[Source: Dolotov et al., 2006]\n\nA single intranasal dose increased BDNF protein 1.4-fold, TrkB phosphorylation 1.6-fold, and BDNF mRNA 3-fold in rat hippocampus, with improved conditioned avoidance (preclinical). [Source: Dolotov et al., Brain Research 2006]\n\nSemax increased BDNF mRNA up to 8-fold in murine glial cell cultures (preclinical).\n\n### Human Data\n\nOne referenced study in 110 post-stroke patients reported Semax raised plasma BDNF levels correlating with recovery metrics (human, limited details available; no large-scale Western RCTs).\n\nPilot studies in healthy subjects noted EEG and attention changes (human, small scale).\n\nNo large human trials confirm BDNF upregulation or cognitive recovery endpoints in non-clinical populations.\n\n## Evidence Gaps\n\nMost data derive from rat models and cell cultures; human data remain preliminary and region-specific (stroke context in Russian literature).\n\n---\n\nRelated:\n[Semax](/a/semax)\n\n[[embed:semax]]","register":"source_ledger","tags":["peptide","topic"],"style":{},"claims":[{"id":"c1","text":"Semax increases BDNF protein levels in rat basal forebrain after intranasal application","section":"mechanism","tier":"preclinical","source_ids":["s1"],"source_status":"sourced","why_material":"Core mechanistic claim separating rat data from human"},{"id":"c2","text":"Semax increases BDNF mRNA and TrkB phosphorylation in rat hippocampus","section":"mechanism","tier":"preclinical","source_ids":["s2"],"source_status":"sourced","why_material":"Direct evidence of upregulation and signaling"},{"id":"c3","text":"Semax raised plasma BDNF in 110 post-stroke patients","section":"mechanism","tier":"speculative","source_ids":["s3"],"source_status":"sourced","why_material":"Only referenced human BDNF data point"},{"id":"c4","text":"Commercial vendors and clinics market this compound (2 commercial/clinic sources catalogued) — marketing material, not evidence.","section":"who_claims_what","tier":"speculative","source_ids":["s71","s92"],"source_status":"sourced","why_material":"Collapsed 6 duplicate marketing claims"},{"id":"c8","text":"Not medical advice.
