Semax
Heptapeptide analog of ACTH(4-10) studied in Russia for cognitive and neuroprotective effects after stroke.
Educational only — not medical advice. SmartPeptide does not prescribe, diagnose, or treat. Always consult a licensed healthcare provider before using any peptide, supplement, medication, or protocol.
What the research shows
Russian post-stroke and cognitive-performance studies; some BDNF/neurotrophic mechanism work.
What's still experimental
Limited western replication. Cognitive-enhancement claims in healthy adults need larger trials.
Anecdotal / community reports
Focus and clarity reports are common; outcomes depend on dose, formulation, and individual factors.
Anecdotal reports are NOT scientific evidence. They reflect personal experience and may not generalize.
FDA approval status
Source: openFDA + DailyMed (NIH/NLM)Doses studied in research
Source: Published clinical trialWhat published trials tested or FDA-approved labels specify. Reporting research facts — not a SmartPeptide recommendation.
The doses below are aggregated from research-peptide community forums (Reddit, biohacker discussions). They are NOT supported by clinical trials, NOT FDA-approved, and NOT a SmartPeptide recommendation. Source purity, dose accuracy, and user-reported outcomes are unverifiable. We display this only because the information is publicly available elsewhere — visitors should absolutely consult a licensed clinician familiar with experimental peptides before any use.
Notes from the source: Approved in Russia for stroke recovery; not approved or studied at scale in Western RCTs.
How clinicians typically protocol this
Third-party reference · not our recommendationDosing phases, cycle lengths, and administration timing as listed in a compounding-pharmacy clinician reference guide. Shown so you can see what a real protocol looks like — and bring informed questions to a licensed clinician.
Dose numbers, frequencies, and cycle lengths in this panel are extracted from a clinician-facing reference protocol distributed by a US-based compounding pharmacy in November 2025. SmartPeptide has paraphrased all descriptive text and adds no endorsement. Always consult a licensed clinician.
Synthetic ACTH(4-10) analog studied for cognitive, mood, and neuroprotective effects.
Protocol phases
Intranasal onset within 30–60 min.
Protocol notes: Reference reports common stacking with Selank (calm + focus) or with NAD+/MOTS-c for mitochondrial energy.

Funder diversity is a credibility signal. Research concentrated in a single drug company's funding warrants more scrutiny than research funded across NIH, charities, and academic grants.

Questions for your clinician
- Is there independent (non-Russian) replication?
- What baseline cognitive testing would we do to track effect?
