Drinking piss after training

After my training I've been drinking my piss a lot to see whether it works and has a positive effect. I've been doing it for 5 months now and I seem to feel energised, most notably in my legs. I'm not sure if this is simply a placebo effect and so the feeling I have being entirely psychological. Even then this is still a big positive. Although obviously it's not the physical improvement I would like as well. What boxers did, or are doing this? I know JMM and that's where I got the idea from. Anyone know of any others? Due to the possible effect on my legs, I'm thinking maybe Pac due to how his legs have been transformed over recent time? Maybe this is what's in Ariza's shakes (obviously he would be using Pac's though, not his own to make it)?
