I've tried it and was very disappointed. Burn't plants and a horrible odor.
hahahaha you mixed it too strong... piss is good fertilizer... there is no denying that.. and just because your body doesnt need it, doesnt mean your plant cant get anything out of it, i mean, perfect example; hair, its basically crap, waste particles your body pushes out... but plants like hair in their soil, because of the nutrients available...

dont knock it till you've tried it properly...
