Big fan

Always trust this brand when it comes to quality and taste. This always helps my workouts, I feel the increase energy and I see the results from this. I take this routinely everyday 20 minutes before my workout and see the benefit as prescribed. The package is always good, the spoon doesn’t get lost in the powder. One scoop is the dosage to get the max efficiency.

It combines a pump effect with fat burning, instantly maximizing your workout performance!

GAT Nitraflex Burn, this pre-workout fat-burning supplement, truly amazed me. I remembered it after just one use; it's completely different from regular pre-workout supplements—the muscle pump during training is incredibly noticeable, the power output is sustained, and I feel energized from start to finish. The core ingredient, Nitrosigine, significantly improves the pump and focus, while CaloriBurn GP promotes thermogenesis and fat burning, essentially doing two things in one workout. I got the apple and honeydew melon flavor, which is very refreshing and not overly sweet. One scoop contains 325mg of caffeine; I recommend beginners start with half a scoop to test tolerance. This is perfect for those who want to burn fat and sculpt their body without sacrificing training intensity, and the price on iHerb is very reasonable. Definitely adding it to my repurchase list!

Great pre-workout for energy and focus. I feel more motivated and my workouts are more intense. Perfect before training when you need an extra boost.” Pre-workout formulas often help reduce fatigue and improve workout performance.

Very potent

Quality of product is top-notch. The taste is the light and not Surrey. It is great for the efficiency of your workout very potent. I recommend only doing half a scoop the first couple times until your body gets adjusted to the ingredient count. Does increase heart rate so be mindful of that.
