Previous review is below the dotted line UPDATED 3-17-2025 - 7 Years Later Hello! I was 30 years old when I started taking this. And you can see my regiment below. It was fairly rigorous. The product worked. Its great. During the 7 years between my original review and today some things have changed. I have gained weight. Lost weight. Gained it back, sign up for a 50 mile ultramarathon and get back in great shape again. This supplement is the only supplement I have stuck with. They changed their label. Ingredients and results are the same. They still recommend 4 capsules per use but I still suggest only taking 2. You will not find any additional improvement with 4 capsules that you would not gain with just taking 2. These capsules DO NOT GIVE YOU ENERGY. They wont keep you up at night, they wont affect your rate of breathing. All I notice is breathing more easily, without strain or huffing and puffing. Im in control of my lungs and they do not suffer when I push myself. I have taken these capsules late in the evening with the intention of running but end up just laying in bed until I fall asleep. They have 0 effect of sleep. I need to make this clear since some reviews are really suggesting that there may be stimulants in them. You do not feel the effect of these capsules unless you are straining your body. Hoping your lungs dont give out before your legs do. These capsules keep you moving but outside of that. It might as well be a sugar pill. In fact if you take these pills without exerting yourself. You will get no benefit. They are super subtle but they do work. I have been taking this brand for 7 years and have not experienced heart palpitations, or any weird side effect. I still buy this stuff and from my experience it is 100% benign and safe. Just take 2 capsules 20 minutes before a run and you are golden. The second supplement is electrolytes. I use saltstick brand for that. Potassium, Sodium, Magnesium. Take that with a few glugs of water and muscle fatigue is alleviated. —————————————————— My routine: I run every other day 3-5 miles and one 10 mile run on most weekends. Non run days are yoga and weights for about 1-1.25 hrs. I read all glowing reviews and decided to buy a bottle of this stuff having no experience with it. I originally started taking a half dose 30m before lifting and didn’t feel a difference. I couldn’t lift more or even do more reps than normal. What I did notice is that the time I needed to rest between sets was reduced. On days I ran I would take my half dose 30m before and hop on the treadmill or trail. Moving anywhere between a 7:40 to 10:00 minute pace. I did notice I could go faster and run longer and not be completely winded by the end of it. I then bought my second bottle after 45 days or so of this experience I had been very consistent with taking my half dose of this supplement before my work outs and decided to begin taking a full dose to feel the effect. If going from 0 to 2 was underwhelming than going from 2 to 4 was even more so. I then began to convince myself that my modest increases in performance were really from me pushing myself more due to my misguided perception that im somehow enchanced by beet root. So convinced of this I continuted to take the stuff until it ran out. This happened to fall on a run day. I hop on the treadmill and start at a 9:00 minute pace at 1% incline. 12 minutes in I was huffing and puffing, so much so that I had to reduce the incline to 0. My first thought was that I didnt eat right and I must be dehydrated. I recovered my breath and 25 min in I started to feel drained. The best way to describe it is that feeling of exerting yourself in altitude. I felt like I was spending 20% more energy and effort per mile. I didnt want to continue so I stopped and thought it was just my diet and water intake that day. Doing yoga and lifting weights or doing push ups the following day, I didn’t notice much of a difference. Lets say I do 3 sets of 25 push ups with 45 seconds in between each set with N.O. Pro. Without it, I will do the first set no problem and second set I will need a full minute of recovery and by the third I may end up only being able to do 17. For me thats within my range of performance and tolerance depending on how I feel that day. Sometimes its more sometimes less. My performance remained at this level with little change. My running performance was noticeable because it was so much less than ‘normal’. There was no way I could maintain a 8:00 minute pace for any appreciable time. For a week it didn’t hit me until I logged on amazon and N.O. Pro was suggested. “Ah-ha”, yes this must be it. I bought my third bottle and it was off to the races. Again I don’t “feel it” working and I think thats the idea. You only feel it when you stop. I also recommend taking less if you can get away with it, I don’t get much more benefit from taking 4 caps versus 2. Your mileage may vary but its true for me.

Reading what others have had to say about dosages... maybe for them they're correct. I just know that I was on this for a month and felt great, had great workouts - wife loved me taking it... Then I stopped. I stopped because I wasn't sure that this was the supplement that was showing me improvements. So, I started taking other stuff - noticed that my energy fell off, workouts weren't as long. I haven't changed my diet for a year, so I KNOW it wasn't that. Ordered some more of this and immediately felt the difference. For $25 bucks, one could pay a LOT more experimenting with different supplements to find out what's "right" for you. This is what my diet misses and what helps me with stamina, workout pump, and definitely in the bedroom.

This seems to give me more energy and less fatigue during physical activity. I pop these before a workout, before doing yard work, before bed room activity (eh hem), before any kind of physical activity. I also take these whenever I need my A game at work. I pop these throughout my trip to Disneyland and it seemed to help minimize fatigue and soreness from walking on concrete for 13 hours!

I was previously using a different brand of L Arginine and found that when taking the recommended amount of that brand I experienced water retention and leg swelling with pitting edema. It got so that I had to stop taking it as it basically crippled me and kept me from running on the treadmill or even walking my dog! I thought I'd give Zhou's product a try before totally giving up on L Arginine and have discovered that my body tolerates it very well. So far I take my pre workout dose at just two capsules 30 minutes before because taking the full recommended amount of 4 got me amped up just a little too much for my comfort. Then I take the remaining two capsules of the recommended daily dose about an hour before bedtime. My treadmill performance is now back to where I was before my adverse reaction to the other brand and an added benefit with Zhou's that I never experienced with the other is ...how to say this discretely without getting censored - let's put it this way, if you are a lumberjack then you'll definitely appreciate the increased ability to chop morning wood. Great stuff, thanks, Zhou! ***Edit: I've discovered another benefit. I've taken two types of BP medication (Lisinopril and a Diuretic) for much of my adult life even though those meds only brought my BP down to "borderline hypertensive". The Diuretic caused me to have to visit the bathroom on average every two hours even at night which makes for crappy sleep. Taking N.O. Pro, my BP dropped to "borderline low" so I quit taking the diuretic. Now my BP is in the perfect range. AND I sleep all night!! I'm hooked.

I tried these a few years ago and they worked great for a long time. Eventually they didn't. Thought maybe my body just "got used to them" and quit working or the formula was changed. The company did stand by their word and sent me a free bottle when the one did not work and refunded my money when the second did not work so I do not fault the company at all. Just tried them again since if it was a body chemistry thing it should have gone away by now, but sadly it again did not work for me. Keep in mind everyone has a different reaction/or no reaction to every supplement out there so it is hit or miss on finding something that will work for you. This DID work for me for a long while, but not anymore apparently. I still recommend trying it if you never have before. Good luck!

I had waited to do my review until I had thoroughly tried out the settlement. I have used it four times now. I am an avid cyclist, although a senior one, I still am competitive. Most recently I had worked all day and needed to get a little bit of time in on my trainer, I wasn't very motivated but was reluctantly disciplined enough to ride anyway. I had taken four of these pills and given them enough time to get into my body . I had no aspirations of doing anything spectacular on the trainer as my motivation was very lacking, I ended up sitting a PR on the trainer in raising my VO2max and also my power threshold, which is tracked by my Garmin. I'm 64 yrs young and am not an elite athlete, just trying to stay fit and slow down the aging process, while enjoying life. I had an unusual amount of energy even after I finished that ride. I bought this jar and my review is unbiased. This supplement is the real deal and I'm looking forward to it helping me take my fitness to another level.

In addition to eating beets a couple times a week, I take 1 pill daily and my bp lowered 40 points! I'm 57 and bp has been consistently 120/80!! (was 140-150 )

I started taking these two weeks ago and they are working great! I take them about 30 minutes before my workout along with ZHOU's Horny Goat Weed. Gives me great energy and I get a much better pump. Not to mention my Libido has shot through the roof. I am 44 years old and I feel like I'm 26 again when I take these. Wake up every morning ready to rock wit it lol! I was skeptical initially but after careful reading of the reviews I decided to give these products a shot and I am glad that I did. I will be a repeat customer and do recommend these products to other's looking for a little boost in your workout routine and/or bedroom activity.
