Feel ready to lift without getting the jitters
I'm a fan of these. I definitely can feel myself feeling ready to lift and squat heavy stuff when I get to the gym. I have to say my absolute favorite thing about these are that they are in pill form! No need to mix anything is so convenient. Will for sure buy again. And customer service for this company is beyond AMAZING!

    I use this not only for gym workouts, but for sexual circulation and the anti aging benefits of pine bark. To buy 2000mg of l-Arginine and 200mg of pine bark separate it would cost more then double. Google: health benifiits of Pycnogenol (the US patient standardaized brand) and you will find impressive medical studies of the anti oxidant benifits of pinebark. Although it’s not Pycnogenol (French maritime pinebark), it’s Pinus Pinestar - which is also maritime pinebark. Both Life Extension brand and Solgar sell the same amount of pinebark for $50 a bottle! W out the L Arginene. I’m assuming they can’t brand it this way without a serious cost increase due to FDA and marketing. Many studies on this exact combo increments on 60 day subjects with 90% ED correction.. Great buy!

    So far, so good. I have been taking now for about 2 1/2 weeks and I feel that I can tell a difference during my workouts. I seem to have more energy thru out the day as well.

    After a month on the product, I can now say that the product works as described. It does seem to increase the intensity of your work-outs and does give you the extra kick to power thru one or two more sets. My only complaint is that it takes about an hour to start kicking in, and since I workout in the AM, I'm not getting the full effect till late into my workout...not a complaint against the product per se, just something to be aware of.

    Overall, I have been pleased with the results I have been getting from Top NO2

    Took the whole bottle and it had no effect
  • Reviewed in the United States on December 15, 2017
    Maybe it was just my body, but I've never used N.O boosters in my life, nor do I drink caffeine. So when I first bought the product, I figured it would be too much to take 4 pills (recommended) at once. The first day I tried 2. Felt nothing. Then 3 the next day. Then 4 the day after. Still. Felt nothing. But I took 4 every day anyways because maybe later on I'd probably feel something or maybe notice a difference in my workouts. But honestly, I felt the same as I would if I hadn't taken anything. So I just give it a nuetral review.

    Amazing stuff. I use it for anti-aging. Nitric Oxide declines after 40yo and at 72 I know that for a certainty. Currently I take one of these three times a day and everything just is so much better. I was so exhasted the other evening that thinking about setting up the coffee pot to make coffee the next morning seemed like an insurmountable task! It had been a long day. I took once capsule of this product and after a half hour or so I had so much energy it was incredible. I not only set up the coffee but I broke out the laptop and did some work. One caveat is that it will keep you awake so have to stop taking it a few hours before bedtime.

    N.O. works great! I lift weights everyday, and I experience endurance with minimal muscle fatigue and no jitters as in caffeine. I highly recommend this product.
  • Reviewed in the United States on October 9, 2016
    I am 51 and have been trying to get a routine workout started for months. I just kept getting frustrated because, after 5 years off, my lift totals are WAY off. My bench plummeted from 315# to struggling at 155# (and I am an overweight 260 which adds to my frustration). In one bottle, my bench just clipped 215#--that is in one month--and my squats have gone from just press machines to actually doing 5x15 @225#. I am still overweight, but we are working on it. Even the folks in my Mon-Thur circuit training class have noticed a change.
