Semax is a synthetic heptapeptide analogue of the ACTH(4–7) fragment of adrenocorticotropic hormone, first developed at the Institute of Molecular Genetics in Moscow, and it has become a well-characterised subject in neuroscience research. Investigations have centred on its apparent neurotrophin-like behaviour — in particular its reported interaction with BDNF and TrkB receptor signalling, pathways studied in the context of neuronal survival and synaptic plasticity — as well as its influence on dopaminergic and serotonergic neurotransmission and on hypothalamic-pituitary-adrenal axis responses in pre-clinical models. Its ACTH-derived structure, paired with the absence of adrenocorticotropic activity, makes it a useful reference tool for laboratories studying neuropeptide pharmacology, cerebrovascular biology, and central-nervous-system peptide signalling. myPEPT supplies Semax at ≥99% verified purity with a batch Certificate of Analysis from independent lab testing, lyophilized and shipped across the EU in research-grade packaging. It is a research peptide for laboratory use only: it is not approved as a therapeutic or nootropic product for human use in most jurisdictions, is not for human consumption or injection, and should always be handled 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.
