An incredible video of two huge muscled bulls walking in the field became a hit on social networks. With the huge muscles and veins that pop up, it seems that this animals are just ready for a bodybuilding competition.

As published, this clip immediately divided the users of social networks, as some have suggested that the incredible muscles in these bulls are the result of steroid abuse or even genetic mutations.

It is known that some people use anabolic steroids when it comes to growing domestic livestock to make their meat more fibrous, but there are races like Belgian Blue which has even twice the muscle mass of its kind because of the gene that inhibits hormone myostatin.

This genetic anomaly is not related only to the bulls. A dog named Wendy with the same genetic mutation became made it to the headlines in 2007 because of its amazing muscular build.

Examples of such mutations have been seen in humans too. Ten years ago the New York Times published the news about the boy from Germany who was born with twice as much muscle mass than the average newborn. Mutations in the human myostatin gene results in individuals that have significantly more muscle mass and hence are considerably stronger than normal.

An American boy born in 2005, Liam Hoekstra, was also diagnosed with a clinically similar condition but with a somewhat different cause his body produces a normal level of functional myostatin; but, because he is stronger and more muscular than most others his age, his doctors believe that a defect in his myostatin receptors prevents his muscle cells from responding normally to myostatin. Liam appeared on the television show World's Strongest Toddler.

Imagine if one day the scientists could be able to extract the myostatin inhibitors in order to improve the human species. Ordinary people would become bodybuilders and anabolic steroids would lose their purpose.
