Melanotan II vs Vialox

Side-by-side comparison of key properties, dosing, and research.

Sexual Health & Libido
Melanotan II
Skin & CosmeticAnti-Aging & Longevity
Vialox
Summary
Melanotan II is a synthetic analog of alpha-melanocyte-stimulating hormone (α-MSH) that stimulates melanin production (skin tanning), suppresses appetite, and enhances sexual function. It is not FDA-approved and has significant safety concerns including mole changes and cardiovascular effects.
Vialox is a synthetic pentapeptide that mimics the activity of conotoxin from cone snails, acting as an antagonist of nicotinic acetylcholine receptors at the neuromuscular junction. Similar to Syn-Ake but derived from cone snail venom biochemistry, it reduces facial muscle contraction to smooth expression wrinkles.

Key Benefits
  • Promotes skin tanning and melanin production
  • Reduces UV exposure needed to tan
  • Enhances libido and sexual function
  • May suppress appetite
  • Faster, deeper tan development
  • Longer-lasting tan maintenance
  • Potential photoprotective effects
  • Reduces dynamic wrinkles from repetitive facial expressions
  • Reversible muscle-relaxing effect without injection
  • Smooths forehead, periorbital, and perioral lines
  • Complementary to collagen-stimulating peptides
  • Well-studied tolerability in cosmetic concentrations
  • Can be combined with Syn-Ake for dual conotoxin/viper venom effect
Side Effects
  • Nausea (very common, especially in first days)
  • Facial flushing
  • Spontaneous erections in men
  • Darkening or changes in existing moles (monitor closely)
  • +3 more
  • Generally very well-tolerated topically
  • Rare contact sensitivity or mild irritation
  • No clinically significant systemic neuromuscular effects at cosmetic doses
