GNC AMP Ultra Nox, Supports Endurance & Performance, Stim-Free, 120 Count

Before you take these, if you haven't had NOX type products, what this does is it increases the size of your veins making them larger. 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.

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.

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.

This is a really good product and with all of the store closures. It's difficult to find a store this simplifies the process.

Product works as advertised. Great pre-work out formula for good pumps and foxus at the gym! This product delivers just what you would expect without any caffeine!!

I used to be an avid user of the MRI products until they dropped the ball, so I know what it feels like when the stuff works, and this does. The telltale sign of vasodilation, besides extra workout strength, is the Viagra effect. 4 a day is a good dose, though I divide it out 2 in the morning and then 2 before workout.

Muy bueno mucha energía

Not what had hoped for. Everyone’s body make up is different- perhaps my age and dna was a factor.
