I've been using it for less than a month, and I'm already noticing some improvement in endurance. It's excellent!

Solid daily addition to my endurance training
Been using Peak Endurance consistently as part of my Hyrox and running prep. No stimulants, so it doesn’t interfere with anything else in my routine, and I’ve noticed a real difference in how I feel on threshold sessions and longer runs. Doesn’t upset the stomach, mixes easily, and since it’s built to be taken daily rather than cycled, it’s simple to stay consistent with. Would recommend to anyone doing endurance-based training alongside strength work.
