    Excellent product! Perfect combination of ingredients for a great workout pump with extreme vascularity…and absolutely the BEST for an astonishing erection! Believe it or not, worked better than Cialis or Viagra! Have already started recommending it to gym buddies. The GF was super impressed with the “results” in the bedroom! Like solid steel! Would highly recommend it no matter where you’re wanting to surge some extra blood to. 5 Stars all the way…and the guys at Jacked Factory are a class act!

    I am 88 years old. I had a stroke in January, 2013 and totally paralyzed on my right side. Within three days I was in physical therapy and 6 years later still work out three times a week, 45 minutes. I have recovered 80-90% of my original abilities. Before the stroke, I was scheduled for a major back operation (metal inserts). At the last minute, I opted for spinal injections around the nerve pain, lower back. I had a blood clot stroke four days later. I was in Rehab 2 days later.
    I discovered as I got better from my stroke, I no longer had any back pain. It was a good trade! But, I developed nerve caused Neuropathy which is a numbness in my both of my lower legs, ankles and feet. It’s not painful, but my ankles you like rusty hinges with the numbness. Researching supplements, which I take quite a few, I ran across N.O.XL and noted one review stated it helped his neuropathy. So, I ordered N.O.XL and have used it now about three weeks. I started with three capsule dose, about 45 minutes before my rehab session. I definitely felt a 50-75% relief of the numbness in my legs. My rehab consisted of a Nustep arm & leg machine, 50 LB pull down arm exercises, stepper, leg weight lift, one forward 50 LB and one lay backward 70 LB machine and a 50 LB left & right upper body twist Machine. All I can say is that I feel better doing the exercises. The real point is the effect on the numbness in my legs. It is almost a night/day relief feeling. The last week I have experimented taking 2 capsules late morning and one capsule that afternoon. My numbness is still reduced by the time I am in bed. I bought the test kit, and when I first tested myself my Nitric Oxide level barely showed. When I get up in the morning and test my level now, it shows a light pink, better than before. I only checked it one time a couple hours after a three capsule dose and the test was bright pink. All I’m saying is, this does have an effect on my body. I do take supplements and one mild blood pressure pill once a day. So far I have not this any side effects, but I am a little concerned about the use of this supplement this way. However I am placing an order for another bottle, because it has definitely help my condition. I thought interested parties would appreciate my experience. It has an effect on blood circulation IMHO.

    I bought this for my husband after reading about its reputed heart-boosting effects. People take nitric oxide for a variety of reasons, many of which do not have any scientific research to support them. Some of the reported benefits of nitric oxide supplements include:
    enhancing weight loss
    improving lung function in those with cystic fibrosis
    treating altitude sickness
    improving recovery after major trauma or injury
    preventing the common cold
    reducing the side effects of memory loss
    healing diabetic foot ulcers

    Most of these benefits are anecdotal, meaning that people may have reported a benefit, but there is no proof backed up by a scientific study.

    After receiving his shipment from Amazon, my husband took the recommended 3 pills per day for 2 days. On the first night, he suffered from a severe headache for most of the night. On the second day, he started suffering from severe headache again followed by severe stomach pains, diarrhea, nausea and low blood pressure. He almost passed out in the bathroom after jumping from the toilet (after diarrhea) to the sink (to throw up). His symptoms lasted for hours, even after he had taken imodium for the diarrhea and another OTC medicine for the nausea. He immediately stopped taking this garbage.

    I looked up possible side effects and found the following: For most people, taking nitric oxide supplements does not cause side effects. When side effects do occur, they are often mild and may include:

    stomach pain, bloating, or heartburn
    heart palpitations

    A study published in 2006 in JAMA found that people taking L-arginine ( an ingredient in this product) after a heart attack had a higher chance of death, experiencing a repeat heart attack, and being hospitalized than people who did not. This article does not give a comprehensive list of potential conditions where a person should not take nitric oxide supplements.

    The supplements may also interfere with medications, such as those for diabetes and high blood pressure. Anyone thinking about taking nitric oxide supplements should talk to their doctor first to ensure they will not interfere with existing conditions or any other medications they are taking.

    Wholly molly. Take three and call me in the morning. I advise anyone tonuse this on a bicep or chest workout. Most people have a tendency to have a better mind and muscle connnection. Take 3 with a Gatorade and your off to the races with a non stim preworkout pump matrix that takes your workout to the next level!

    I may not be the best person to review the product, as I’m not currently using it for its intended purpose, but I like it very much! I discovered Jacked Factory N.O. XT Nitric Oxide Supplement while doing research on natural alternatives to lower my blood pressure. Your mileage may vary, of course, but after only two days on the product, my blood pressure is down 10 points, systolic and diastolic. Once I can get my blood pressure down to a manageable level, I will restart my workout regimen, which I suppose will put me back into the category of “intended usage,” but in the meantime, I can say the product is working for me!
