Loved this product! Just starting taking this before my lifts and have definitely noticed a significant increase in muscle pumps throughout my workout. Definitely recommend this!

I use this product every single day before my workouts. I'll even use it twice a day if I'm doing fasted cardio in the morning. I can definitely notice the difference with blood flow with my pumps in my workouts and not only that when I'm doing cardio I just feel more energized than what I would be not taking that before cardio. If you're looking to maximize your cardio or your workouts, I would for sure recommend this product.

I use these capsules in the morning and in the mid day to help keep the "pump" feeling alive. I feel they work great but again everybody is not the same and what works for doesn't work for everyone. I use 2 capsules per serving and try to take them before or during my meal. During the days I workout I take a pre-workout with N.O. and that gives me the initial pump then I continue with the capsules. It's more of a personal preference to take these capsules just for the feeling of a pump.

Not Bad

Massive pumps and vascularity from using this product. Better to use capsules instead of tablets, as they digest much faster and get into the bloodstream much quicker. I pop three or four capsules and mix them into my preworkout and then add another few to my BCAA which I use during the workout. I am able to get a great pump, rock hard arms and road maps of vascular stems enabling me to push myself to the maximum and look great doing it. Essential part of my supplement regimen.

Ive been taking this product for about 3 weeks now and following the dosage as listed on the bottle and thus far the pump I've felt is underwhelming. I had taken this supplement initially by itself and within the last few weeks Ive added pre, intra and post workout supplements and during that time I continued to not feel a pump. I'm not saying this product is bad however as someone who had taken the original NO2 years ago I have yet to find anything that replicates the pump that it provided.
