Selank Deep Dive: Anxiety, Cognition, Immune System - Mechanisms, Risks, Forms, & Dosing

Selank is far more than just an anti-anxiety peptide - it's a synthetic heptapeptide derived from Tuftsin (a natural immune molecule in your body) that has been approved in Russia since 2009 and even made over-the-counter in 2017. But what does the science actually show? And how do its mechanisms, risks, and clinical data stack up? In this video, Dr. Quinn Stillson (MD + strength coach) breaks down the full science behind Selank: how it modulates GABA, glutamate, opioid, and monoamine systems to reduce anxiety, why its immunomodulatory Tuftsin-derived properties matter, how it compares to benzodiazepines, and what the Russian clinical studies actually demonstrate - while clearly separating evidence from speculation. 💥 Whether you're dealing with anxiety, brain fog, immune dysfunction, gut issues, or building a cognitive performance stack—this is the definitive deep dive on Selank. 🔬 In this video, you'll learn: ✅ What Selank actually is and how it was derived from Tuftsin ✅ Why Russia approved it as an OTC drug—and what that means for the evidence base ✅ How Selank modulates GABA, glutamate (NMDA), opioids, and monoamines for anxiolytic effects ✅ How Selank compares to benzodiazepines in head-to-head human studies ✅ Why Selank likely avoids tolerance and dependence unlike benzos ✅ Immunomodulatory, anti-inflammatory, and antiviral mechanisms ✅ Cognitive performance, memory, and nootropic effects ✅ Benefits for depression, adjustment disorder, pain, stroke recovery, and gut health ✅ Safety concerns, drug interactions, and theoretical long-term risks ✅ Intranasal vs. subcutaneous Selank—when to use each ✅ Optimal dosing for nasal spray and injectable forms ✅ Frequency and cycling strategies to maximize benefit and minimize risk ✅ Who benefits most from Selank—and who should be cautious 🎯 Best for: – Anyone dealing with anxiety, stress, or mood disorders – Those looking for a benzodiazepine alternative without dependence risk – Individuals seeking nootropic or cognitive performance support – People with autoimmune, inflammatory, or recurrent infection concerns – Those with gut symptoms tied to stress or anxiety – Clinicians exploring peptide-based psychiatric and immune therapies – Biohackers wanting an evidence-based breakdown of Selank 📍 Timestamps 00:00 Why Selank Is MUCH More Than an Anti-Anxiety Peptide 00:44 Selank’s Approval and Over-the-Counter Status in Russia 03:00 How Selank Was Derived from an Immune System Molecule (Tuftsin) 05:32 Immunomodulating Effects of Selank - Anti-Viral, Anti-Inflammatory, & More 07:19 Anti-Anxiety Mechanisms of Selank (GABA, Glutamate, Opioids, Serotonin) 11:38 Selank’s Studied Anti-Anxiety Benefits (Animal & Human Studies) 13:14 Selank vs Benzodiazepines - Tolerance, Dependence, and Side Effects 16:09 Cognitive Performance (Nootropic) Effects of Selank (Memory & Learning) 18:04 Other Mental Health Benefits of Selank (Depression & Adjustment Disorder) 19:28 Pain Reduction & Stroke Recovery with Selank 20:50 Gut Health Effects of Selank (Anti-Ulcer & Microbiome Regulation) 22:07 Risks & Safety Concerns of Selank (Tolerance, Dependence, Long Term Impact) 24:14 Possible Drug Interactions or Immune Dysregulation with Selank 26:05 Who Might Benefit from Selank?
