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. 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 – ACTINOS2 – 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 sure of those nutrients all day long. Even as you’re lifting, the recovery nutrients are coursing to your muscle cells! Every bodybuilder can tell you, you look your best right after a workout. It’s when you’re pumped to the max. It’s your "cover model" look. 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 growing day after day! Your body uses an enzyme called "Nitric Oxide Synthase" (NOS) to convert the arginine you supplement, or ingest, into nitric oxide. Humans naturally have very limited NOS, putting a "ceiling" on nitric oxide production. NO2 Black’s ACTINOS multiplies the number – and activity – of NOS, generating 950% higher nitric oxide levels than previously possible. Two decades ago bodybuilders had only plain (not extended release) arginine, today resurfacing as "fast" release nitric oxide generators. These products provided lower levels of nitric oxide. They were quick to release and quick to disappear. Users reported little benefit. In 2002, came NO2. That’s when Arginine-AKG was placed in extended-release formula. Suddenly, users saw very good results. Now, for the first time with NO2 Black’s "NOS Up-regulation," you have the "upper limit" levels of nitric oxide (950% greater) extended 24 hours a day! Now you can experience ferocious gains and watch your physique transforming itself hour to hour! 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 ACTINOS2 - MRI’s new NOS Up-regulating technology – NO2 Black is able to break the NOS Barrier - obliterating the previous limit of nitric oxide. Reaching Nitric Oxide’s "Upper Limit" Levels 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.
