Kisspeptin-10
Anabolic & IGF
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.

Key Benefits
  • Potently stimulates LH and testosterone
  • Enhances sexual arousal and libido
  • Activates HPG axis — upstream of GnRH
  • May improve fertility in hypogonadotropic hypogonadism
  • Increases brain activation in sexual attraction circuits
  • May restore LH pulsatility in suppressed HPG axis
  • Inhibits myostatin — removes muscle growth ceiling
  • Significant increases in muscle mass and strength
  • Reduces fat mass
  • Promotes bone density
  • May stimulate hair follicle cycling
  • Anti-fibrotic effects in muscle tissue
  • Synergistic with IGF-1 and other anabolic peptides
Side Effects
  • Injection site reactions
  • Temporary nausea
  • Flushing
  • Elevated LH/testosterone (intended effect)
  • +1 more
  • Muscle soreness (from rapid hypertrophy)
  • Potential reproductive effects (activin inhibition)
  • Unknown long-term safety profile
