[Warhammer 40K] Did the god emperor of mankind undergo any body modification like the space marines?

Does he have a Black Carapace or Neuroglottis?

Nope. He was 100% all natural. Well, "natural". He likely had many of the improvements that Space Marines enjoy without the need for implants. The Primarchs are the same way. Both the Emperor and his sons are mentioned as being far far larger than any human, or Space Marine, but still maintained normal proportions and appearance, as opposed to the Marines who look obviously unnatural as a result of their genetic modification and implants.
