New 10LITERS Oxygen CAN - Pure Oxygen Can - Big Ox O2 95% Pure Oxygen - 100-200 Breaths, 1-2 Seconds Each (10CANS)

I was very ambivalent about purchasing (1) recreational O2; and (2) this particular producer. I have been making multiple trips into mountains which are at a 6000 foot altitude gain for me. My residence is just barely at sea level and I spend time at locations below sea level. Although it doesn't sound particularly difficult for most outdoors folks, I suffer blistering headaches which become more severe the longer I stay at the altitude gain. These are accompanied by severe nausea. As a migraine sufferer, I am accustomed to headache pain and nausea but altitude sickness is virtually unbearable.Someone suggested oxygen. No oxygen provider would sell me oxygen without a doctor's prescription. Oxygen generators cannot be delivered to California without a doctor's prescription.My doctor would not give me a prescription for recreational oxygen. Even if he would have; however, I could not afford the cost of oxygen. Insurance required medical justification for the prescription for which there was none as recreational oxygen is not medically justifiable.I stumbled upon this stuff on Amazon. The reviews indicated it was a gamble as far as providing relief; however, it was my last best hope. I dug around the internet and found inhalation protocols to supplement oxygen for recreational purposes. I also familiarized myself with the mechanics of the delivery system. Following protocols both before increasing altitudes and during the process, I apparently gradually acclimated to the decreased oxygen levels. During my stay, I would periodically take four or five "hits" at a time. For the last three trips, I have not suffered headaches or nausea.Each can is providing roughly 70 normal inhalations. The oxygen has a slight after taste. When I no longer experience the after taste, I open a new can. I am using roughly one can per trip with each trip lasting about 5 days. My hope is that the stuff continues to work.

Put simply, I love this product and use it almost religiously for energy, focus, stamina, and recovery. A perfect alternative to caffeine, soda, energy drinks and other poisons marketed as "pick-me-ups." I'm honestly perplexed by the bad reviews. I've been using this product for some time and have never had an issue with "empty" cans and, to be frank, I prefer this mouthpiece to boost's clunky, cumbersome face cover.

3 reasons to buy this GENIUS product..1) IT WORKS 2) IT WORKS and yeah...3) IT TOTALLY WORKS!!! It gives the brain an instant charge. It could be while working out, after a swim, playing sports or 2PM at work when your brain is no longer focused and waiting for 5PM. It's a far better option than energy shot/drink or coffee. Product is PURE, MUST HAVE & HIGHLY RECOMMENDED!!!

As an active individual who works out 5 days/week (mostly evenings), I was looking for a product to help with my endurance and recovery without adding calories. I found Big Ox during my search and decided to give it a shot. Normally, I don't write reviews after a purchase, but I am sure there are others who are looking for a product to help with the same. Get it! Easy to use and most importantly it works! I will always have a can in my gym bag.

I work really long hours and this product was amazing whenever I need a pick me up during the day of a really long shift. It helps me focus on what needs to get done. I highly recommend and will be buying again!

Amazing product. My son tried this between shifts during an ice hockey game and noticed a much faster recovery. The mouthpiece worked well and made it easy to use. Will definitely buy more.

Not very good pressure coming out of the mouth piece, and didn't last long at all. I like the Boost oxygen better

This product worked wonders for me. I used it after running in the gym. Really helped to bring me back to a relaxed state. Well worth the money.
