Build strong lean muscle and recover quicker from injuries
GDF-8 binds to myostatin and prevents it from activating so that it can’t attach to its receptors. Myostatin-binding receptors usually inhibit muscle growth, but because GDF-8 prevents myostatin from binding, growth is unhindered.
When myostatin is absent, both humans and animals gain significant amounts of muscle mass.
Myostatin deficiency has also been linked to increased bone mineral density.
In addition, when tested on a model of tissue injury, animals treated with GDF-8 showed increases in muscle and bone repair. These findings suggest that GDF-8 may one day be used to repair damaged muscles and bones.
