Thank you for introducing me to this. Having done just one round, the effects are reminiscent of nitrous oxide. Very interesting indeed! As you suggest, I think I'll try this again after a bout of vigorous exercise.
Wim hof, no exercise. (but will do so later, after my normal workout routine)
As others in the thread have said, this may not be any better for my health than N2O, but it's still interesting nonetheless. Probably not something for every day.
