NutraBio Extreme Nitric Stack (Kiwi Strawberry)

Amazing pumps, taste and mixes great. I am using this for my pre contest prep to aid in recovery and give me energy without caffeine when carbs get low. This company makes the highest quality products out there. I even workout exclusively at my home.

This stuff gives me the best pump ever. I walk out of a work out probably 10% bigger than I was when I went in. The pump is only temporary of course, but I can tell there is significant vasodilation happening and my muscles are getting more nutrients to them. This product also seems to make more stronger and recover faster as well. I do add 5 grams of citruline malate to the mix though bc I feel like the quantity in this supplement is too low to see benefits. Overall this is my staple preworkout supp.

Good ingredients and great quality. Will buy again

Seems to flush the lactic acid out for faster recovery. I noticed it most when pushing my limits while mountain biking. I’m pretty in tune to how my body works and this seems to really work

I am a 52 y/o male who works out with light weights everyday. I was looking for a product that had a high dose l-arginine in it. I came across this product and saw that the other ingredients support muscle tone and help decrease muscle wear...in us middle aged types. I mix one scoop in 18 ounces of water, take 3 Nutrabio panax ginseng capsules, and start my workout. I do believe both products are helping with my work out and muscle tone. Take this, watch what you eat, do a walk video exercise...and you will see a difference. I did.

I don’t like the artificial colors and soy

Great PRODUCT. After a lot of research I settled on this and can't be happier!.

Love the brand but impossible to connect with customer service. I received the wrong flavor.
