This has three side effects, allows for the transport of more blood (and nutrients) and it gives you the highly sought after pump feeling while working out. The third side effect is that you get boners pretty easily while working out or just your normal morning wood. So be careful with both haha. As with most supplements they tell you to take as many pills as they feel like they can get away with telling you to so that you burn through their product faster, have a higher feeling related to the product, and make you get that ever popular placebo effect. I think most people know that nothing works in one pill so they always give you at least two as the dosage (think about Tylenol, 2 pills). If that's the dose, just make it one big one, right? Well this one tells you to take 4 pills. Crazy. Here's what I do. I take one every morning, whether I work out or not. Then I take another one about an hour before I work out. Then once I do that for a week, I see how I feel and consider upping the dose. In my case I found that two in the morning and two before I work out was about right. If I don't work out, I only do the two in the morning. My reason is that I want it to be in my system to start the day but then I want it to be available before my workout. I don't take all at once nor the full dose before a workout because I want a slight pump from the NOX then a big pump from the workout itself. Think about it, if you can get a pump by just taking this it's not helping you work out. But the placebo effect does play a part for some so if you take it for that reason, to get that pump regardless, then you might want to take the full dosage. In my opinion I would not take the full amount for many reasons but mostly because vasodilators can mess with your system if you're not careful. Most notable is if you have blood pressure problems. If you're on medication or have heart issues don't take this. Stick with doc recommendations. While this isn't dangerous, per say, it's not something I would want to roll the dice on. Also, to address the placebo effect a bit more clearly. Almost everything can help you boost gains if you think you could boost gains. And in this case, you can drink a ton of water and get a similar pump effect, but I think that this, combined with water intake and creatine is one of the safest ways to get in better shape. And even if I'm wrong, you still get some pretty interesting boners. So if that's all you get, it's not a total loss. Just remember that with great boners come great responsibilities. Review: Works better than advertised - I haven't been able to lift for my upper body since hand surgery. In the past after above the waist surgery my upper body begins to lose definition, and my chest looks terrible. I have been pleasantly surprised, because my chest definition has remained basically the same. It works better than advertised. ## Features - ABOUT THE PRODUCT: GNC AMP Ultra Nox is a fully-dosed formula delivering the stimulant-free fuel needed to support intense muscle pumps, endurance, and energy production Train harder with our advanced complex, designed for ultimate performance - ADVANCED ENERGY: Take your workouts to the next level This advanced formula helps maintain your physical activities for longer, so you can crush your workouts with little to no fatigue while maximizing NO Production & Blood Vessel Tone - CLEAN ENDURANCE: GNC AMP Ultra Nox has a non-stimulant, superior fatigue-fighting formula for added energy plus vitamin B12 to maintain healthy blood and nerve cells - FORMULATION: GNC AMP Ultra Nox contains 15g L-citrulline and a nitric oxide enhancer to help fuel your body's NO cycle for increased power during intense training Take 4 tablets daily with 8 fl oz of water or sports beverage 30-60 minutes before your workout as a dietary supplement On non-training days, take first thing in the morning - ABOUT THE BRAND: For over 85 years, GNC has been the leading global health and wellness brand providing the best in performance inspired nutrition We are committed to meeting the highest standards while applying the most up-to-date advances in nutritional science Above all else, GNC aims to inspire people to live well ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07BPMTYJH | | ASIN | B07BPMTYJH | | Age Range Description | Adult | | Best Sellers Rank | #96,792 in Health & Household ( See Top 100 in Health & Household ) #426 in Sports Nutrition Endurance & Energy Supplements | | Brand Name | GNC | | Customer Reviews | 4.6 4.6 out of 5 stars (252) | | Date First Available | June 16, 2018 | | Dosage Form | Tablet | | Flavor | Unflavored | | Item Dimensions | 1 x 1 x 1 inches | | Item Form | Tablet | | Item Weight | 6.4 ounces | | Item model number | 988711 | | Manufacturer | GNC | | Manufacturer | GNC | | Manufacturer Part Number | 988711 | | Model Number | 988711 | | Number of Items | 1 | | Primary Supplement Type | vitamin A, vitamin C, vitamin D, vitamin E, B-complex (B1, B2, B3, B6, B12), folate, biotin, zinc, magnesium | | Product Benefits | Supports overall health and wellness | | Product Dimensions | 1 x 1 x 1 inches; 6.4 ounces | | Specific Uses For Product | Supports overall health and wellness | | Total Servings Per Container | 120 | | UPC | 048107176662 | | Unit Count | 120 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** GNC - **Flavor:** Unflavored - **Item Form:** Tablet - **Item Weight:** 6.4 ounces - **Item dimensions L x W x H:** 1 x 1 x 1 inches - **Number of Items:** 1 - **Product Benefits:** Supports overall health and wellness - **Unit Count:** 120 Count ## Images ![GNC AMP Ultra Nox, Supports Endurance & Performance, Stim-Free, 120 Count - Image 1](https://m.media-amazon.com/images/I/71ZZ3zW9SQL.jpg) ## Questions & Answers **Q: Smoker and slightly overweight.

In the past after above the waist surgery my upper body begins to lose definition, and my chest looks terrible. I have been pleasantly surprised, because my chest definition has remained basically the same. It works better than advertised. ### ⭐⭐⭐⭐⭐ It works *by P***M on March 17, 2026* I was a long-time user of Cellucore N03 Chrome, but it's impossible to get, or it's been discontinued, so I gave GNCs a try. Overall, just about the same results and effects. Works great. ## Frequently Bought Together - GNC AMP Ultra Nox | Supports Endurance & Performance | Stim-Free | 120 Count - GNC AMP Creatine HCl 189 Pills, Clinically Proven Strength & Muscle Builder, Athletic Performance, Energy Production, Recovery Supplement, Fast Absorbing, Gluten Free Formula, 60 Servings - GNC AMP Men’s Extreme Training Vitapak Program, 5 Products in 1, Convenient Vitamin Pack for Performance & Endurance, Adult Multivitamin, Proven Ingredients, Caffeine, Nitric Oxide, 30 Day Supply --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/65945256-gnc-amp-ultra-nox-supports-endurance-and-performance-stim-free](https://www.desertcart.com.ar/products/65945256-gnc-amp-ultra-nox-supports-endurance-and-performance-stim-free) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
