How Shroom TECH Sport Works

Advanced ATP Energy

with Cordyceps Sinensis*

The idea behind Shroom TECH Sport was to create a supplement that real athletes could take safely every day — even the day of competition. We wanted clean energy, ingredients with a history of use in high-level competition, and general health benefits; we believe we have found it in our exclusive combination of cordyceps sinensis mushroom, adaptogens, antioxidants, and methyl B-12.*

Shroom TECH Sport battles exercise fatigue with a strategy unlike any other supplement on the market, providing cellular energy through the production of ATP rather than purely stimulant-based energy, and helping the body to improve oxygen utilization so you can go longer, recover faster, and set a new personal best.*

Key Ingredients
Cordyceps Sinensis
Green Tea Extract


Several thousand years ago high in the mountains of Tibet, herdsmen noticed that when their herds grazed on caterpillar fungus, they were noticeably more lively, energetic, and could stay on the move for far longer. Taking a lesson from their animal kin, they sampled the mushroom and found a similar effect. Unbeknownst to them were the mechanisms of action behind this highly prized mushroom. Containing the active ingredients adenosine and cordycepic acid, as well as a host of phytonutrients, cordyceps has been shown in some studies to increase oxygen utilization, aerobic capacity, and cellular energy.*


One of the pillars of Ayurvedic medicine, this tonifying herb that is often called “Indian Ginseng” is prized for many varied benefits. As with most adaptogens, Ashwagandha is useful in helping the body handle occasional stress by supporting a variety of bodily functions with its combination of withanolides, alkaloids, fatty acids, and amino acids.* The particular ability of Ashwagandha to help support mental acuity and reaction time, possibly due in part to cholinergic activity, also makes this herb of particular value to athletes.*

Green Tea Extract

Green tea has been associated with good health for thousands of years, but only recently has science understood exactly why. With the combination of catechins, polyphenols, and the highly potent EGCG, green tea extract has been shown to be 20 times more antioxidant-active than Vitamin C.* In addition, green tea will offer the body its well known effects on energy and metabolism.*


Rhodiola rosea herb grows in the Arctic regions of eastern Siberia. Russians have been drinking rhodiola tea for centuries as an energy booster and Russian and Chinese scientists have researched the benefits of Rhodiola root for several decades. The root has a reputation for stimulating the nervous system, enhancing work performance and decreasing fatigue.* Interestingly, in smaller doses the herb is believed to be more stimulating than in larger doses.*


B12 is one of the most popular energy-associated B vitamins, however by unlucky accident the most common lab-produced form of B12 is cyanocobalamin, not Methylcobalamin. Cyanocobalamin is created through charcoal filtering and leaves the body to shed a small amount of excess Cyanide. We are using the coenzyme form of vitamin B12, known as Methylcobalamin or Methyl B12. It's the only form of vitamin B12 which can directly participate in homocysteine metabolism.*

Fatigue Is The Enemy

"Fatigue makes cowards of us all." Whether those words were coming from the mouth of General Patton or Vince Lombardi, the truth of it remains the same. For any of us who have been in competition, we understand it all too well. For the fighter, fatigue will tell you that the jab you keep eating really isn't worth slipping. For the basketball player, fatigue will tell you to settle for the jumpshot. For the tennis player, it will tell you that you probably couldn't run down that cross-court anyway. There is no getting around the fact that fatigue is the demon every athlete must battle. Shroom TECH Sport is a new weapon to battle fatigue.*

Alright hear me out.. I would never just buy this supplement if I hadn't stumbled upon it because at face value it seems strange.. Here's my story. I've been lifting for about 5 years now and have tried probably at least 30 different pre-workouts. I've always been one to take a traditional pre-workout (caffeine, beta-alanine, creatine, malate, BCAA's, etc.) and protein shake. I have a younger sister who is die hard crossfit and she always would take these weird exotic performance and recovery supplements that cost like $50+ for less than a month's supply. I've always scoffed at it. She moved about a year ago and I stumbled upon a stash of supps in the kitchen cabinet. Most of them un-opened stuff I've never heard of. This one was of them and the first/only I've tried so far. I looked it up at first and immediately was skeptical of it. 4 capsule servings, only 7 in a bottle? For like $30! And the only ingredient I have heard of is Rhodiola (which I do take and endorse taking, but you can get it for like $8 a bottle for pure capsules of it.) So I decided to mix it in for 1-2 workouts a week for about a month on top of my normal pre-workout. I would never substitute this completely for a pre because I personally need the stims for intensity, but as an addition I did notice a HUGE difference in stamina. The first time I took it I was still going hard after like 2 hours. Normally if I start with an intense tri-superset like barbell row -> dumbell pullover -> EZ curl or something like that.. I'm drained and drop off over the next few exercises.. I had to force myself to leave because closing was coming and I felt like a million bucks when I got home for hours. Wanted to go out and conquer the world. Figured it was placebo or maybe coincidental.. but every time I took it, it continued to prove true. Disappointed to see it's on backorder because I just ran out and will definitely get more. Would recommend stacking with your normal pre-workout at least with the small bottle to try. If you train with a lot of intensity (supersets, high volume, short breaks), this will be a worthwhile investment.

Bought from onnit before. Doesn't give you a jittery high like most pre workout supplements. When using it feels like I recover from being winded much more quickly. The only downside is it is quite pricey for everyday use.

I've tried so many products from Onnit, and I trust them with their supplements. First off I've also tried ALOT of pre-workout supplements. My tolerance is quite high compared to most people. Shroom Tech sport, is a specialized Pre-Workout supplement that provides an alternative to stimulants for your body. The Cordyceps supply is different compared to your off-the-rack Pre-Workout. After taking these you'll notice a great ENDURANCE boost for your workout. You don't get the same BUZZ-STIM-HIGH like other pre-workouts, but you will feel your muscles able to do more and more and MORE. The main caffeine source is Green Tea, which is ideally more natural and mild than other products. Give it a try! This stacks great with Onnit's T+ Supplement.

My girlfriend bought me a few onnit products for Christmas. I always hear good things about the stuff on the JRE podcast and have been very curious to try out. I was kind of disappointed. I didn't feel anything off of it.

I tried this product after seeing many positive reviews and it did what it was supposed to. I had a lot of energy when I took this product not jittery but very focused. I enjoyed how I had no stomach issues when taking it definitely a nice change from other pre workouts. The one downside is the price per serving is way to high compared to other pre workouts on the market.

You can go at least an extra two hours before gassing out at the gym with this. The downside is a serving is one capsule per 50Lbs making the already steep price tag per bottle even steeper.
