Nano-Medigel Instant Body Repair - The Start of a Real Life Medikit?

Outside the body the fluid remains fresh for a long time, but because it's made of the same amino acids the body uses it can easily be broken down inside a wound - so you can just leave it in there. No removing stitches, no after-op care. This combination of easy storage with "apply and forget" ease-of-use makes it ideal for emergency responders and battlefield use where the priority is "Stop them leaking and do it really quickly". We can't be sure if this is the same stuff as in those big boxes with red crosses on them in Doom, but if it isn't it's something damn like it.
