About Semax
Semax is a synthetic peptide analog of ACTH (adrenocorticotropic hormone) developed in Russia for stroke treatment and cognitive enhancement. It powerfully increases BDNF (brain-derived neurotrophic factor) — the key protein for learning, memory, and neuroplasticity. Unlike ACTH, Semax does not affect cortisol or the adrenal glands. It's approved in Russia for stroke, cognitive disorders, and peptic ulcers.
Who Should Consider Semax
- Individuals seeking cognitive enhancement and improved focus
- Stroke recovery patients (approved indication in Russia)
- Adults with age-related cognitive decline
- Students or professionals needing sustained mental performance
- Patients with dyscirculatory encephalopathy or optic nerve atrophy (Russian indications)
What to Expect
Subtle improvements in mental clarity and focus. BDNF upregulation begins within hours of first dose. Some users notice improved attention span on day one.
More consistent cognitive effects. Enhanced verbal fluency and working memory become apparent. Serotonin and dopamine modulation stabilizes.
Peak cognitive benefits. Noticeable improvements in learning speed, memory retention, and mental stamina. BDNF and TrkB receptor upregulation well-established.
Full therapeutic window. Neuroprotective effects accumulate. Many users report sustained focus and reduced mental fatigue throughout the day.
Cognitive benefits often persist for weeks after stopping due to lasting BDNF elevation and neuroplasticity changes. Typical rest period is 1-2 weeks before next cycle.
Dosing Protocol
| Level | Dose / Injection | Frequency |
|---|---|---|
| Beginner | 200mcg | Daily |
| Moderate | 500mcg | Daily |
| Aggressive | 1mg | Daily |
Note: ACTH analog nootropic. Increases BDNF. Approved as a prescription drug in Russia and Ukraine for stroke, cognitive disorders, and peptic ulcers — not FDA-approved in the US. Nasal or subcutaneous. Cycle 10-20 days.
Pharmacokinetics
Source: Plasma t½ ~2-3 min (IV); functional duration 20-24h due to BDNF cascade (Dolotov et al. 2006, PMID 16996037)

Side Effects
Very well-tolerated. No significant side effects reported in clinical use. Hair thinning at very high doses (rare and reversible).
Contraindications
- Pregnancy or breastfeeding — no safety data available
- Known hypersensitivity to ACTH-derived peptides
- Active intracranial hypertension
- History of seizure disorders (use with caution — limited data)
- Children under 18 without physician supervision
Drug Interactions
- Melanocortin receptor agonists — potential additive effects through shared receptor pathways
- SSRIs and SNRIs — Semax modulates serotonin systems; monitor for serotonergic effects when combined
- Dopaminergic drugs (L-DOPA, dopamine agonists) — Semax increases dopamine turnover; dose adjustment may be needed
- Anticoagulants — limited data; no known interaction but caution advised as Semax has immunomodulatory effects
- Other nootropic peptides (Selank, Noopept) — commonly stacked but start with one compound to assess individual response
