You cannot cure TMAU 2 at home because you'll need to put the fecal sample on the small intestine itself. You can only do the colon at home which is basically useless.
To put donor sample on Small Intestine, you'll need to put tube from mouth all the way to top part of the small intestine. This needs to be done by a doctor to be safe.
Also, research shows that donor sample matters. Not all samples cured colitis because they all have different variants.
