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.
Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.

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
  • Stimulates skin collagen and elastin production
  • Reduces wrinkle depth and improves skin hydration
  • Supports joint cartilage regeneration
  • Reduces joint pain in osteoarthritis
  • Promotes bone density (stimulates osteoblasts)
  • Improves gut barrier integrity (leaky gut)
  • Supports hair and nail growth
  • Excellent amino acid profile for muscle recovery
Side Effects
  • Injection site reactions
  • Temporary nausea
  • Flushing
  • Elevated LH/testosterone (intended effect)
  • +1 more
  • Excellent safety profile as food-derived protein
  • Rare: bloating or GI discomfort at high doses
  • Rare: allergic reaction (bovine or fish allergy)
  • Mild bad taste (some forms)
