AOD-9604 vs Vialox

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

Vialox
Summary
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.
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
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
  • Improved bioavailability over Fragment 176-191
  • GRAS (Generally Recognized As Safe) status in Australia
  • Potential cartilage repair and anti-inflammatory properties
  • Does not suppress natural GH production
  • 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
  • Localized injection site reactions
  • Headache (rare)
  • Hypoglycemia risk in combination with insulin (very rare)
  • Generally very well-tolerated topically
  • Rare contact sensitivity or mild irritation
  • No clinically significant systemic neuromuscular effects at cosmetic doses
