BioTrōpicLabs AltiFuel - Extreme Sports and Altitude Supplement - Mercenaria Mercenaria (Marine Clams) Version

Does exactly what it says it’s going to do. I take this for boxing, and really is great for endurance. Allows me to breathe so much easier and have more focus throughout my workouts. Feel great during and after workout. Does not make you super jittery or anything, just makes you feel good and ready to move. Have not tried this at altitude, but I’m sure this works great as I have had the utmost success with all of the other biotropic labs oxygenating supplements. Either way, very thankful for this product. I understand it may not work the same way for everyone, but if you are an advanced athlete in need of a boost, this is for you.

I'm not a serious athlete, but I do live and play at an elevation around 5'000 feet,. Since taking AltiFuel, I have noticed during my more aggressive hikes I don't get out of breathe as easily, and I also recover faster when I do. My diet doesn't have a lot of red meat, so I likely don't get enough iron in my diet to help with the oxygenation of my blood. This product has been great to allow me to push my muscles a little harder before my lungs start getting tired.

I live in Montana at 3300’. I usually start my running or hiking adventures around 35-4500’ and go up from there to 9-11000’. Until now I have relied on Oxcia and Ultra B12 Serum to keep my oxygen levels optimized. AltiFuel Extreme Sport is a whole new level of support and defense. So far I am feeling a solid improvement below the 8K level and look forward to my first efforts above that as the ski season begins. Based on past experience with BioTropic products, I expect great results!

I used these in Nepal and had an amazing season of climbing: summiting lots of 6000m peaks and Makalu, the worlds 5th tallest peak. Felt amazing all season. I just bought more so I am ready for the next adventure.
