World Champions & Olympians
Arvid Johannesen
Norwegian & Nordic Champion Cyclist
"Stamox has a massive impact on my aerobic efficiency. I can maintain a 380-watt threshold at just 145 bpm, compared to 153 bpm without it. That 8 bpm difference means I’m saving energy when it matters most."
Thomas Elholm
x2 Gold National Champion Rower
"Stamox’s impact on my VO2 max is undeniable. My increase from 72.1 to 76.6 in just four months is highly unlikely through training alone—the data proves Stamox works."
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."
Rolf Solheimdal Johansen
Multiple World Champion in Triathlon
"Multiple new PBs since I started Stamox. More explosive power. Sustained energy to finish strong."
Håvard Haukenes
2x Olympian
"I continued using Stamox on the road to the Olympics. I had very good experiences using Stamox as it increases oxygen, blood flow, endurance and focus"
Jente Michels
x2 European Champion, Alpecin‑Deceuninck
"The purest beetroot powder on the market. Boosted my power and VO₂ max — helped me become U23 European Champion."
Mathis Desloges
x3 Silver Medals at the 2026 Winter Olympics
"Stamox has been a cornerstone of my Olympic preparation."
Elite Champions
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!"
Yohan Zaradzki
Belgian National Marathon Champion, 2:12 Marathon · 62:31 Half · 29' 10K
"Holding 3:07/km over 42.195 km demands exceptional efficiency. My Stamox protocol: 1 tbsp on easy days, 2 tbsp before threshold blocks, 3 tbsp for long runs. It sharpens VO₂ max, threshold, and endurance."
Daniele Di Stefano
National Record Holder, Olympian, Speed Skater
"Stamox gives me the extra edge to push harder and faster."
Scott Redding
MotoGP & World Superbike Racer
"You have heard the crazy about beetroot juice. What if I told you this is the supercharged version!"
Martin Egebjerg Olesen
Danish champion in the marathon, the half marathon & the 10K
"I love Stamox for my running".
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.
Heart Rate & Efficiency
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."
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!”
MarcoValerio Ciminelli
Italian cyclist
"Resting HR dropped from 43-45 to 36-40 BPM. Higher watts, lower RPE."
Connor Rogers
Runner - 5K -14:27 10K -30:29
"166 bpm on 3:03/km reps. The data doesn't lie. I think I’ve found the missing link with Stamox. I'm seeing an effect already 2-3 hours after consumption. It’s allowing me to train harder, perform longer, and recover faster."
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."

Whether it’s training or competition, Stamox gives me the natural edge I need to go further, faster, stronger.
Vera Lagerta Fugelli von Mühleisen
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."
VO₂ Max & Oxygen Efficiency
Kev Jackson
Hyrox Pro Athlete, World Championships Qualifier
"VO₂ max from 54 to 60 in 3 months. Resting heart rate: 37 bpm. Stamox has become a daily staple in my nutrition. Lower heart rate during training. Faster recovery. I trust it 100%."
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.”
Nikos Rigas
Hyrox Athlete
"Stamox is what supports me at the most critical point: VO₂ max. It's an oxygenation tool."
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."
Philip Muller
Hybrid Athlete, Ironman
"Before my runs & bike rides I use Stamox for a VO2 max booster"
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.”
Daniel Sveningsen
Danish Mountain Biker
"I used the Stamox here in Italy, and Stamox made Italy’s high-altitude cycling a breeze—no air difference struggles! My friend felt the same. Total game-changer on the steep climbs here".
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."
Power & Wattage
Rémi Bury
RCS French Cyclist
"I tested Stamox for one month. Same LT2 workout, 4 weeks apart: +10 watts, -10 bpm over 8 minutes. The results are clear. I'm very happy with the product — easy to take and effective." .
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."
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."
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.”
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%"
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
"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. 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."
Endurance & Stamina
Omar Hassan
Danish Marathon Runner, 2:12:17 CPH Marathon — Fastest Danish Runner
"Training at high altitude in Kenya was a cornerstone of my preparation. Integrating Stamox into this phase allowed me to fully leverage the benefits for enhanced endurance and optimal oxygen efficiency. The engine held strong for a new PB and the fastest dane."
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."
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.”
Felix Deinböck
Runner
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.
Kristoffer Abrahamsen
Norwegian Cyclist
“Stamox is really the best product on the market. You get a boost you cannot compare with something else. During todays ride I felt like the tank never emptied, and I was riding at the front on high wattage like it was nothing”.
Archie Findlay
Scottish Cyclist
"First time trying Stamox tonight, smashed my 30 minute PR by 8% and took the road bike win in the process!"
Cédric Therin
Ultra Cyclist from Corsica
"Frankly unbelievable. I continue with Stamox and keep the miles."
Jack Daniel
Triathlete
"Before I started using Stamox, my morning sessions were always a struggle. I’ve noticed a massive boost in my performance with Stamox. It used to take me a while to find my rhythm, but now my body feels fluid and ready. It’s been a game-changer for avoiding that early morning caffeine crash."
Elias Knoll
Elite Athlete
“Optimizing performance and recovery is everything. Stamox gives me that natural boost to push harder and bounce back quicker. It’s how I stay at the top of my game.”
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"
Rico Quitongo
Professional Football Player
"Love Stamox's beetroot extract powder. The benefits of the powder are unbelievable. Have noticed a massive difference since we have been using Stamox and would encourage everyone to start their Stamox journey."
Stian Heltne
Athlete & Coach
" 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."
Christian Cusini
Italian XC Skier
"If you are looking after the edge to make you perform better, and win, then Stamox is it".
Recovery & Reduced Fatigue
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."
Gaia
Double Ironman Colmar - World Cup 25 3rd Italian Record. 3xIRONMAN140.6, IRONMAN World Championship Nice 24
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!
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”.
Taste & Digestion
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."
Shannon Troup
Hydrox Athlete, IMMAF MEDALIST and IFMA MEDALIST
"Absolutely class I do feel the benefits major. And the taste is great. So much better then the beetroot shots you can get."
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 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."
Matt Berry
“Absolutely stunning powder - it looks like the finest gold (red) dust and tastes amazing! Plus, it’s a huge bonus that it’s 100% plant-based”
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!"
Long-Term Use & Trust
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"
Lars Rørbakken
Strongman and Arm Wrestler
"I've used Stamox daily for over 10 years. I get tested regularly and can trust Stamox 100% on its quality standards."
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.
Health & Wellness
"The sun damage nearly all disappeared. Maybe explained by the beets creating a 'glow'."
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.
"Tastes great & the gains are UNREAL"
Stamox has a slightly sweet and earthy flavour. And with no digestive issues!
I FINALLY found something that makes it EASY to support my heart health and energy!
Stamox helps me support healthy blood pressure and boost my energy! All you have to do is mix 1 scoop in water and you're ready to go! It is so easy and quick and it tastes SO delicious. Best part of my day!!
Stamox is a supplement that I look forward to every day to take - which is not normal
I started drinking stamox a few days ago and already my skin has cleared up a lot.
