I've been using N. O. XT for five months and wouldn't be without it. In late April of 2018, I had one foot in the grave and the other on a banana peel, as the old saying goes. It had been a hard winter with two severe, sequential bouts of flu, coupled with the ongoing drain of caring for my disabled wife for the past twenty-one years plus. At five-eleven, my weight was down from 160 lbs. to 142 lbs. Relief had finally arrived, as my beloved had moved under a separate roof for medical reasons, lessening that burden, but I was still hacking from the chest like there was no tomorrow. I had a lot of work to do to rehab my body. Somewhere in May, thankfully, I'd recovered enough to start working out again, and I desperately needed to do so. My admittedly long fingers could wrap almost completely around my skeletal upper arm. N. O. XT was my only workout-related supplement, but taking it 30 minutes prior to working out was never an option. It's an ordeal for me to get down my supplements as nine times out of ten something will get stuck halfway down and burn until a bit of food chases it out of there. I do, however, take four capsules, once per day. At first, my workouts were strictly at home. As a former pro athlete who rode broncs and bulls back in the day, I know my body pretty well, but at first I could do neither a single pushup nor a single situp. Without this product, I was convinced my comeback would have been even more problematic than it was. Most of the critical reviews seem to focus on not "feeling" a difference. To me, that's missing the point. I didn't "feel" anything, either, but knew this stuff was important. In June and July, I had a podiatrist surgically remove both big toenails, which I'd been ripping out for the previous 26 years on my own. By today, August 30, 2018, medical results and a new gym membership had combined to produce an impressive list of facts: 1. According to the doctor, my insulted toes healed up at an astounding rate. He'd warned me the healing process could take months, but at least six to eight weeks. Both toes were completely healed, looking and feeling good, five weeks post surgery. 2. During my first visit to the podiatrist's office, my BP was 145/79, which I told the nurse sounded about right when I was about to ask a total stranger to carve my tootsies up with a scalpel. But at every succeeding visit, the numbers were much lower, with the last visit showing 117/58. It didn't occur to me until later that N. O. XT got the credit for that; I couldn't remember the last time I'd seen such great numbers. 3. At the gym, where I work out three times per week, I make the circuit of 20 different weight machines. No dedicated cardio work. Happily, not every muscle group was as weak as I'd feared; the home workouts and N. O. XT had helped me hang in there at least a little bit and my situps were back to 50 per set. But the bench press machine results were depressing in the extreme. This wasn't a complete surprise, as I'd hit an ugly, puny plateau doing pushups at home and pushups are simply upside down bench presses. But it was still depressing. Until last night. I work out around midnight, which so far lets me have the entire gym to myself, which I like. No witnesses to weakness, eh? Last night was just my fourth workout at the gym. Not expecting much, I loaded up the same weight that had been stopping me at six reps on the first set. This time, I cranked out ten. Now I'm going to try another Zhou product, N. O. Pro, but will use it in addition to N. O. XT, not as a replacement. One product in the morning, one in the evening. My weight logged in this morning at 163 lbs, which is for me a healthy number. Energy is good. Pump at the gym is especially noticeable in my forearms. Upper arms no longer feel like stick figures and I can feel some meat there when I grip them. This product works for me on multiple levels. Note: I'll be turning 75 years of age in a couple of months. ... show more

Worked well first time. I was able to swim two miles, which was double my previous distances. Since I am over 70, my NO levels have declined. I recommend you try one bottle to see how your body may react. After several repeat 2 mile swims (different days) I ordered the the larger number of pills for regular use. ... show more

I've been taking Jacked Factory for a few years now. It's definitely something I will continue to take. It helped me lose 50lbs. Not only do they have amazing stuff (literally couldn't have done it without JF) they also have amazing customer service. They recently reached out asking how I like my products. I was honest. I told them I loved their products but recently my last few orders have had some capsules in each bottle that were damaged or not filled. I didn't plan on reaching out to the but since they asked me I let then know. I was in no way shape or form wanting free products but they did make it right and sent me some replacements. And for that and their amazing customer service I'll probably always be a life time customer! I added my stack and a before and after photo. ... show more

    • Helped my Neuropathy
Size: 90 Count (Pack of 1)
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.
