"Stamox has been a cornerstone of my Olympic preparation."

Sophie Souwer

X2 World Champion, X3 European Champion, Olympian in Rio and Tokyo

"Stamox allows me to push harder for longer when it counts. It also tastes great, which is a nice change compared to other beetroot products. My lactate threshold jumped from 82% to 88% after using Stamox."

Daniele Di Stefano

Italian National Team, International Speed Skater & National Record Holder

"In a sport decided by hundredths of a second, Stamox gives you the physiological edge to push harder, stay lower, and finish faster."

Jente Michels

x2 European Champion, Alpecin-Premier Tech Cyclist

“The purest beetroot powder on the market. Boosted my power and VO₂ max - helping me become U23 European Champion”

Maicol Petta

Ironman Italy 2024 AG Champ, 2025 Super Long Triathlon Champ & Overall EagleXMan 2025 Champ

"My heart rate was 5-6 bpm lower at the same intensity using Stamox! I love Stamox so far and I’m super satisfied. It works fantastic and the flavour is also very good."

Daniel Egedius

Norwegian Cross Country Skier

"With Stamox I have 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."

Connor Rogers

Runner - 5km: 14:27 - 10km: 30:22

“The data doesn’t lie. I think I’ve found the missing link in my running with Stamox. 166 bpm on 3:03/km Reps”

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!”

Finn Leggeri

National & International Rower

“Overall I felt less exhausted during the tests but also recovered quicker from practice. During the 4 weeks I immediately responded to Stamox and had better sessions on the water, where I covered more distance in the same time without increasing my average heart rate. This does as well have the side effect of me staying with better technique for longer, as I tend to neglect technique when I am getting tired”.

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.”

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."

Ole-Kristian Kvanli 

2x Champion Biathlete at Norway Cup

“Stamox helped lift me to a new PB on my VO2 test. It’s become something I will definitely continue using in my training and racing.”

Ilya Podpolny

Kayaker and K9 Biathlon Champ

"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."

Mitchell Mulhern

World Champion Team Pursuit

"Achieved my all time best 30min power using Stamox! Then another PB the following week. I take Stamox 2-3 hours pre-ride."

Jack Billyard

Gravel Cyclist, Record Holder for the 351km King Alfred’s Way course.

"I re-tested my 12-minute max and saw a 2.6% increase from 448 to 460 watts, which is a serious performance jump."

Christoff Van Heerden

Head Performance Coach & National Road Champ

“When I am training threshold, I can go longer and faster with Stamox. No other supplement has worked for me, except Stamox.”

Omar Ahmed

Shettleston 10k Champion. 5km, 10km, 21km Distance Runner

“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.”

Matt Graham

Former GB & NCAA D1 Athlete, Ironman & Running Coach

"An 8-Minute PB at the 2026 London Marathon. The data is clear: improved endurance, stronger cardiovascular output, and noticeably better efficiency."

Rolf Solheimdal Johansen

Multiple World Champion in Triathlon & Undefeated Norwegian Champion in Winter Triathlon

“Since integrating Stamox, I’ve been hitting multiple new PBs. It gives me that extra gear—more explosive leg power, better flow, and the sustained energy I need to finish strong."

Ben Millar

Elite Cyclist, 30 Hill Climb Wins, 2x NES Champion

"I’ve genuinely noticed a difference in how I can sustain efforts since using Stamox. It’s become part of my routine - I love the powder. I really feel it in my riding and I’m all about the 1%"

Quilian Koch

x26 French National Champ, 3rd World & European Champ Kayaker

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.

Sebastian Ziekman

National U20 & U23 10 km Champion

"I’ve genuinely noticed a difference in how I can sustain efforts since using Stamox. I take it for my training and racing protocol for that extra edge. It supports my endurance, oxygen efficiency, and recovery."

Kallum Skhane

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."

Stig Otto Berntsen

Norwegian Cyclist

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.. Fun when my heartbeat at x2 is with this wattage at 5*8. Today I had to hold back during the interval sessions, as my legs felt so good as I take Stamox every single day".

Jordi Salvadó

Spanish cyclist and Cycling coach 

"I’ve managed to improve my power records over 10, 20, and 60 minutes in just three weeks. I recommend my athletes take it before every training session and race."

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.”

Olav S Aase

Chiropractor of Norwegian Elite Athletes at the Olympic 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”.

Hamza Saeed

Performance Coach

"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 delivers serious performance benefits while keeping my GI completely happy."

MarcoValerio Ciminelli

Italian Cyclist

"I have used beetroot powder from another supplement company before, but Stamox is significantly better. It has superior solubility, a lighter taste, and is vastly easier to digest. The other company's product contains high fiber content—which is harmful pre-workout."

Jonny

Ironman World Championships Participant 2025

"Stamox played a massive part in my performance at the Ironman World Championships. I used a double dosage on the week leading up to the race, and it was great. No issues with the increase in dosage."

Thijs Vercaemer

Marathon Runner

"I'm really excited about Stamox. It mixes much better than other powders I've tested. The taste is less overpowering, and it doesn't affect my stomach or intestines like other competitor brands did."

Ben Lynch

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!"

Gia Giulietti

World Cup 3rd Place Italian Record, 3x IRONMAN 140.6

"I absolutely love Stamox! I can clearly feel the difference: less muscle fatigue and tiredness. This has led to improvements in performance!"

Jack Daniel

Ironman

"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."

Ben Millar

Elite Cyclist, 30 Hill Climb Wins, 2x NES Champion

"I’ve genuinely noticed a difference in how I can sustain efforts since using Stamox. It’s become part of my routine - I love the powder."

Louis Keukeleire

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"

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“.

Cédric Therin

Ultra Cyclist from Corsica

"Frankly unbelievable. I continue with Stamox and keep the miles."

When I am training threshold, I can go longer and faster with Stamox. No other supplement has worked for me, except Stamox. When it’s threshold - I can simply go longer and faster.

Lasse

I just love stamox, you can literally feel it working 2 hours after taking it! Amazing product!

I’ve ordered a bunch. I’m excited to trying it out, and see if it can help improve my cycling, and getting the last edge against my peers.

Martin Kjellemar

Swedish Cyclist

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.

Adam

Before using stamox I "die out" earlier on VO2max sessions...especially on the bike. My thighs stiffen earlier. It can be many things, but I have a feeling that Stamox really helps me.

Dan Evans

x2 British Champion

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.

Gilberto Neirotti

AG Ironman Champ

"Been using Stamox for over a year now, my Stamox loading protocol before racing is 2-3 tablespoons of Stamox 3-7 days before racing. Took the win this weekend at Ironman SA. Next up is road to Kona 2026!"

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!

Jonny

Ironman World Championships Participant 2025

Been using Stamox I can't fault it. A natural endurance booster, with extensive research and development. Stamox played a massive part in the performance at Ironman Nice, World Championships 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!

Waldek

Coach, Runner, Triathlete

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.)

Philip Muller

Hybrid Athlete, Ironman

"Before my runs & bike rides I use Stamox for a VO2 max booster"

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!"

PT

Triathlete

In my practice a cyclist showed me his gain in VO2 max after i recommend him Stamox. I have a busy racing schedule this year. Using Lanzarote IM as preparation for the Norseman in August then I’m Onto Kona for the world championships which will be my 4th time there and hopefully I go a little quicker. Love the product and more importantly the benefits that it provides for my training and racing.

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!"

Connor Rogers

Runner - 5K -14:27 10K -30:29

"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."

Cooper Berry

Run Coach and Athlete

“I’m targeting 2:18 in London and need every 1 % I can get. I have been using beet powder for a while and believe it makes a real difference."

Harry Balmer

Runner & Coach

"Genuinely love using Stamox as part of my training"

Thijs

Marathon Runner

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.

"I ran my fastest season opener yesterday. I felt like I could exert more energy and performed better thanks to the altitude acclimatisation I had; I used Stamox for two days leading up to the 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!

“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.

"I am extremely satisfied with Stamox. I feel it has an effect that allows me to perform better than ever before."

"Stamox helps me optimise my marathon prep with natural beetroot nitrates. Better oxygen delivery, improved endurance, VO2 max, and more efficient efforts during key sessions. Stamox helps me delay fatigue and stay consistent week after week".

Never a bad workout with Stamox.

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!"
