Follistatin 344- Summary
- Kisspeptin-10 is the biologically active C-terminal decapeptide of kisspeptin, an endogenous regulator of the reproductive axis. It acts upstream of GnRH to potently stimulate LH and testosterone release, and plays a key role in sexual arousal and libido.
- Follistatin 344 is a recombinant form of the endogenous follistatin protein. It inhibits myostatin and activin — the primary negative regulators of muscle growth — potentially removing the genetic ceiling on muscle development. It is one of the most theoretically powerful anabolic compounds but is experimental with limited human data.
