If you want to feel energized and powerful, then this is the pre-workout supplement for you. This stuff will make you feel like you can lift an Abrams tank (you can lift 70 tons now, right?). And it WILL improve your strength and endurance.
This is basically a short-term creatine delivery drink, plus nitric oxide booster, plus caffeine (I’m dramatically over-simplifying this complex product). The bottom line is it’s not like creatine loading where you strain your system and flush tons of unused creatine through your kidneys. This is only for right before your workout.
I’ve used this enough to know it positively does work. I no longer use these types of products due to safety concerns. The problem with this product (and all similar ones) is when you cycle off, you will instantly realize the gains you made leave just as quickly as they arrived.
It does contain artificial sweeteners (it is aspartame free at least) and there really is no evidence to definitively prove that this or any similar products are safe for short or long term use. I personally believe that these products can cause high blood pressure. Many people develop a tolerance to this product and feel the need to take larger doses to get the same level of results.
If you’re going to take a pre-workout enhancer and you can tolerate caffeine, then this may be the product for you. If you are not an athlete and have no reason to endanger your body with unproven supplements, then I suggest you skip this one, because the gains it will help you make are only temporary.
