Syn-Ake
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.
Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.

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
  • Reduces depth of dynamic wrinkles and expression lines
  • Reversible muscle-relaxing effect on facial muscles
  • Smooths forehead lines, crow's feet, and frown lines
  • Non-invasive alternative to injectable neurotoxins
  • Rapid onset relative to collagen-stimulating peptides
  • Well-studied in in vitro and clinical cosmetic trials
Side Effects
  • Injection site reactions
  • Temporary nausea
  • Flushing
  • Elevated LH/testosterone (intended effect)
  • +1 more
  • Generally very well-tolerated topically
  • Rare skin sensitivity or contact dermatitis
  • Theoretical neuromuscular effects at systemic doses (not relevant topically)
