Anxiolytic PeptideLast Updated: April 1, 2026
Selank (also known as TP-7) is a prominently researched experimental compound classified strictly within the Anxiolytic Peptide framework. Operating primarily through advanced pharmacological pathways, it functions by modulates GABA/serotonin neurotransmitter systems. Enhances immune function by influencing IL-6 and T-helper cell balance. Stabilizes enkephalin levels. with a documented biological half-life of roughly 0.5 hours, in preclinical investigative trials and independent academic studies, researchers utilizing Selank have documented significant, quantifiable biological outcomes, primarily focusing on anxiety reduction, mental clarity, mood. Typical research protocols investigate administering 300 to 300mcg via nasal pathways 7x/wk. However, it is critically important to understand that while Selank demonstrates profound physiological potential in highly controlled laboratory settings, it remains classified strictly as a research chemical and has not been approved by the United States Food and Drug Administration (FDA) for human therapeutic, diagnostic, or dietary consumption. Independent chemical analysis via rigorous third-party Certificate of Analysis (COA) testing utilizing High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) remains the industry gold standard for verifying its base elemental stability when reconstituted appropriately in sterile bacteriostatic water.

Clinical trial demonstrates Selank's anxiolytic efficacy in patients with generalized anxiety disorder, comparable to benzodiazepines but without sedation or dependence.
moderateStudy confirms Selank provides significant anti-anxiety effects comparable to benzodiazepine treatment, with added cognitive enhancement and no addictive potential.
moderateSelank increases BDNF production in the rat hippocampus and prefrontal cortex, preventing ethanol-induced memory impairment and enhancing synaptic plasticity.
preclinicalMolecular study showing Selank influences GABA-A receptor subunit gene expression, providing mechanism for its anxiolytic effects without sedation.
preclinicalVery safe profile. No reported dependence or withdrawal. Approved as anxiolytic in Russia. Not FDA-approved in US.
