Excellent Supplement!
If you want an endurance supplement here it is! I tried others such as Xendurance and all I got was G.I. issues. OptygenHP works great for me with no side effects and great results! There’s not that many reviews about it on the Internet, but maybe because people want to keep it their little secret! It does take some time to build up in your system, but when it does, you will thank yourself!

Personal opinion from a cyclist !
I’ve been using Optygen for a few months now and this is my second bottle now, i practice cycling and i do some competition here and there, while I’m fully aware of the debate around supplements like this, whether they’re backed by hard science or just clever marketing I can’t deny one thing, I feel the difference. Could it be psychological? Sure. But even if it is, that mental edge matters. In endurance sports, belief can be half the battle. And if a capsule helps me push a little harder or stay a little more focused, I’ll take it. Will i recommended to give it a try.. tottallyyy !!

1 Bottle, No Change in Performance
Been through 1 bottle no changes in any of my personal best markers; not aerobic nor anaerobic. Over 20 years racing bikes, Optygen was recommended by a friend. No changes so far. Cyclist all have power meters that can record our personal best, to date I have see no changes good or bad in power numbers or in recovery times. If this works at a cellular level, I should know by the 6 week mark so I am ordering 1 more bottle. I will post another review after that bottle. So it’s a $160 trial. 😁 If there is a change, anything positive, I will gladly change my review. Hope this helps!
