Has any one used Myostatin blockers? Do they work? Are they safe? For those who don't know, Myostatin is a natural protein in the human body that limits muscle growth. Studies done on lab rats indicated a near doubling of muscle size (they found a way to block the gene). And in 2000, a kid in Germany was born that has this condition. Basically he has twice the muscle and 1/2 the fat of a normal kid, but he is like 2 times stronger than average and he appears healthy. Supposedly there are drugs on the market that help block the production of Myostatin in the body. Another question I have is if steroids do the same thing (block myostatin)? Or is there a safer product available than steroids?
