The Power of the Pump

The pump…It’s one of the most rewarding feelings you can get from an intense training session. That tight sensation, that swell from blood rushing to the site of the working muscle... It is your green light-- a signal you're performing the right routine and following a diet that optimizes muscle growth. Put simply, pumps indicate you’re about to level up.

Nitric Oxide (NO): The Not So Secret Weapon For Next Level Pumps

Nitric Oxide supplements have been the weapon of choice for maximizing the pump. Essentially, Nitric Oxide helps promote blood flow to the muscles, which in turn supports a better pump.

NO3 Chrome utilizes NO3 in the form of Arginine Nitrate—a fusion of L-Arginine and Nitrate. Combining these two efficient and powerful ingredients helps give you the long lasting, unbelievable pumps to help your muscle gains.*

NO3 Chrome has been THE pump product for years, and to keep raising the bar we’ve explored new ingredients to help take you to greater heights. We’ve armed the Fourth Generation of NO3 Chrome with Nitrosigine®, to help boost NO levels, and promote better blood flow for longer laster pumps.*

I’ve been combining l-arginine and beet oxides for years. I’d say this product takes it to another level for my body. Everyone is different and our diets coupled with aggression during workouts will make or break this product. Chest and biceps veins really open up on this NO3. It recommends 60-90 mins before workout, but I find it best to swallow with my pre workout drink and hit the weights hard immediately.

Noticeably more muscular endurance which is nice, but I noticed ZERO extra pump/vascularity with this product. I'm 5'6 135lbs, 6% body fat, and have been an athlete for more than 10 years, so I know when I have a product that's complete bogus that emphasizes "skin ripping pumps".

This product is really great. A friend suggested me and I tried it for the first time last month and will buy it again. It gives you a nice pump when training and makes me feel better during the workout session. I only took it on gym workout training days.

I was a little disappointed in this actually. I've taken NO products in the past and I seemed to get a better pump with them. I thought it would be better than it was, just didn't get the pump.

I've been working out for years and I have used Nitric Oxide before, I took it on empty stomach and like 70 - 80 min prior to start working out and I didn't experience ANY pumps... I quit taking it during the 3rd week of continues use since I was hoping to feel something after some time... but nothing !! I don't know if it's me but I wasted my money.

total waste of money. I started off with 3 then went up to 6 pills and still felt nothing. Not worth it

I love this product so far! The pump factor is decent but not necessarily any better than other NO products I've used over the years, BUT this product gave me an unintended side effect. I don't know if it's just a fluke for me but it's really changed what goes on down there in the "Men's Health" region. From realistic dirty dreams and waking up to fullness, and just natural blood flow increases. That's never a bad thing! :-D I'm surprised I don't see many others posting the same here!

Excellent pump, but side affects were not worth continued use. I've taken NO products in the past and have never had the shortness of breath experienced with this product. I had the same results when only using 1 pill, rather than the recommended 3. I did not experience any tingling or flushing that I've had with other products. I'd give a better rating if it weren't for the shortness of breath. I discontinued use and no longer experience this.

The pump after using this product was the best that I've gotten from any product I've tried in years!

I have tried numerous Nitric Oxide supplements. Although this product is a bit pricy, it does a great job

This is by far my favorite Cellucor product. I take it approximately 60 minutes prior to the start of my workout, then chase it with C4 about 10 minutes before the gym, and the combination is just lights out. My workouts are generally 50-60 minutes long, and I definitely feel a difference walking out of the gym when I'm on the NO3. The blood flow and pumps in the areas I'm working really help with the mental feeling that it was a great day at the gym.

I am stacking this with Mr. Hyde and although I have noticed a slight change in the pump, it's not enough for me to shell out the 40 bucks again.. Not unless it takes time to activate. I'm pretty muscular so I'm sure I would have noticed if it were a big difference. I've been taking the recommended dosage of 3 capsules an hour before working out (as suggested) with Mr. Hyde.
