The Week contest: Young blood

This week's question: Clients of a new U.S. startup called Ambrosia can now pay $8,000 to have a liter of blood from a young person pumped into their veins, a questionable treatment that the firm claims can help fight the aging process. In seven words or fewer, please come up with a snappy advertising slogan that Ambrosia could use to woo customers.
