This O2 Maximum Performance product is an energy enhancer. It's a bottle where you puff in 92% oxygen. I think most people would agree more oxygen = more energy, but I wonder how much just a few puffs will do for you. The bottle servings per container is about 60 puffs at $20. Most times you'll see professional athletes use oxygen with a mask, so I really wonder how much a few puffs will help you. Plus they say it's 100% safe. Is it?
