With huge shoulders, gigantic quads, and an extremely buffed body, these animals look like they have been hitting the gym every day. But it’s not the case. These animals didn’t achieve their muscle mass by lifting weights or doing punishing strength training. The amazing muscle growth is because of the protein called myostatin, also known as GDF-8.
This particular protein is responsible for the rate of muscle cell production in an animal. Some of these creatures let their muscle mass increase naturally while others have their myostatin manipulated in order to achieve tremendous muscle growth.
See for yourself the effects of myostatin on various animal species through the photos below.
