MRI: Medical Research Institute - NO2 Black Nos-Enhanced Hemodilator - 300 Caplets

MRI: Medical Reaseach Institute NO2 Black Nos-Enhanced Hemodilator offers tremendous benefits to athletes and bodybuilders seeking “next level” gains in size and strength. In the “dark ages” before the introduction of NO2 BLACK, inducing long – lasting vasodilation was unheard of. In those days, athletes would supplement with L-Arginine with only marginal results. Here’s why. L-Arginine certainly functions as the “fuel” for N.O. production; however, it’s the “factories” that convert L-Arginine into N.O. that are the real problem.

These “factories” are enzymes called “Nitric Oxide Synthase” (NOS) – and humans have a very limited supply of them. So, no matter how much L-Arginine we introduce into the system, its conversion into N.O. is completely dependent upon NOS availability. Fortunately, MRI found a way to “crack the code” of NOS up regulation with ACTINOS2. ACTINOS2 is a powerful whey fraction that multiplies the number – and activity – of NOS. More NOS equals far greater N.O. generating potential – 950% more to be exact. This unprecedented level of nitric oxide production requires a word more powerful than “vasodilation.” MRI calls this extreme flow of N.O. – induced blood flow “hemodilation.”

NO2 BLACK takes hemodilation a step further with the sustained release technology pHylex9. pHylex 9 disperses the premium AAKG, alpha lipoic acid and ACTINOS2 over time. The “trickle” of compounds promotes the now famous “perpetual pump” – the muscle-engorging surge of blood flow that can last up to hours. You see, “plain” L-Arginine triggers only a scant 2 – 3 second “blip” of N.O. – then its gone. By incorporating pHylex9 into the formula, premium Arginine AKG is slowly introduced into the system – allowing for ongoing N.O. production.

With the NO2 BLACK Full Cycle and NOS “Up-regulation,” you can experience ferocious gains in size and strength fueled by the incredible power of hemodilation.

Flash Recoveries
Your training is all about adding new lean muscle. And what "signals" the growth of that new muscle? Nitric oxide. So it stands to reason you want higher levels of nitric oxide maintained through extended periods of time. That's just what you get with NO2 Black. 950% higher levels than previously possible - sustained throughout the day! That's why thousands of bodybuilders - like you - are adding massive amounts of new muscle every day with NO2 Black.

"In-Gym" Muscle Recovery
Here's a scientific fact: The faster you start your recovery, the faster you add new muscle. With NO2 Black, you start to recover even before you leave the gym! How is this possible? MRI's new NOS Up-regulating technology - ACTINOS(2) - generates 950% higher nitric oxide levels. These "upper limit" levels of nitric oxide "hyper-dilate" the blood channels, driving vital recovery nutrients (like aminos and glucose/glycogen) to your muscles faster and in far greater quantities. And NO2 Black's extended-release technology ensures the continuous surge of those nutrients all day long. Even as you're lifting, the recovery nutrients are coursing to your muscle cells! If it weren't for the extended-release technology, NO2 Black wouldn't stand a chance of driving recovery because nitric oxide is a gas that becomes inert within 2-3 seconds. So the real key to nitric oxide's efficacy is MRI's pHylex9- extended release delivery technology.

Skin Ripping Pumps - Lasting into Tomorrow!
Every bodybuilder can tell you, you look your best right after a workout. It's when you're pumped to the maximum. It is the quick return on your investment of hard work in the gym.. Now with NO2 Black you can keep a good portion of that look into the next day!

And keep in mind, pumps do more than look great. They're living (and impressive) proof of increased blood flow delivering vital "growth nutrients" to your muscles. That's why with NO2 Black, you just keep making gains day after day! And gains that you keep!

At Last... Breaking the "NOS Barrier"

Up-Regulating "NOS" Enzymes Yields 950% N.O. Increase

Your body uses an enzyme called "Nitric Oxide Synthase" (NOS) to convert the arginine you supplement, or ingest, into nitric oxide. Two decades ago bodybuilders had only plain (not extended-release) arginine, today resurfacing as "fast" release nitric oxide generators. These products can be used as pre-workout boosters, but you will see little benefit in sustained muscle growth, pumps, and recoveries. That's because after arginine reacts with nitric oxide synthase to generate nitric oxide, you get a 2-3 second blip and the N.O. disappears. That's why MRI developed the original NO2 in 2002. That's when Arginine-AKG was placed in extended-release formula. Suddenly, users saw very good results. Now, 5 years later, for the first time with NO2 Black's "NOS Up-regulation," you have the "upper limit" levels of nitric oxide (950% greater) extended throughout the day! Now you can experience ferocious gains and watch your physique transforming from day to day!

ACTINOS(2): NOS "Up-Regulating" Technology
NO2 Black "Up-regulates" (creates more of) the body's NOS enzymes. NOS enzymes are what convert arginine into nitric oxide. Before NO2 Black, the body's limited amount of NOS prevented full generation of nitric oxide. But now with the added NOS, NO2 Black breaks the "NOS barrier" - creating 950% higher nitric oxide levels than historically possible. This sustained explosion of nitric oxide is what gives you the never-before-seen type of results.

Breaking the NOS Barrier
Before NO2 Black, there was a natural "limit" to the amount of nitric oxide the human body could generate. That placed a limit on the results you could expect. Now, thanks to ACTINOS(2) - MRI's new NOS Up-regulating technology – NO2 Black is able to break the NOS Barrier - obliterating the previous limit of nitric oxide.

Physiological Change – Starting Today
We're finally witnessing the sheer physiological power that these upper limit levels of nitric oxide exert on your gains. With 950% higher levels than previously possible, no wonder users are reporting the biggest gains of their training lives. The best part is, you'll see and feel the overwhelming effects of NO2 Black after your first dose. The quick effect is attributed to ACTINOS(2)'s ability to quickly react with arginine alpha-ketoglutarate – so you feel a rapid shot of energy.

pHylex9- Patented Extended-Release Delivery Technology
NO2 Black employs MRI's famous pHylex9 delivery technology for hours of sustained release arginine-alpha ketoglutarate, alpha lipoic acid, and ACTINOS(2).
