Selank vs MOTS-c

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

Cognitive Enhancement
Selank
Anti-Aging & Longevity
MOTS-c
Summary
Selank is a synthetic heptapeptide analog of tuftsin developed in Russia. It is a potent anxiolytic that reduces anxiety and enhances cognitive function without sedation or addiction. It is approved for clinical use in Russia for anxiety disorders.
MOTS-c is a mitochondria-derived peptide (MDP) encoded within the mitochondrial genome. It acts as a metabolic regulator, improving insulin sensitivity, enhancing exercise capacity, and counteracting age-related metabolic decline. It is often called a 'mitochondrial hormone.'
