About Myostatin

What it is
GDF-8, known as myostatin, is a naturally occurring protein of the transforming growth factor beta superfamily produced mainly in skeletal muscle. It normally limits muscle growth so muscles do not become too large, acting as a negative regulator. Loss-of-function changes in animals and rare humans cause increased muscle mass. Because it restrains growth, research targets blocking it rather than administering it.
How it works
Myostatin signals through activin type II receptors and SMAD proteins to suppress skeletal muscle cell growth and differentiation.

Key risk
None documented; this is the endogenous protein that limits muscle growth and is not administered as a therapy.
