We offer peptides for sale as Peptides Follistatin 1 mg. Follistatin is a binding protein rather than a signalling peptide, and this Polypeptide listing supplies 1 mg. It works outside the cell: by attaching to selected growth factors before they reach their receptors, it reduces the signal those factors would otherwise deliver. Activin was the ligand that led to its discovery, and myostatin, also called GDF-8, is the one that drives most of the current interest.
Myostatin restrains muscle growth, so a protein that binds it is studied in muscle biology. That is a mechanism, not a result. Follistatin's binding profile is broader than the myostatin blocker shorthand suggests, and the downstream effects of reducing TGF-beta superfamily signalling are complex.
Not an androgen, not a secretagogue
Three categories get confused here. Anabolic steroids act inside the cell at the androgen receptor. Growth hormone secretagogues act at GHRH or ghrelin receptors to increase hormone release. Follistatin does neither: it modifies the availability of extracellular ligands. That is why testosterone comparisons miss the point of the molecule.
Follistatin is described in the literature under more than one numbering: the 344- and 317-residue entries refer to the precursor, while the 315- and 288-residue entries refer to mature forms, and those mature forms differ in heparin binding and tissue distribution. The name itself comes from the function for which it was first identified: inhibition of follicle-stimulating hormone release. Different numbered forms are molecularly distinct; the amount alone does not identify one.
