Semax is a synthetic heptapeptide analog of the adrenocorticotropic hormone (ACTH) fragment ACTH(4-7), developed at the Institute of Molecular Genetics in Moscow. It has been studied in neuroscience research for its apparent neurotrophin-like activity — particularly its interaction with BDNF (brain-derived neurotrophic factor) and TrkB receptor signaling, pathways that are central to neuronal survival and synaptic plasticity research.
Research has explored Semax in models of neuroprotection and cognitive signaling, investigating how ACTH-derived peptides interact with central nervous system biochemistry. Studies have examined its influence on dopaminergic and serotonergic neurotransmission, as well as its potential role in modulating the HPA (hypothalamic-pituitary-adrenal) axis response in pre-clinical models.
Semax has also been investigated in models examining cerebrovascular biology and neuroinflammation, where BDNF-related signaling plays a documented role in neuronal recovery pathways. Its ACTH analog structure makes it a useful research tool for labs studying neuropeptide pharmacology and central nervous system peptide signaling.
myPEPT supplies Semax at ≥99% verified purity with a Certificate of Analysis from independent lab testing. Lyophilized and shipped across the EU in research-grade packaging.
What researchers should know: Semax is a research peptide for laboratory use only. It is not approved as a therapeutic or nootropic supplement for human use in most jurisdictions. Always handle in accordance with your institution's neuroscience compound protocols and applicable local regulations.

Frequently asked
7 questionsHow fast is delivery and which carriers do you use?
Orders placed before 16:00 CET ship the same business day from the Netherlands via DPD or PostNL. EU-wide delivery typically takes 2–5 working days, fully tracked. Every parcel ships in plain, unbranded packaging with no peptide-related markings visible.
Which payment methods do you accept?
We accept iDEAL (Netherlands), Bancontact (Belgium), PayPal, Klarna pay-later, SEPA instant bank transfer, and Visa/Mastercard credit and debit cards. All payments are processed through PCI-DSS-compliant European processors. Bank transfer and card orders ship within 24 hours of payment confirmation.
How do you verify peptide purity?
Every batch is HPLC-tested to 99% purity or higher by an independent third-party laboratory, with identity confirmed by mass spectrometry. The batch-specific Certificate of Analysis is published on every product page and delivered with the order.
Are research peptides legal to buy in the Netherlands and EU?
Yes — when sold and purchased strictly for in-vitro laboratory research. Research peptides on my\PEPT.eu are not approved, marketed or intended for human or veterinary use, medical diagnosis or therapeutic application. By placing an order you confirm research-only intent and accept responsibility for compliance with local regulations.
How should research peptides be stored?
Lyophilized (freeze-dried) peptides keep up to 24 months at −20 °C in a sealed vial. Once reconstituted in bacteriostatic water, store at 2–8 °C and use within 28 days. Avoid repeated freeze-thaw cycles and direct sunlight.
What is Semax as a research peptide?
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) derived from the adrenocorticotropic hormone (ACTH) sequence, with a molecular weight of approximately 813 Da. It is studied in laboratory research for its receptor-binding profile. Semax is sold strictly for in-vitro research use only and has not been approved by the EMA, FDA, or any national medicines authority.
How should Semax be stored?
Lyophilized Semax should be stored at −20 °C in a sealed, light-protected vial. After reconstitution in bacteriostatic water or sterile saline for laboratory assay use, store at 2–8 °C and use within 28 days. Do not refreeze reconstituted solution. Research-use only — not for human use.
