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. Stamox is a key part of the daily fuel for increased blood flow, lung capacity and recovery between sessions. With double sessions, Stamox is perfect to consume 2 tablespoons upon waking before a morning bike or run session.

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.)

"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!"

Winter Triathlon Norwegian & World Champion
Rolf used Stamox natural beetroot extract, to give him that extra edge throughout the Xtreme Triathlon of a 3.8 km Swim, 205 km Bike and 42.2 km Trail Run. With improved blood flow, better oxygen use, and delayed fatigue, he stayed strong through the long, solo segments.
I am very satisfied with the product. My coach was also surprised that I produced the same wattage at a lower heart rate.
I love Stamox, and use it every day. It gives the perfect boost—both physically & mentally.
I'm continuing to use stamox. I've started to see the first significant benefits. I've noticed 4-5 fewer heartbeats while running

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.

“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.”
Erika Jursaite
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!

2:35:08 og 14e plass i maraton debuten. Tar det med den oppladningen jeg hadde og lite grunnlag (30k i snitt i uka siste 10 uker). Håper og tror Stamox har hatt noe effekt.
Første langtur med Stamox før økten. Altså…. WOOOW!!! Dette er rent gull
Jeg løper mest lengre distanser, så har ikke hatt så mye fokus på fart. Derfor var det ekstra gøy å prøve ut Stamox for første gang i dag. Aldri løpt løp på bane før heller. Tiden er langt i fra noe å rope hurra for, men det er fort for meg, og jeg løp siste km fortest. Har masse energi og veldig bra bein etter løpet. Så dette er definitivt min nye følgesvenn til løp og hardere treninger
Jeg har astma, så for meg er det viktig å ikke gå over det punktet hvor jeg blir for tett. I dag ble det faktisk bare lettere under veis, ikke motsatt. Jeg løper langt uten problemer, men så fort jeg øker tempo litt mer enn vanlig er jeg litt i fare sonen. Tetner det til må jeg bare gi meg. Så dette var gull! Det kommer mer reklame fra meg

"One thing is for sure, and that is that with proper use, you can maintain both a higher heart rate over time with Stamox."
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.
Stig Otto Berntsen
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

I've used beetroot powder from another supplement company before. But your product is significantly better!: -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).
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.
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!”
‘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 am able to achieve much more stable and low bpm, and more watts"
l've use it today for the first time and felt really great, more power and lower heart rate, great product
"I can push more watts at a lower heart rate with Stamox"
my heart rate on the same wattage level dropped round 15 bpm - which in my opinion is crazy.

Having used Stamox consistently throughout the winter, I am now at the peak of my personal performance. I am able to contiue to increase my wattage.

“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.”
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“.

Håvard Haukenes is a 2x Olympian who has been using Stamox during his competitive years “I have been testing the product for quite some time now, and I notice good effects when I take Stamox before 30 – 40km sessions. When using Stamox, you will get an increase in oxygen utilization, blood flow, endurance, concentration and more. I myself have had very good experiences with the product and will be using it on the road to Rio 2016.”
Stian Heltne
Athlete & Coach
"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."
Lorenzo
So far I am very satisfied with the product! It’s too early to see permanent improvements, but I am pushing trough hard running training sessions and I think that it is staring to kick in! For now I am getting it only with water (also because it’s more manageable before early morning sessions). I have to try it with smoothies or yogurts when I have time for breakfast before training during weekends. As I am using the “split strategy” of Stamox timing.
As with all supplements it is difficult to say if there is an actual contribution to my runs and fitness improvement. I tend to believe that Stamox has helped me push beyond previous training limits and has contributed a lot in my recovery as well.
Hey guys!! Want to tell you that your product is insane and feel a lot of differences in my long workouts.
Robin
Love the product and feel it evolves even more when using it with some consistency. Congrats on having the three guys on the podium in Nice!!

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.

Jeg har nå brukt Stamox jevnlig en periode og synes den gir meg mer energi til jobb og trening. Flere ganger tar jeg stamox 1 time før trening etter jobb når jeg trenger litt mer boost. Denne uken så løp jeg 14km mandag og 8km tirsdag. Rolige turer. Onsdag ble det 13km tempo og interval løping. Med stamox har jeg følt at energien var der til løping og restaurering gikk fortere. Jeg og min samboer bruker det og er super fornøyd. Gleder meg til å bruke stamox på trening og løp fremover sommer og høst.

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.
Jeg selv har vært plaget med ekstremt høyt blodtrykk. Når jeg bruker stamox regelmessig så føler jeg blodtrykket er lavere. Jeg måler det jo selv imellom og ser at det har en virkning. Jeg presenterte dette for en gruppe eldre mennesker på et trenings senter som jeg har. Det var flere på senteret som mente at dette var veldig bra for dem som hadde utfordringer med pust og hjerte.
I started drinking stamox a few days ago and already my skin has cleared up a lot.

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.
Flavour & Taste
Stamox tastes significantly better... Lighter taste and consistency, and with no digestive issues! Stamox has a slightly sweet and earthy flavour.

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

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.

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.” Nikos Rigas

I have two boys that are active in cross country skiing (M19 and M18) who are in the top of their age group in Norway. It has been discussed among their cross-country friends the benefit of red beets for endurance sports. We decided to test it and I wanted to use a supplement that was proven and clean, after some investigation we selected Stamox. The benefit was promising after the first test on an interval session, and since then they have used it regularly 2-3 hour before racing. Their feedback is that they accumulate less lactate and therefore their performance improves. They have not done any measurements of lactate, so it is based on their perceived experience during the races. The latest example is that PR'ed with 1.08min and 1:30min on a local hillrace. It is not only due to Stamox since they are serious about their training, but they are certain that it helps.
Daniel Egedius

“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.”
