PeakO₂ Mushroom Blend – Adaptogenic Performance Powder

Nature figured it out a long time ago. Six organic mushrooms, grown in the USA on organic oats, stacked together in one powerhouse adaptogenic blend. Bucked Up PeakO2 Advanced Mushroom Blend is not some trendy wellness gimmick. This is serious, stackable performance fuel built for athletes who refuse to tap out.

PeakO2 is a trademarked blend of six potent adaptogenic mushroom strains, including Cordyceps (Cordyceps militaris), Reishi (Ganoderma lucidum), King Trumpet (Pleurotus eryngii), Shiitake (Lentinula edodes), Lion's Mane (Hericium erinaceus), and Turkey Tail (Trametes versicolor), all grown on USDA-certified organic oats right here in the United States.* Together, these six mushrooms may help your body adapt to the relentless demands of hard training, so you can keep pushing when everyone else is gasping.*

These mushrooms are powerful adaptogens, meaning they may help athletes adapt to both physical and mental stress.* Think of PeakO2 as your cheat code against oxidative damage. It contains elevated levels of what's known as a "master" antioxidant, L-Ergothioneine, plus beta-glucans, which may help combat oxidative stress and support faster recovery.* A reduction in oxidative damage means you may feel ready to go harder, longer.*

PeakO2 may also support oxygen uptake and oxygen utilization during exercise.* Better oxygen usage means your body may produce and sustain energy more efficiently during high-intensity efforts.* Whether you're grinding through conditioning circuits, endurance runs, or heavy compound lifts, getting more out of every breath matters.

Cordyceps leads the charge as the high-performance workhorse of the blend, known for its role in supporting oxygen delivery and endurance.* Reishi brings adaptogenic calm to the equation, helping your body manage the demands of intense training stress.* King Trumpet and Shiitake bring antioxidant firepower to help protect cellular health and support your natural recovery process.* Lion's Mane steps in for the mental side of performance, supporting focus and mental clarity so you're locked in, not just going through the motions.* Turkey Tail rounds out the stack with immune-supporting properties to keep you training consistently and bouncing back strong.*

The benefits of PeakO2 are cumulative, meaning consistent daily use is where the magic happens. Most users choose to take it as a standalone add-on, mixed right into their pre-workout, protein shake, morning coffee, or intra-workout drink. It's unflavored, stacks with everything, and keeps your formula clean with zero fillers, no artificial flavors, and no colors.

This isn't a product you take once and judge on the spot. Build it in. Stack it daily. Let the adaptogens accumulate in your system, and you'll start to notice the difference in how you feel training session after training session.*
