I have just recently heard about what is known as the myostatin inhibitor. Myostatin, for those who don’t know, is a protein that inhibits the growth of muscle/proliferation of skeletal tissue. There are photos out there of cows with a genetic modification that stops them from producing myostatin and allows them to get very... beefy.
I searched online and found a few companies that sell some myostatin inhibiting peptides. I’m completely clueless about this, about the legality, efficacy, etc. It seems like this would be a very powerful compound, if it is what they say it is. Any of you have experience with this or more knowledge?
