An excellent Muscle Building supplement by GetEnhanced. If you’re anything like me, you’ve spent a lot of time wondering why some people are naturally very muscular and others aren’t. Obviously, diet and lifestyle play a role but there is no denying the fact that there is also a major genetic component. Myostatin, a type of myokine protein is the main genetic component that regulates muscle growth potential. Genetically gifted bodybuilders have very low levels of myostatin in their bodies. Experiments where animals were born without myostatin grew muscle endlessly with little exercise. A number of supplements have been designed to inhibit myostatin production over the past 20 years, but none of them have been very effective – until now.
