IGF-1 is a major key to health and wellness. Siorai Regulator signals your body to make its own IGF-1 at the correct and balanced amount. Your body makes its own IGF-1 and overtime IGF-1 production goes down. Lower levels of IGF-1 result in poor health, inflammation, sluggish immune system, brain fog, fatigue, and decreased muscle mass. Conversely, adding too much IGF-1 can overload the system. Restoring a balanced IGF-1 is the key to feeling better.
