“So far, it’s fantastic. The flavour is a welcome change—not as aggressive as drinking straight beetroot juice, and it’s super easy to use. In training, I simply feel better than usual. We’re now putting it to the test, tracking wattage, VO2 max, and other data to see the hard numbers as we go. The initial feeling, however, is incredibly promising”.

"Stamox is the ultimate edge for endurance. After a summer of training, I saw a clear difference in my runs—lower heart rate, improved VO2 max, and total control over my pacing."

Multiple World Champion & Undefeated Norwegian Champion in Winter Triathlon

"I have used Stamox consistently in both training sessions and competitions over the last half year. I feel it has given me more power in my legs, better flow, and not least, more energy when it starts to get tough. It has allowed me to push a little extra, and it has yielded results. I have achieved new personal best times in everything from the 1 English mile to the marathon – and the feeling that I still have more to give."

"Very good session tonight—I think I’ve found the missing link with Stamox. I'm seeing an effect already 2-3 hours after consumption.

Ran 1k reps in 2:58 and 400m in 68s, but the crazy part was the heart rate. It was way lower than normal, staying right in the threshold range. Averaged 166bpm on the last two reps at 3:03/km. It’s allowing me to train harder, perform longer, and recover faster."

"Frankly unbelievable. I continue my treatment and keep the miles."

"Before I started using Stamox, my morning sessions were always a struggle. I felt slow, and it felt like my circulation and energy just hadn't kicked in yet. I really struggled to get my body moving. Since I started taking it an hour before my session while I'm waking up, there’s been a massive difference. I’m performing so much better now."

Runner, working towards a sub 2:40 marathon

"I scored a nice PB last Sunday at a 10km (34:28). I got just over a week of trialing Stamox which worked very well. No GI issues like with competitor brands I've used in the past. Noticing my HR and recovery has improved slightly too so nice job! Look forward to using it more and more!"

Cyclist, Coach and Physical Education & Movement Sciences UGen Student

"Wow, I took Stamox for the first time today before my race and I was sooo good! It’s honestly a really great product. Now I’ve been using Stamox for a few weeks & I feel great. I take it alongside my training sessions & it really helps during races. It gave me a big boost during both the national time trial and road championships. Hopefully, with Stamox, I can win my first road race in the Elite 2 category"

Retired Pro Athlete

"I am super satisfied with Stamox. For harder trainings, VO2 max and FTP intervals I use 2tbs. I love the taste in the morning before training and sometimes use it at work for longer nights. I used Stamox at Dolomiti Superbike last weekend, also UCI marathon 120km 3500 asc. I took Stamox before the start of the race and seemed to work well! 2. overall amateurs, and 23. in elite"

Norwegian Biathlete

"I rely on Stamox to naturally and holistically support my body in everyday life and during intense training. Using it before every session controls my heart rate, my energy remains steady, and I recover faster with less muscle fatigue. I love the taste, the colour and how it supports my entire body. Stamox isn’t just about performance; it’s about giving my body a mindful boost to thrive under pressure. For me, it’s become essential—the “extra” that makes a difference."

Spanish Cyclist, CTEF Performance Science, Race Ready Cycling Training Coach

"Stamox has been a game changer. Tests show that Stamox can increase both my VO2 max durations and endurance durations. I personally think Stamox is the most interesting supplement to consider when trying to boost endurance performance. Not just because of its evidence, but also because of its good taste and the variety of options to take it."

Norwegian Cyclist and Personal Trainer

“When training towards big goals, it’s all about structure, consistency – and having enough energy to perform. Stamox has helped me with exactly that. I feel like my body responds better, especially on longer and tougher sessions, and I’m able to maintain intensity without that heavy-legged feeling. It gives me that little extra boost to get more out of every workout – and it’s now a regular part of my pre-session routine for both running and cycling.”

Former Team Wales and GB Boxer

"Especially in high-intensity sports like boxing, using Stamox makes breathing feel significantly easier. It also greatly enhances recovery between rounds. As I train fasted in the mornings, Stamox is perfect for supporting my recovery. Plus, it's super easy to mix with yogurt or other foods."

I've tested Stamox for a good period of time, and I'm very satisfied with the product so far. I've used it in all competitions this autumn, as well as in interval training sessions that are a bit later in the morning. I notice that Stamox helps improve performance and secure those last crucial percentages. It's also something I will definitely use even more on competition days and during intervals in the future.

"Been using Stamox Beetroot extract powder for a week now and I can't fault it. A natural endurance booster, with extensive research and development carried out in Norway. The product increases blood flow, oxygen efficiency and reduces fatigue .. for everyone training triathlon it's a big win! It's proven to increase power output in watts and VO2 max. I highly recommend using it".

5km, 10km, 21km Distance Runner

“I really like Stamox, it’s amazing. When I use it I feel relaxed, and get quicker without feeling fatigue. My pace is completely different when I use it. I have more energy to push harder at the end of my workout or race.”

I'm really excited about Stamox. It mixes much better than other powders I've tested (both in water and fruit juice). The taste is less overpowering than most other products I've tested, and it doesn't affect my stomach or intestines like the others did. The effectiveness, which is of course the most important, is simply fantastic. I can get through tough workouts more easily, and recovery is much better. My next order will include a few extra jars. Because of my enthusiasm, my coach and a teammate want to try it too, and we all hope to improve our marathon times.

"10/10 in rating if you want a product that is natural and that works! After trying Stamox, I never looked back. I always have that little extra to give when I do cardio. For hypertrophy training I can increase up to 2 to 4 reps and the body recovers much faster between sets and reps".
