THE SCIENCE BEHIND SHUT•EYE
SCIENCE PROVES YOU NEED MUSCLE SLEEP IF YOU WANT TO GROW.
SHUT•EYE is a patented and human clinically proven, non-habit-forming, muscle-sleep inducer.1 Muscle sleep is a bodybuilder must, and so is SHUT•EYE. Muscle sleep can happen approximately five times throughout the night. Muscle sleep can happen within 90 minutes after you first go to sleep and it lasts for 10 minutes. Throughout the night, each successive phase of muscle sleep can last longer and longer. If you achieve the final occurrence of muscle sleep, it can last for up to one hour. But if you aren’t achieving muscle sleep, you’re not maximizing your growth. That’s why SHUT•EYE is so vital.
The white bars on the graph below are the times during your sleep cycle you build the most muscle — this is called muscle sleep. Muscle sleep means muscle growth 2.

The following illustrates the bodybuilding benefits of achieving muscle sleep that SHUT•EYE provides.
