Youtube censorship sucks sometimes, but this guy experimenting on himself is not nearly rigorous enough to figure out what's really happening when he is taking these supplements. When a person sets out to improve themselves with drugs, test the process on themselves, and interpret and analyze those results themselves, it's a viper's pit of biases. Obviously the experimenter has a huge personal stake in the experiment (arguably the largest; his person is the experiment!) and that generally is great for motivation but bad for science.
I like playing with nootropics but I'm also relatively healthy and I can't imagine how damaging it might be for a seriously ill person who is taking advice from youtube in a desperate and futile attempt to improve their condition and survive. The ethics are pretty complex, above my pay grade for sure.
