GDF-8, also known as Myostatin Propeptide, is a recombinant protein that binds and inhibits myostatin, studied in muscle-growth and regenerative research. It is supplied as a high-purity lyophilized powder in sealed vials for laboratory use. GDF-8 is investigated in research on muscle-mass regulation and myostatin signaling, and is commonly applied in cell-culture and preclinical studies. The lyophilized form provides stable reconstitution and reproducible experimental dosing.. Strict quality control is applied to every production batch, and we can supply batch-specific COA documents upon request. Unopened material should be stored sealed at 2-8 degree C in a dry, dark place; for longer storage -20 degree C is advised while avoiding repeated freezing and thawing. We support trial orders and large-volume supply, with OEM and custom private-label options and discreet worldwide shipping available. For research purposes only, not for human or veterinary use.
