Contains samples from bears, leeches, tigers, elephants, elephant sharks, sharks, bull sharks, ants, and anteaters. Simply hook up to a dialysis machine along with the necessary equipment and swap out your blood for genetically superior ones! 

You can add whatever blood sample you want, as far as I know. Just make sure you take the pills that allow the body to accept the new blood, or your body will reject the cross-species infusion. Remember that sampling from other animals is a great basis for experimentation!
