META-TITLE: [TODO: Semax — Nootropic Peptide Research Profile | Brand]
META-DESC: [TODO: Semax research overview — ACTH(4-10) analog, BDNF upregulation, neuroprotection, cognitive research.]

[TODO] Hook — Semax as a Russian-developed nootropic peptide, prescribed in Russia/Ukraine since 1990s, BDNF upregulation, unique melanocortin pathway

What is Semax?

[TODO] Full name — Semax, Met-Glu-His-Phe-Pro-Gly-Pro (ACTH 4-10 analog + PGP)
[TODO] Origin — developed at the Institute of Molecular Genetics, Russian Academy of Sciences
[TODO] Classification — synthetic melanocortin derivative, nootropic peptide
[TODO] Approved use — Russia (stroke recovery, cognitive enhancement, optic nerve disease)
[TODO] Administration — intranasal (primary), subcutaneous

Mechanism of Action

[IMAGE: Semax mechanism diagram — BDNF pathway, melanocortin receptors, dopaminergic/serotonergic modulation]

[TODO] BDNF upregulation — increases Brain-Derived Neurotrophic Factor expression
[TODO] Melanocortin system — MC3/MC4 receptor interaction (without ACTH hormonal effects)
[TODO] Dopaminergic — modulates dopamine and serotonin turnover
[TODO] Neuroprotection — anti-oxidative, anti-inflammatory in CNS
[TODO] NGF / TrkB — neurotrophic factor signaling enhancement

Research Highlights

[TODO] Stroke — accelerated cognitive recovery in ischemic stroke patients (Russian trials)
[TODO] Memory — improved attention, memory consolidation in animal and human studies
[TODO] ADHD — Russian pediatric studies showing attention improvement
[TODO] Optic nerve — neuroprotective in optic nerve atrophy (clinical use in Russia)
[TODO] Gene expression — modulates 24 genes related to immune and vascular function

Dosing Protocols (Research Context)

[TODO] Intranasal — 200-600mcg/day (1-2 drops per nostril, 2-3x daily)
[TODO] Subcutaneous — 100-500mcg/day
[TODO] N-Acetyl Semax variant — enhanced stability, higher potency per mcg
[TODO] Duration — 10-14 day cycles, can repeat after washout

Safety & Considerations

[TODO] Excellent safety — decades of clinical use in Russia, no major adverse events
[TODO] No hormonal ACTH effects — does not affect cortisol, adrenal function
[TODO] Mild effects — occasional nasal irritation (intranasal), headache
[TODO] Western data gap — limited peer-reviewed English-language clinical data
