It's Legit

I have taken Shroom Tech for 7+ years. I decided to take a break from it just to see if I could tell a difference with my workouts and it was a drastic difference. I felt gassed out way quicker without Shroom Tech. I feel way better in my workouts with Shroom Tech

Quick boost

I was looking for something that would help with rolls. It took a few days but I noticed going from 2 5min to 4 or 5 in the first month. Now I can go a good 8 to ten taking half min break. The extra work has put me at 190 from 230 when I started.

Helps with capacity and endurance

The order came in a timely fashion. As for the product itself, I have been using it for years right before training Brazilian Jiu Jitsu. There is a notable difference in my endurance when I don’t take it before training. It gives me the capacity not only for extra rolls, but for longer sustained efforts within each roll. I especially recommend it if you’re trying to get your cardio back after some time off.

Sweat!

I’m not sure about energy as I did not see a huge difference. One thing I definitely noticed. While doing cardio, I was sweating buckets! My entire shirt and running hat was soaked. I felt a little heat, but I was not expecting how much water I would produce. If you’re looking to cut water weigh, this will definitely do it. By the way, this was not a one time occurrence. It happened every time.

LOVE.

This is the second time I've bought Shroom Tech. I love it. I take it before I go on all my hard runs and really strenuous workouts that involve sprinting and lots of HIIT. It's not so much a huge energy boost - more like sustained energy and more gas in the tank. I'd love if I could only take 2 instead of 4 pills but I think that's my only complaint.

Nailed it!

Great pre-workout supplement. Previous pre-workout supplements caused excessive jitters, so much so that my doctor recommended I stopped taking them due to it being a possible cause of irregular heartbeat. I decided to try Shroom Tech as I am a huge fan of all of the other supplements and again Onnit delivers a great product with the testing to back it. I will continue to use, thanks again for nailing it!

Beneficial

I have purchased this product a handful of times now and each and every time I take it the 4 pills (as directed by the bottle) I feel an energy come over me. I also have found how well I am able to breathe while using this product before I run a few miles. It is certainly nothing like caffeine or any energy supplement I have ever tried. Will continue to use this supplement in the future!

Shroom Tech works

Don’t like pre work outs because of the shaky, jittery feeling I usually get but Shroom tech doesn’t give me that. It’s just the right amount of energy and definitely gives you that extra push during the workout when you need it most. Definitely recommend this product!

Love the Shroom tech!

I loved this stuff!! I would take 4 capsules before my workout in the morning. I got better pumps, more energy and great focus. No itching, shakes or stomach upset from this supplement. I would take this everyday if I could afford it, which brings me to the one and only downfall if this product is its spendy!! Reccomend this for everyone, even those who are sensitive to stimulants.

Seems to work

I was looking for a natural pre-workout supplement that wouldn’t wreck my GI tract and Shroom Tech looked promising. After using it for a few weeks, I can say that it seems to work. While I don’t experience a marked increase in energy after taking it, I have noticed that my stamina has improved. I can go longer in the gym before fatigue sets in. Zero GI issues. The downside of Shroom Tech is the cost. I ordered the 84 count bottle thinking it would last me a while, but the recommended dose is four capsules. In an effort to conserve, I don’t use it for every workout. I have used other cordyceps supplements in the past that are less expensive, recommended smaller dosing and achieved similar results.
