A naturally occurring protein that binds and inhibits myostatin and related TGF-beta ligands, which in animal and gene-therapy models drives muscle growth. Cross-shopped with the IGF-1 / MGF / PEG-MGF muscle cluster. Most muscle-growth evidence comes from gene therapy and animal work; injectable follistatin-peptide products have essentially no controlled human efficacy data, so muscle benefit in people is unproven.
