Lorenzo
"So far I am very satisfied. It's too early to see permanent improvements, but I'm pushing through hard running sessions and it's starting 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.

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.

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.
I love Stamox, and use it every day. It gives the perfect boost—both physically & mentally.
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 am very satisfied with the product. My coach was also surprised that I produced the same wattage at a lower heart rate.
I'm continuing to use stamox. I've started to see the first significant benefits. I've noticed 4-5 fewer heartbeats while running
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."
Thomas Kruse
"I've been using Stamox regularly for a while now and feel it gives me more energy for both work and training. Several times I take Stamox an hour before training after work when I need a little extra boost. This week I ran 14km on Monday and 8km on Tuesday. Easy runs. Wednesday was 13km of tempo and interval running. With Stamox I've felt that the energy was there for running and recovery went faster. My partner and I both use it and are super satisfied. I'm looking forward to using Stamox for training and running throughout the summer and autumn."
Every Day Athletes
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.
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
‘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.
Runners
"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”
"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!"

"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!"
