Makes my toughest workouts more effective!!!

"It really enhances my leg days. I also used it hiking in the Rockies. Usually, it's day 3 before my lungs start to acclimate to 11K altitudes. This time I did a tough hike on day 1 and breathing was way easier than it "should have been. " Mixed it with some IntraBlast in my water bottles. I've used IntraBlast alone on some hikes and it's great. But adding Peak O2 made it even better."

Bernard (5/5)

Excellent Product

"I recently started taking this to enhance lifting workouts and some cardio workouts throughout the week. I originally just wanted a little pump boost and figured I'd give this a try. I have always taken it with a High stim preworkout with about 6-8g of citrulline. This enhances my workout incredibly. I have noticed better breathing, better recovery, the ability to push for another rep or two, add some extra weight, and even crank out some nasty finishers. I feel more energetic during my workouts and seem to be recovering between sets more efficiently. I haven't had a long run with this but expect it to really work well."

Able to leap over tall buildings?!?!

"I mix this with cgt max and unlock for a pretty amazing pre/intra workout mix. Also, I struggle with headaches on occasion and I think this helps with that? Either way, I feel like it helps me breath deeper and I feel less winded on my sprints. The taste is pretty neutral - it is brown though. Not a big deal considering its mushrooms, but my daughter was toooootallly disgusted dad was drinking brown water."

D. R. (5/5)

Great Supplement

"This is just great to get all the benefits of different mushrooms in such an easy way. I mix a scoop with my pre-workout every morning."

Bradley O. (5/5)

Pleasant taste.

"This is easily taken. I took this with 2 other supplements in the shaker and it went down easily."

Marc L. (5/5)

Shrooms are vital

"There are so many benefits to mushrooms 🍄‍🟫 and this is a quality mix of some of their best aspects."

David R. (5/5)

If you love poop flavored water buy!

"This by far is the worst thing I ever wasted money on. From the powder smell to the texture it’s just trash. Then add water and it looks like water down poop. The flavor well not sure what poop taste like but this has to be close or worse. Buy something else."
