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.

Excellent product and customer service

Excellent for any activity involving cardiovascular strength. I also used this with a bout of upper respiratory infection, which I have one in the fall and one in the winter, every year. When in good health I would take two capsules daily. After the infection, I would take two in the morning and two before bed. It greatly reduced the severity of the infection and I recovered faster.

Really amazing

I have taken shroom tech for years. It started for my love of Alpha Brain and my outright disdain for every pre-workout I have ever had. They always made me too jittery and feel bloated. Shroom TECH was a different beast. I didn't know what to expect. I was waiting for the jitters. I was waiting for that instant rush. But it never came. What I did feel was one of the best workouts I have ever had. I never felt it come on. It wasn't until I was pushing a personal best time in my 4 mile run that I realized what I felt. The perfect boost for an entire workout. The energy I felt was natural. And the best part was that it motivated me more. To push myself a little harder. I felt like I could still focus without the normal shakin and jitters. There was zero crash after. This is the perfect formula for any workout.

From an Athlete - this stuff works!

If you’re an athlete into natural fitness, DO NOT SKIP OVER THIS PRODUCT W/O A TRY. I am a former D1 swimmer who now spends my time trying all different forms of exercise. From yoga to surfing, and running to lifting, I now take this supplement before each activity. I never pump up products unless they do what they advertise. I was a skeptic at first, but must admit I have seen the results. Check me out on IG @coweik21

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.

Like putting Octane Booster in an empty tank

Initial use was for an hour plus jog/run. Could feel the energy boost when starting inclines and stepping up the pace. The feeling was like I had just poured a bottle of octane booster into a low fuel tank. Moreover, I never got the jitters like I had with B12 supplements or other endurance 'boosters'.

Big Fan of ST Sport

Purchased the ShroomTech Sport a couple of times and I'm very happy with the product. Take it on my way to early morning workouts or sometimes in the afternoons for energy support and have noticed a nice difference. Finish workouts and runs with some purpose where before it was sometimes just a matter of trudging through. Also noticed how it helps my "get up and go" at work when I need it. No jitters and no sleeplessness. Will definitely be buying again and again.

Great Energy!

I’ve taken schroom tech on two different occasions now and both times have been absolutely amazing. Great pumps at the gym and all day energy!! I don’t like most preworkouts but this one actually gives long lasting effects without a crash or making you feel like a crack head when it first hits you. Can’t recommend enough!!!

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!
