EDIT: For some reason they changed this offer to be a Facebook-only one. Here's the new link.
These free K-Pax Energy tablets check out, much to my surprise. I mean it's a legit offer, not that they actually work. I can't actually see if they provide an energy boost until I receive them, eat a few, then try to run ten marathons in a row. If I collapse after a few miles then it'll clearly be K-Pax's fault.
I wanted to make a K-PAX reference, but the only thing I remember from that movie is Kevin Spacey talking to a dog for 15 seconds.
