PGPIPN vs Vialox
Side-by-side comparison of key properties, dosing, and research.
- Summary
- PGPIPN is a bioactive hexapeptide (Pro-Gly-Pro-Ile-Pro-Asn) derived from beta-casein during enzymatic digestion. It exhibits anti-inflammatory properties via opioid receptor modulation and cytokine suppression, making it relevant for gut health, systemic inflammation, and as a component of casein-derived functional foods.
- 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.
- Half-Life

- Key Benefits
- Anti-inflammatory effects via cytokine suppression
- Gut mucosal protection and intestinal barrier support
- Opioid receptor modulation for gut motility regulation
- Potential analgesic activity via central and peripheral opioid pathways
- Explored for inflammatory bowel conditions and gut dysbiosis
- Natural origin (food-derived) with favorable safety profile
- 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
- Generally very well-tolerated given food-derived origin
- Theoretical opioid-mediated constipation at high doses
- Rare milk protein allergy in casein-sensitive individuals
- Generally very well-tolerated topically
- Rare contact sensitivity or mild irritation
- No clinically significant systemic neuromuscular effects at cosmetic doses
