your born with it
When you see your baby abs showing a little at that age and muscle on the back and arms. You will see that they have myostatin. When you don't see any. When they are one years old let them do one chin up and when they can they are myostatin.
"MY-OH-STAT-IN"
Myostatin is the protein that is secreted to initiate growth. It effects the muscles because it inhibits muscle differentiation and growth.
Myostatin is a protein that is in the human body. It is specially encoded by the MSTN gene and is usually in the skeletal muscle cells to inhibit muscle growth and differentiation.
It is found in the skeletal muscle of mammals.
Myostatin is a protein which is found in certain persons. It is made in the cells of muscles, and is carried through ones blood stream where it attaches itself to other muscles. From there, it inhibits their growth.
My human physiology is a bit rusty but if I remember correctly hormone supplementation can inhibit the body's ability to produce that hormone on its own. So my question is this: could supplementation with myostatin (GDF8) effect (read: lower or shut down) the body's ability to produce the hormone on it's own?
I have heard that it can be a symptom, but it doesn't MEAN you have an iron deficiency.
Mental deficiency...
It has a vitamin deficiency.
Deficiency means when you lack something for e.g There diet is deficient in vitaminsThe correct spelling is deficiency. The meaning of deficiency is a shortage or a lack. It can also mean a shortcoming or a failing.
