Extra Strength Nitric Oxide Booster - 3X Strength L-Arginine AKG & Citrulline Malate - Men & Women Premium Pre Workout Nitric Booster - Natural Energy & Muscle Support, Bottled in USA - 180 Capsules

Have been using this brand for years now. Price has stayed the same. Haven'y had any problems with using it.

Great product, and the company is trustworthy. I used to spend a lot more money on NO supplements; however, this is by far the best product I have found. I take it at night.

The product is working. At start it was working better and I could see the effectsafter about 20 minutes. Most relevant I got an erection oltmost like in viagra, which in time got less or my body got used with it. I planned to take them for my heart health and energy. I rated 4 because of some lost of original effect that could be to body adjusting to it or less of the product quality. I could try to increase the dose to compensate for the body adjustment but the body will adjust again and I will have to increase the dose again, which I do not want. Conclusion, a good working prodduct so far. Thank you and keep up the good work.

I have been using this product for a few weeks and I can say that it has made a noticeable difference in my workouts and recovery. I feel more energized, focused, and pumped when I take this supplement before hitting the gym. I also notice that I can lift heavier weights and do more reps without getting tired or sore. My muscles look more defined and vascular, and I have gained some lean mass as well. This product contains a powerful blend of ingredients that support nitric oxide production, which is essential for blood flow, oxygen delivery, and muscle growth. It has L-Arginine, L-Citrulline, AAKG, Beta Alanine, Niacin, and Calcium, all in optimal doses and ratios. These ingredients work synergistically to boost nitric oxide levels, enhance performance, and speed up recovery. The capsules are easy to swallow and digest, and they don’t cause any jitters or crashes. They also don’t have any artificial colors, flavors, or preservatives. The bottle has 180 capsules, which is enough for 60 servings. The price is very reasonable for the quality and quantity of the product. I highly recommend this product to anyone who wants to take their workouts to the next level and achieve their fitness goals faster. It is one of the best nitric oxide supplements I have ever tried, and I will definitely buy it again.

They’ve changed the formula without any indication. I ordered directly from my previous order but noticed it now says a serving is 4 pills (previously 2) and it no longer includes Niacin and Calcium at all, which the niacin was something I was looking for it to include.

Very good product re-order these again

Serving size is two but maybe too much for me. Just took 2 for first time. Within an hour or two- Back of head pressure headache. Keep having to roll crack my neck. Therefore I think it's too high in sulfur making aminos (the gas builds up which can make one have popping knees, toes, neck, etc from too much protein). So much pressure in my neck vertabraes that I have nerve pain down my left arm. Update: Wow, feel pretty good the next morning and slept very well. My breathing isn't as shallow and my face looks rejuvenated. I'll update again after taking for a while. Second update: Love this. I take one in morning and one in afternoon if I remember. My tight hip adductor muscle is better! I no longer limp after 20 or more minutes of walking. I'm so thrilled. I believe it was from this. I can now lose weight by walking my butt off and have less muscle fatigue from this supplement as well. These aminos are like a medicine for me.

As advertised

After i take 2 capsules daily as suggested by blood pressure drops from the range 140/150 to 125/135. I waited 3 weeks before post the review to make sure of the results. If a day i do not take the capsules , pressure rise again.

I recently purchased the SILVERONYX Extra Strength Nitric Oxide Supplement on Amazon, and I have been genuinely impressed with its performance and quality. The bottle contains 180 capsules, which offers excellent value and a long-lasting supply, making it easy to stay consistent with my supplementation. Right from the start, I appreciated the professional packaging and clear labeling, which gave me confidence that this product was carefully formulated with quality ingredients and transparent dosages. What attracted me most to this supplement is its potent blend of key nitric oxide boosters: L-Arginine, Citrulline Malate, AAKG, and Beta Alanine. These ingredients are well-known for their roles in supporting increased blood flow, improved muscle endurance, and enhanced workout performance. The fact that this product contains a 3X strength formula shows that it is designed for serious athletes and fitness enthusiasts who want to push their limits and maximize their training potential. After incorporating these capsules into my routine, I began to notice a difference fairly quickly. One of the most noticeable effects was an improvement in my workout stamina and endurance. I could train harder and for longer periods without feeling as fatigued, which allowed me to really challenge myself during weightlifting and cardio sessions. The enhanced blood flow provided by the nitric oxide boosters also seemed to contribute to better muscle pumps, making my workouts feel more productive and satisfying.
