Amazing pre-workout! Studies showed that Nitrosigine is more effective than Citrulline in lower doses. 1.5 gram is the optimum dose for optimum muscular performance. Give me a good pump without the stimulants side effects. Also enhances your performance. My favourite pre workout supplement.

The packaging quality of this product is very good. The ingredients of this product are very good and it has an excellent effect on muscle gain after consumption. The pills are the right size and easy to swallow. The taste is good and I would like to purchase again next time.

Very effective product and a great compliment to their 1/2 immediate/half sustained release product. I intermittent fast every other day & on non-fasting days, I will take this product with my last meal prior to the start of fast (taking the sustained release product would delay my fasted state by a few hours). When I break a fast and early in the non-fasting days, I'll take the half/half product.

This product, combined with Ubiquinol, gives me real piece of mind. I love my sports and am in my 40s, so anything that can't assist with keeping my cardiovascular system healthy and optimized is a plus.

The packaging of this product is neat and good. I bought this product to see the effect of gaining muscle after diet and exercise. The taste was normal and easy to swallow. Will buy this product again next time!
