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.

Without Shroom-tech sport, there is no way our team could have made it through filming the first season of the series "SEE". 16 hour days often starting at 330 am meant we needed all the energy we could possibly get. Shroom-tech sport was the supplement that kept the team going strong all day while never having the crash associated with other energy supplements. Thanks Onnit!!!

Being a soldier is demanding. Obviously the physical aspects day in and day out can tear you down. Getting up each day and know you have to work out, run, train is daunting because your always physically exhausted. Since I started using Shroom Tech Sport I’ve been able to push through the fatigue and start each day off strong. Unlike pre-workout or other supplements, there isn’t a decline or crash after the initial rush of energy. The workouts are just as tough, the runs just as long but Shroom Tech is like having an extra gas tank. I can’t see myself ever switching to something else. This should be standard issue. If you need something to help you push to that next day, workout or goal then this is for you!!

very good product that i use before the gym, feels like it gives me far more energy to complete more sets and my recovery between sets feels way faster, would recommend for sure!! would you also able to consider putting a disclaimer for UK shipping that the order may incur duty and tax charges, i ordered a larger order this week and have had to pay an extra £70 on top of the fedex premium int. delivery. however though it is worth the money

Can definitely notice a difference while taking Shroom Tech Sport. Workouts seem to last as long as I want them too without getting drained before I am done. If I have a plan going into the gym I am able to stick to it and accomplish everything I want to without fear of getting tired.

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'.

Just bought my second bottle because this stuff works! I usually only take 2 per workout, and I up it to the recommended 4 for competition as to not build a tolerance too it as I have many supplements. I definitely feel the difference and have improved my times greatly on runs with it vs without it!

I am really loving these! The recommended dosage is 4 pills before a workout, but I'm a petite woman so I just take 1 for normal workouts, or 2 if I'm doing HIIT. I feel a huge difference just with that amount! There are no weird side effects, no jitters, I simply just have an extra boost of energy through my workout that feels natural. It's kind of amazing!

Works phenomenally. I do muay thai and ive been using this to help prep for an upcoming fight and i feel a hige difference. I can go harder for a longer time and im able to recover very well and re-exhaust myself again. Big difference in cardio and calisthenics. Really awesome product.

I took Shroom TECH Sport during a 100 mile trail ultramarathon. I could tell it gave me a little extra endurance and an easier time breathing when running at elevation from 30-90 minutes after taking, compared to on the natch. I used sparingly, recommended no more than 6 per 24 hour period, so when I did take them throughout the run I could tell.
