Semax vs Syn-Ake
Side-by-side comparison of key properties, dosing, and research.
- Summary
- 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.
- Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.
