The results of several human clinical trials on this compound suggest that it may meaningfully and dose dependently impact several key metrics in exercise performance and physiology. A recent trial on 13 healthy, exercising adults consuming either 1.3 grams of PeakO2 or placebo, for example, demonstrated significant increases to oxygen kinetics, aerobic power and time to fatigue. In the adults receiving the 1.3g of PeakO2 for three weeks, VO2max (a measure of aerobic capacity) increased by 11% as compared to 1.8% in placebo; TTE (total time to exhaustion) increased by 8.2%; and peak power increased by 10%.
The results were similar in an additional study with 40 healthy adults, provided both low and high-dose PeakO2 for 28 days and compared with placebo. In this trial, participants receiving the mushroom extract experienced statistically significant increases to both VO2max and heart-rate economy suggesting that PeakO2’s effects are both systemic and cumulative. That is, not only does PeakO2 exert its effects on the entirety of the human cardiovascular system likely due to the multiple mechanisms of action in the mushroom blend but these effects accumulate over time.
These results suggest that PeakO2 may have beneficial effects on:
Workout duration
Time to exhaustion
Maximum power output
Peak strength
Anaerobic peak power
Oxygen utilization during exercise
Ability to uptake oxygen
Exercise capacity

I have been using this product for a few weeks and have already inreased my weights at the gym. I had felt “stuck” previously and this is just what I needed to give me some momentum forward. So far it’s been a great product.
I cannot be sure what it is in specific I am looking for when I take these items. Maybe it's better recovery, growth, pump. I think for my workouts I am looking to gain strength, gain some lean muscle mass, and feel an overall good recovery. This really depends so I am speaking from a feeling standpoint. I do FEEL good taking this product, I do not notice and jitters, weird feelings, stuff in that realm. I cannot say this makes me more agressive; which is something I would not be looking for...but I can say that I believe this thing has helped me with my apetitie. When it comes to packing on more strength, lean muscle mass, I believe my body type is like a ecto/meso type. I know I have a hard time gettig in calories, you know body building range; like 2500 plus, (so I tend not to be hungry after exercise at times). I think this thing has some serious ingredients though (meaning my stomach doesn't turn when I take them, ectera, they have care for their product). And I do love the companies beta-alanine and creatine. I feel like I have been eating more since taking this though, and tha is something I am happy about...like I feel like it's just helping me break some thangs (food/macros) down you know what I'm saying? I need that for my not just for my life, but really I think I been enjoying my full stomach a little more. I wish I had more specific data, but for now, I would buy again.
Been using this for about 2 weeks now. Definitely feel a boost in performance when doing cardio or HIIT workouts. Service is always great and quick with Tiger Fitness too!
I originally went into this purchase with EXTREME skepticism, and was prepared to return it. Not going to happen – this stuff does exactly what it claims, and I feel the difference, during my workouts. I also think it's made it *SLIGHTLY* easier to gain muscle, rather than fat, as I am currently reverse dieting. That said, this ISN'T a miracle supplement. If you don't put in the work on your end – sticking to your macros + giving your best effort at the gym – you won't see results.
This supplement is AMAZING! It have made such a difference in my prep! My performance in the gym has been stable if not BETTER the longer I take this! It also helps with maintaining muscle mass if not helping you build.
I'm on my 2nd bottle right now. I would recommend taking it for 30 days straight before you see a difference. But I HIGHLY recommend this during anyone's prep for a show!
