Vialox- Summary
- Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
- 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
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- Not applicable (topical; effect duration hours)

- Key Benefits
- Induces autophagy — cellular self-cleaning
- Extends lifespan in yeast, flies, worms, and mice
- Reduces cardiovascular aging and arterial stiffness
- Reduces all-cause mortality (human epidemiological data)
- Neuroprotective: reduces amyloid and tau pathology
- Promotes hair growth (anagen phase activation)
- Reduces age-related immune decline
- Improves memory in aging models

- 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
- Rare: mild GI discomfort at high doses
- May temporarily reduce some gut bacteria species
- Rare: headache at initiation
- Generally very well-tolerated topically
- Rare contact sensitivity or mild irritation
