First Endurance OptygenHP

You may be a non-responder

I wanted to believe and I gave this a fair shot. I bought two bottles of this product ahead of my A event and took it as directed. If you are researching this product you know that you time is needed for it to build up in your system. To that end, I did two bottle and not one. The only thing that I noticed was tingling about an hour after taking the product every morning. This is the itchy scratchy uncomfortable tingling - not the good kind. I reached out to the feed and provided my story to see if perhaps they'd extend the "always happy" policy since this product requires long term use to experience results and the AI responses denied me. I guess my advice is buy one bottle at a time and see if you respond. Good luck!

Great Product

After using it consistently for 3 weeks, I feel like I am able to push harder and recover faster during workouts. No stomach issues. I definitely recommend it.

Adapto-genuine

Have used First Endurance products for 30 years and this adaptogen has played a major role in allowing me to recover and adapt to my training. First on the scene and always if the highest quality.
