Ehh

[This review was collected as part of a promotion.] Pills have no smell or taste. Bottle was easy to open. Dosing is too much for me, 3 pills is a lot to take. I have not noticed any difference since I started taking them

Very good

[This review was collected as part of a promotion.] Its packaging and smell are phenomenal and its taste is nothing to talk about, nor do I feel if I recommend it to my mother and other people who also need dosing.

Need more time

[This review was collected as part of a promotion.] These are good so far but still need more time for result. No bad taste after taking but slight stomach ache at times. The look is deceiving and it's not easy to remember to take.

They gave me little bit more energy

[This review was collected as part of a promotion.] They don't have bad after taste when you take them. They gave my little bit more energy. Looked up the price it's not bad at all. I will keep taking them

Heart Healthy

[This review was collected as part of a promotion.] Doctors Preferred Nitric Oxide Advantage does give me extra energy. You take 3 tablets once daily and you get 90 tablets. I love that is Herat healthy. Definitely will buy again. Recommend it!

Effective for a good pump

[This review was collected as part of a promotion.] I've used nitric oxide before for some workouts, so I was excited to try these out. They were easy to consume and I could honestly tell the difference at the gym and felt like I got a good pump.

You could try it

[This review was collected as part of a promotion.] This was a nice item to have. It had clear instructions on the bottle. I personally can't take this item but I gave it to others and they noticed a difference
