Obestatin is a new hormone just discovered that is a natural appetite suppresant. This new hormone was just published in last week's Science magazine, and already has 23,200 hits on Google heralding it as the new cure-all for obesity

(The domain obestatin.com was just registered a week ago -- it's that new)

I hereby offer these superb typos for $300 each:

obestaten.com
obesatin.com
obesetatin.com (the similarity between "obestatin" and "obese" is no coincidence. This typo may receive a lot of hits)
obistaten.com
obestatinweightloss.com
