Syringe

This item is used to give and take blood from yourself. This will be vital to giving yourself genes, since there is no other way to get your own blood.

Hold the right mouse button to draw your blood into an empty syringe. Once filled, you can shift right-click to inject the blood back into your body. You can only inject blood that is purified, so you will have to use the Blood Purifier to clean any contaminated blood.
