Cognitive research peptides — Selank, Semax and related nootropic compounds. BDNF, neuroplasticity, anxiolytic and neurotrophic research at ≥99% HPLC verified purity.
Cognitive research peptides are among the most actively investigated compounds in modern neuroscience. This category covers the nootropic and neuroprotective peptides that cross the blood-brain barrier and modulate the central nervous system — Selank, a synthetic analog of tuftsin researched for anxiolytic and neuroplasticity effects without sedative or addictive properties, and Semax, an N-terminal fragment of ACTH researched for BDNF and NGF upregulation, attention enhancement and neuroprotective applications in stroke and ischemic models. Both compounds emerged from Russian neuroscience research programs in the 1980s-90s and are now studied internationally for cognitive performance, anxiety modulation, and post-traumatic neural recovery research. All cognitive compounds in our catalog are independently HPLC verified at ≥99% purity, ship with a batch-specific Certificate of Analysis, and are supplied as lyophilized powder with full reconstitution and storage guidance. The category is suited to research investigating BDNF expression, neuroplasticity, anxiolytic mechanisms, attention and memory pathways, and neuroprotective interventions.
Selank is a synthetic heptapeptide analog of the immunomodulatory peptide tuftsin. Research suggests it produces anxiolytic effects through the GABAergic system and serotonin pathway modulation without the sedation, dependence or memory impairment common to benzodiazepines.
Semax is a heptapeptide fragment of adrenocorticotropic hormone (ACTH 4-10) modified for stability. Research demonstrates significant BDNF and NGF upregulation, attention-enhancement effects, and neuroprotective applications in animal models of stroke, ischemia and oxidative neural damage.
Both Selank and Semax cross the blood-brain barrier and modulate central neurotrophin signaling. Combined neurotrophin upregulation, antioxidant pathway activation and neurotransmitter modulation make this category a key research tool for neuroplasticity and post-injury recovery investigation.
Selank emphasizes anxiolytic and immunomodulatory effects via tuftsin-pathway modulation, while Semax emphasizes neurotrophic enhancement (BDNF, NGF) and cognitive performance via ACTH-fragment activity. Some research protocols investigate them in combination.
No. Selank and Semax are pharmaceutical-grade research reagents intended for laboratory and pre-clinical research only. They are approved for limited clinical use in some Russian-federation jurisdictions but are not approved as medicines elsewhere.
Both compounds ship as lyophilized powder. Reconstitute with sterile bacteriostatic water by gentle swirling — never shake. Store reconstituted solution at 2-8°C and use within 30 days. Full reconstitution guidance ships with every order.
Cognitive peptides are studied across attention and working-memory paradigms, anxiety models (open-field, elevated-plus-maze), BDNF and NGF expression assays, and stroke / ischemia neuroprotection models. Most protocols involve intranasal or subcutaneous delivery in research preparations.
