MOLECULE PROFILE

Semax

Peptide or peptide-related

Analogue related to an ACTH fragment investigated in neurological contexts. Stroke-rehabilitation information is not demonstrated cognitive enhancement in healthy people.

Sources checked · October 16, 2026

Published for review · Scientific, medical, translation and citation review pending. Reported uses are not authorized indications. Frequency reflects mentions in supplied sources, not sales or global clinical prevalence.

Identity and synonyms

Identity follows the supplied name and synonyms; no additional identity description is supplied.

Synonyms: ACTH(4–7)-PGP analogue

Peptide or peptide-related · Peptide or peptide derivative

Detailed molecular class: Synthetic peptide

Supplied sequence or chemical reference

See identity note; no supplier sequence accepted as verification.

Mechanism

Neurotrophic/BDNF-related hypotheses.

Evidence and critical reading

Reported scientific and empirical uses

Cognition and neurology

Handbooks describe focus, stress and neuroprotection. Post-stroke use, nootropic use and subcutaneous administration need separate evidence records.

Human evidence

Stroke-rehabilitation report is limited and not proof of healthy cognitive enhancement.

Preclinical evidence

Mechanistic and animal effects do not validate cognitive stacks.

Critical reading and limitations

The 110-patient study assessed BDNF and functional recovery in rehabilitation; its abstract does not establish a blinded placebo trial supporting generalization. A reported patient dose is not a basis for calculating a wellness regimen.

Evidence applies to the exact molecule, formulation, route, population and endpoint studied. Supplier identity, purity and clinical equivalence are unverified.

Source-specific regimens

Descriptive source observations, not individual recommendations.

Regulatory product labeling

Listed regimens preserve source/context. An empty layer means no regimen attributable to this identity was verified in this review; it does not prove universal absence of data.

Human-study exposure

Listed regimens preserve source/context. An empty layer means no regimen attributable to this identity was verified in this review; it does not prove universal absence of data.

Empirical handbook

NOT A RECOMMENDATION.Each amount is attributed to the source identified for that entry: regulatory product labeling, human research, or community and practice sources. These source categories have different evidentiary roles. They are not medical advice, not a protocol, not a recommended or safe dose, and not evidence that it works. Do not use them to start, change or stop any treatment. Talk to a qualified healthcare professional.

Regulation and safety

Jurisdiction-specific regulatory context

US/EU authorization not established in reviewed official sources. Claims of Russian authorization require a current national record.

Adverse effects and unknowns

Long-term safety, psychiatric effects and interactions require better characterization. Modified analogues cannot inherit safety.

Contraindications

See supported safety statements and exact product label; a complete contraindication set has not been established for this catalog material.

A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.

Interactions

Only explicitly cited interactions may be asserted; unstudied combinations remain unknown, not interaction-free.

Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.

Studies and trials

Selected studies

PMID29798983 · Clinical rehabilitation study

Rehabilitation after ischemic stroke.

Abstract reports daily amount; route not confirmed here.

BDNF and functional-recovery signals.

Allocation/blinding insufficiently described in abstract; do not extrapolate to healthy people.
