Or, you know, Adeptus Custodes are hand made masterpieces of genetic ingenuity. Instead of integrating foreign elements you could, theoretically, re-write pieces of gene-code to make them far greater than any Astartes without using anything like Gene-Seed or having any implanted organs.

And will someone give me a source to the Grey Knights being descended from the Emperor that is not speculation? As in, not some article on this wiki that goes "Many believe the Grey Knights..." until then I will consider anyone saying the Grey Knights are descended from the Emperors own genes to be a heretic.
