From the first few times I used Stamox, I felt like my heart rate was 5-6 bpm lower at the same intensity! I love Stamox so far and I’m super satisfied. So far, it seems fantastic, and the flavor is also very good.

I’ve tried Stamox and I absolutely love it! I can clearly feel the difference: less muscle fatigue and a reduced sensation of tiredness… and this has inevitably led to improvements in performance! It’s a product that will accompany me throughout my preparation for the Triple Ironman World Cup!! Thank you for this top-level formulation!

Ironman Nice, World Championships - completed!! Epic experience, great race and got some solid times considering such a difficult course. Stamox played a massive part in the performance and the double dosage week leading up to the race was great! No issues with the increase in dosage, stomach felt fine! Look forward to winter training with the newly added supplement to my routine!

Your beetroot powder has been a huge help this season. My triathlon season just wrapped up (last race was the Olympic distance in Poznań, and now I’m fully focused on preparing for the Warsaw Marathon on September 28.)

Pro Triathlete

"The race today went really well and it also felt that I could keep pushing more throughout the race without getting fatigue. I don't know if it was the Stamox, but I do think it helped me! I'll keep using it this week and then use it for my next race!"

Pro Triathlete

"Training is tough right now, but I love the challenge. During these intense weeks, Stamox plays a crucial role — helping me push through hard sessions by supporting recovery and performance. Depending on the day, I adjust the dosage (2-3 spoons) to optimize energy levels — whether pre-swim, post-swim, or during those grueling rides. It’s all about tuning my body to perform at its best and recover faster. Science and strategy in action — making progress toward those big races!"

Arvid Johannesen

World Champion Cyclist

"One thing is certain: with proper use, you can maintain a higher heart rate over time with increased watts using Stamox. Yesterday I did 30 minutes at 88% of my max heart rate without it feeling too crazy or too hard. It wouldn’t have been possible without Stamox!"

Kristoffer

Norwegian Cyclist

“Stamox is really the best product on the market. You get a boost you cannot compare with something else. During today’s ride I felt like the tank never emptied, and I was riding at the front on high wattage like it was nothing“.

Dawid Szvala

Cyclist

“Thank you for this Magic Powder, I love the product! With long term use of Stamox my heart rate on the same wattage level dropped round 15 bpm - which in my opinion is crazy. Two weeks ago I did 312km with 4700m elevation, and my heart rate was not in the Red Zone too long. For me that is a big GAMECHANGER!”

Jordi Salvadó

Spanish cyclist and Cycling coach 

As a cycling coach and gravel specialist rider, Stamox has been a game changer. I’ve managed to improve my power records over 10, 20, and 60 minutes in just three weeks. As a coach at Race Ready Cycling Training, I recommend my athletes take Stamox before every training session and race due to its clear positive effects on cycling performance.

Stig Otto Berntsen

Having used Stamox consistently throughout the winter, I am now at the peak of my personal performance. I am able to continue to increase my wattage.. Gøy når man sykler ned pulsen til z2 på denne watt etter 5*8. i dag måtte jeg holde igjen på intervallene! beina sprudler nå som jeg tar stamox hver bidige dag

MarcoValerio Ciminelli

Italian cyclist

"I am able to achieve much more stable and low bpm, and more watts"

Declan

I'm getting benefit after 3 days.... So decided to get 5 more.

I have been extremely impressed by your products and the positive impact they have had on endurance athletes. Given the physiological demands of these competitions, nitrate-based supplementation is of particular interest to us, especially for its effects on oxygen efficiency, time-to-exhaustion, and the ability to sustain repeated high-intensity efforts.

Today I used Stamox for the first time, and the first effects were immediately noticeable. Lower heart rate in relation to watts. Lower perceived RPE.

l've use it today for the first time and felt really great, more power and lower heart rate, great product

Jordi

Stamox has been a game changer. 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.

‘Since taking Stamox I have seen a notable increase in HRV. It has allowed me to increase my training hours, as the properties of Stamox detoxify the body, ensuring optimal carbohydrate uptake/glycogen partitioning, greatly helping me to avoid bonking during long rides’

"I can push more watts at a lower heart rate with Stamox"

“It is a game-changer. Because of Stamox, my heart rate zones have decreased; what used to be my Threshold Power zone is now my Tempo zone. I’m using a table spoon daily ca. 2 hours before sessions. Three days before racing I’m using two table spoons.”

my heart rate on the same wattage level dropped round 15 bpm - which in my opinion is crazy.

“Faster is one thing. But don’t forget the POWER and the way it makes you recover so much better”

Felix Deinböck

A week ago I purchased your product and used it with your recommendations for my 5K Race today, I managed to get a 30sec personal best time and during the run I felt my breathing being easier to maintain as I’m running. So I wanted to say thank you for developing such a product, I will use it for my upcoming races und maybe for a few hard trainings.

Omar Ahmed

Shettleston 10k Champion 

“Stamox is 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.”

Erika Jursaite

Ultra-marathoner

So far, I cannot get a grip of whether the effects I'm feeling are related to drinking Stamox, or overall training. What I can certainly say, that I have achieved a few runs with more comfortable lower heart rate that has never really been the case. Also, I like the flavour of Stamox. This week I'm running Oslo Maraton, so I'll also do the Stamox loading as described on the website, and hopefully will be able to come to conclusions. Again, thank you very much. It's an absolute pleasure getting in touch with you every time!

Christian Braathen

"2:35:08 and 14th place in my marathon debut. I'll take that given the preparation I had and a low base (30k average per week for the last 10 weeks). I hope and believe Stamox had some effect."

A game changer for a boost in endurance

"Can’t even imagine running and NOT use Stamox"

"First long workout with Stamox before the session. Honestly…. WOOOW!!! This is pure gold."

"I mostly run longer distances, so I haven't focused much on speed. That's why it was extra fun to try Stamox for the first time today. I've also never run a race on a track before. The time is far from anything to cheer about, but it's fast for me, and I ran the last km the fastest. I have lots of energy and my legs feel great after the race. So this is definitely my new companion for runs and harder training sessions."

"I have asthma, so for me it's important not to go past that point where I become too tight in the chest. Today, it actually just got easier along the way, not the opposite. I can run far without problems, but as soon I increase the pace a bit more than usual, I'm a bit in the danger zone. If my chest tightens up, I just have to stop. So this was gold!"

Hamza

Performance Coach

Stamox is honestly the best product I have ever tried. As someone who’s battled digestion issues forever (and tried every supplement on the market), I am super picky. Stamox gives you health and performance benefits while keeping my GI happy. Stamox has been a game changer for me I use it every day.

My skin is glowing. Since stamox I felt like I have more energy, stamina, oxygen and feel my body is so much better overall. Crazy product. I’m a guy who doesn’t believe in much and use many products. Magical indeed.

I myself have been suffering from extremely high blood pressure. When I use Stamox regularly, I feel that my blood pressure is lower. I do measure it myself occasionally and see that it has an effect. I presented this to a group of elderly people at a training center that I attend. There were several people at the center who thought this was very good for those who have challenges with breathing and heart.

I started drinking stamox a few days ago and already my skin has cleared up a lot.

Stamox has a slightly sweet and earthy flavour. And with no digestive issues!

Stamox is a supplement that I look forward to every day to take - which is not normal

MarcoValerio Ciminelli

I've used beetroot powder from another supplement company before. But your product is significantly better. It has better solubility, lighter taste and consistency. The other company's product is heavier in texture and taste and also harder to digest. In fact, they contain a higher fiber content (which is harmful pre-workout).

Emil Skjellberg

Professional Norwegian Cross Country Skier

“I have now used Stamox for a solid period and am very pleased with the product so far. I've taken it for all my races this autumn, as well as for morning interval sessions. I feel Stamox helps enhance my performance and secure those final, decisive percentages. It is definitely something I plan to use even more on race days and during hard interval workouts going forward.”

Professional Norwegian Cross Country Skier

"Stamox effects my pulse especially at low intensity, a reduction of about 5 bpm. I also experienced slightly better recovery possibly, so there may have been "hidden" effects outside of training."

Frode

"My two sons (18 and 19) are top-ranked competitive cross-country skiers in Norway. After hearing about the endurance benefits of beetroot within their skiing community, we decided to trial Stamox, selected for its proven efficacy and purity. The initial results during an interval session were promising. Now, they use it as a regular pre-race supplement, taking it 2-3 hours before competition. Subjectively, they report a clear sensation of reduced lactate accumulation, leading to improved race performance. While this is based on their perception rather than formal testing, the results are tangible. In a recent local hill race, for instance, they both achieved significant personal bests, improving by 1:08 and 1:30 minutes. Their serious training regimen is the primary driver of their success, but they are confident that Stamox provides a measurable performance benefit."

Christian Cusini

Italian XC Skier

"If you are looking after the edge to make you perform better, then Stamox is it".

Daniel Egedius

Norwegian Cross Country Skier

“I recently tested Stamox during a standard workout on the roller ski treadmill, and a 3000m run. I have to say I’m very positively surprised— I had both a lower average heart rate and lower lactate levels at a higher speed than I’ve ever achieved before. In the 3000m, I set a new personal best by 20 seconds! Clocking in at 9:01, I’m super pleased with Stamox.”

Whether it’s training or competition, Stamox gives me the natural edge I need to go further, faster, stronger.

Quilian Koch

26x National Champ

It's been a relentless and rewarding season! Stamox makes me able to recover between races, resist and extend the maximum effort at the end of the stroke, increased power on the middle of the race and increase VO2max and aerobic capacity. Stamox has been a key part of my fuel, helping to sharpen my focus and maintain cognitive control when the distance and fatigue set in.

Lars Rørbakken

Strongman and Arm Wrestler

“I’ve been using Stamox for over 10 years and use it on a daily basis. When I compete I get tested regularly for doping, and can trust Stamox 100% on its quality standards.”

Roger Pedersen

Bodybuilder

"10/10 in rating if you want a product that is natural and that works! After trying Stamox 10 yeas ago, I never looked back. I always have that little extra to give when I do cardio & I can increase by reps and recovery quicker between sets"

Dette stamox greiene er så sinnsykt fantastisk!! Herregud så sterk jeg er blitt!!! og helt rått å bruke på trening! Wow, bare å gi jernet nå

Shannon Troup

"Absolutely class I do feel the benefits major. And the taste is great. So much better then the beetroot shots you can get."

Nikos Rigas 

Hyrox Athlete

Performance is not achieved through random preparation. Stamox is what supports me at the most critical point: VO2max. It’s not just a supplement, it’s an oxygenation tool that makes the difference in endurance.”

Olav S Asee

Chiropractor of Norwegian Elite Athletes at the Olympic and World Championship level

As a chiropractor for both athletes and other people, I have since 2014 recommended Stamox to many of my patients. Stamox speeds up the healing of traumas in muscles, joints and tendons. Also, many of my patients continue to use Stamox because it boosts their endurance capacity and wellbeing.
