I bought this because I was having to drag myself to the gym. I’ve taken other N.O. boosters before, and remember that they helped me power through sets. I’ve been working a lot of overtime and I like the extra cash, but I’ve found myself making lame excuses to skip the gym lately. To top it off, there’s a baby living in my apartment building with an incredible set of lungs he likes to use at full capacity in the middle of the night. I looked in the mirror a few weeks ago and couldn’t believe the toll that long days, no sleep and neglecting my gym membership had taken on my body. That night I got on good ole Amazon and bought this. I was an athlete in college, so I’ve used plenty of supplements. I was impressed with the ingredients and max dosage of NO Pro. I pulled the trigger since they weren’t too pricey and HOLY $*!% I was not prepared. These little guys are serious, and I extended my workout a full 30 minutes the first day. You won’t find me at the gym without this now. I literally drove all the way back to my house from the gym last week (about a 20 minutes), just because I forgot my NO Pro. They help me own my workout and get the pump I need to get the job done every time. I’m 22lbs away from breaking my personal bench record from my football days and I feel like NO Pro is my secret weapon. This stuff is the real deal. Just buy it.

Good stuff.

I used to have a low energy point midday after lunch. Since I started taking this supplement, I don't hit that wall anymore. Grateful for that. No wired feeling just a natural feeling.

I didn't expect this to be as good as it was

Wow, I didn't expect this to be as good as it was! I didn't necessarily feel much of a conditioning/cardio boost as much as I noticed really good pumps and my arms looked twice as veiny. And guys, I gotta say there's a 'side-effect' that really just effects our main man part if you catch my drift. I swear when I take this stuff I'm pretty much half-mast for the rest of the day LMAO!! My girlfriend loves it when I take this stuff. I'll definitely be buying another bottle!

Top notched product!

Zhou has done it again, another high quality product. This is a high quality product to up your game during your workouts. I take this product if I’m just doing yard work all the way to when I go to the gym, just love the extra oxygen flow. I stack it with Zhou’s Horny Goat Wwed for even more of a boost. I think next I’ll order Boost Elite and stack N.O. Pro with that to see how much it boosts.

I can definitely feel the benefit!

I have PAD, peripheral artery disease, but after taking NO Pro for about a week I feel like I have much better circulation in my legs and feet. I also don’t feel the lag in energy during the day. I am very happy with the rewards for the price, and will continue taking this supplement!

Smooth ride after the burn

I’m not an exercise enthusiast but I am trying my best. My goal is to lose weight and I seem to be faint of heart when it comes to pushing through. Since I started taking these, I notice that if I just hang on a little longer through the burn it goes ‘away’. I’m not sure how to explain it. But before I would just crash (and very quickly), since taking these I noticed that sometime after my muscles start burning to just stop, if I just hang on a little longer suddenly I will feel like I CAN do more. The burn will go a way and what settles in its place is strength. Again, not sure I am explaining this well. But when the burning goes away I feel like I can just do more (making me feel stronger). I am going to continue this.

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.

Lumberjack approved.

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.

Really works, and the recovery process is much more expedient!

Honestly wasn't sure at first how something like this claims to be would work. My skepticism can also lead to a bad experience if I am negative enough, although I did my best to truly evaluate it, and I can say I indeed WILL be purchasing this again! It doesn't give me a terribly huge boost, but I can say it certainly is a noticeable difference. I am a rather heavyweight young adult and I perform some strenuous workouts often, so naturally the worst part of that is always the aches and pains of my muscles in recovery that follow the proceeding day, but this REALLY DOES help with the recovery process! The pains are much MUCH less than they used to be and I can enjoy the day without too many sore throbbing muscles. Yet again, another home run by Zhou, they never do fail to break my expectations! 😁

Excellent vasodialator

I bought this to address a problem I am having with a constricted cardiac artery while I wait for an official word from a cardiologist. I get chest pain from even a small amount of exertion. Taking the recommended dose of 4 of these allows me to walk around without chest pain. I'm really amazed at how effective it is. I buy 2 bottles at a time because 4 pills lasts about half the day. The capsules are relatively large, but could conceivably be taken apart. I have not experienced any side effects whatsoever. The increase in vascular activity helps with my overall energy as well. I take them on an empty stomach when I get up, then in the afternoon. Great stuff.
