🔹 IN-DEPTH SCIENTIFIC PROFILE
Selank is a synthetic heptapeptide derived from the C-terminal end of tuftsin, an endogenous tetrapeptide released by proteolysis of immunoglobulin G (IgG). It was developed in the same Russian laboratory responsible for Semax and shares its structural origin, but with a pharmacological profile oriented to anxiety and stress regulation.
Molecular structure:
- Secuencia: Thr-Lys-Pro-Arg-Pro-Gly-Pro
- Molecular weight: 813.9 Da
- Vida media: 30 a 60 minutos en plasma
- Routes: intranasal and subcutaneous
🔬 MOLECULAR MECHANISM OF ACTION
- Modulación GABAérgica: increases the sensitivity of GABA-A receptors without acting as a direct agonist, which explains its anxiolytic effect without sedation
- Regulación de serotonina y dopamina: balances both neurotransmitters in limbic regions associated with stress
- Inmunomodulación: retains the parent tuftsin's properties on macrophage activation and immune response
- Aumento de encefalinas: protects endogenous opioids from degradation, improving the stress tolerance threshold
- Modulación de BDNF: neurotrophic effect complementary to that of Semax
🧪 RESEARCH APPLICATIONS
- Trastorno de ansiedad generalizada
- Chronic stress and functional adrenal exhaustion
- Sleep disorders associated with anxiety
- Premenstrual syndrome
- Addiction recovery (especially alcohol and opioids)
- Immune system support under sustained stress
💉 RECONSTITUTION PROTOCOL
Reconstitution: 2 ml of bacteriostatic water in a 10 mg vial. Concentration: 5,000 mcg/ml.
⚠️ SAFETY CONSIDERATIONS
Excellent safety profile. No documented addictive potential. No withdrawal syndrome. Local injection site reactions or mild nasal irritation are the most common adverse events.
🧬 POPULAR STACK AND COMBINATIONS
- Cognition + stability: Selank + Semax (combinación clásica)
- Sleep + anxiety: Selank + DSIP
- Estrés crónico: Selank + NAD+ for additional energy support
