner or energy booster.

I believe it's intended to be both- it promises the "World's Most Intense Energy Rush" and "Hardcore Strength Thermogenesis" so you can "Get Shredded Fast."
