You may think you've been training hard and your regular pre-workout formula is getting the job done.

Its scientifically advanced power is unprecedented. It's a nitric oxide pre-workout formula designed with scientifically studied key ingredients shown in scientific research to build eight times more muscle, instantly increase strength and change your training experience on your very first dose! It's one thing to feel something happening when you take your pre-workout supplement, but it's another story altogether when you're supplying your muscles with the exact amounts of key ingredients shown to build muscle in published research. Case in point - just two of the multiple key ingredients in the new naNO Vapor Hardcore Pro Series formula are shown to help test subjects gain eight times more muscle than control subjects in just eight weeks (3.72 vs. 0.41 lbs.)!

Directions For MuscleTech NaNO Vapor Hardcore Pro Series: naNO Vapor is extremely powerful, so do yourself a favor. Start off by mixing 1 scoop (1 serving) with 3 to 4 oz. of cold water and downing it about 15 minutes before hitting the weights. Then, grab something heavy. As you develop respect for, and understand the power of naNO Vapor, you can gradually increase the dosage to 2 to 3 scoops (2 to 3 servings) mixed in 8 to 12 oz. of cold water before working out. For maximum results, consume on an empty stomach. Do not exceed 3 scoops (servings) in a 24-hour period. Due to the extreme reactivity of the naNO Vapor formula, made sure the container is stabilized for at least 10 to 15 seconds before opening the lid. Otherwise, nanoparticulated particles invisible to the naked eye may escape the confines of the container. Do not leave the container open for more than 30 seconds. Due to the unbridled power of naNO Vapor, make absolutely certain that you have read the entire label before using naNO Vapor. You must precisely follow the directions provided.
