Vialox vs Semax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
- Half-Life
- Not applicable (topical; effect duration hours)
- Minutes (but effects persist for hours via BDNF induction)
- Admin Route
- Topical
- Intranasal, SubQ
