"Richard is believed to have been born with a defective gene which encodes the
myostatin gene. Normally, humans are born with a certain amount of muscle cells. The myostatin protein ("myo" for muscle, "statin" for static) prevents muscle cells from replicating in humans. A mutation in this gene, resulting in a mutated protein which no longer performs the proper function, allows Richard's muscle cells to replicate where normal humans cannot (normal muscle cells only grow with exercise, but do not replicate), thus allowing Richard to achieve his unique physique. With proper training, the definitions of his musculature are very visible."
B.S. He was on gear and now his dad is banged up hes not on gear anyomore and just looks like a normal kid. His dad refused to divulge the contents of Richards "secret shake recipe". Im guessing it went something like Whey protein,Dianabol,milk. It was probably the milk that made him big or his "special genes" yeah right.
