Reported by top bodybuilders like Mr. Olympia runner-up Phil Heath and the world’s most muscular bodybuilder Branch Warren to be one of the best muscle building supplements, each dose delivers a key ingredient shown to build muscle and increase strength fast.
Third-party research, conducted at a leading university with 22 untrained subjects divided into three groups, which was published in Medicine & Science in Sports & Exercise, showed test subjects that consumed a key muscle building compound in naNO Vapor® Hardcore Pro Series™ with training gained 7.12 lbs. of muscle while subjects using a placebo with training gained 1.30 lbs. after 12 weeks.
In a separate third-party study on 31 weight-trained subjects divided into three groups, subjects using the same key muscle building compound used in the study mentioned above increased their strength capacity on the bench press by 18.6% compared to baseline in 10 days (6,658 vs. 5,613 joules). This test was performed using 70% of the subjects' one-rep max bench press. Repetitions were counted to the one-half repetition and the results were multiplied by force exerted and distance traveled and then converted to joules.
