Max Marchione(@maxmarchione):This is a dog with a myostatin deficiency, which roughly doubles its muscle mass. Myostatin is a protein every mammal makes to stop muscle growing past a certain point. There are now drugs in human trials that block myostatin on purpose to stop people from losing muscle with age or on GLP-1s. I think myostatin inhibitors may end up as one of the biggest drug classes of the next decade.
