Hey , I have use old urine that is about 1 years old ...
What I have noticed that the oldest It get the better...
Old urine is like gold but I never drink it because it smell
Amoniac ... Please don't put it on your eyes cause it burn like hell , trust me I've tried ... When I have pain I just use old urine on the member for exemple my leg and the pain is gone completly with a question of second ... I would have experience more with it if I had more problem ... It kind of everything you need in life ... Also try to have urine who as no color , it tast like water ... This shoudnmt smell amoniac when it become old so maybe ( I sais maybe ) it could be drunk and use in the eyes ... But I don't know
Ps : I hope you will enderstand my message I don't usually speak english but french ...
