Semax is a synthetic heptapeptide analogue of the ACTH(4-10) fragment, proline-modified for enzymatic stability, and a landmark of Russian neuropeptide research studied in neuroprotection, BDNF-signalling and cognition models. CAS 80714-61-0; molecular formula C39H54N10O10S; sequence Met-Glu-His-Phe-Pro-Gly-Pro; supplied lyophilised at ≥99% by HPLC. For laboratory research use only.
Developed from a fragment of a naturally occurring hormone, Semax is a synthetic heptapeptide analogue of the ACTH(4-10) sequence, stabilised by a C-terminal Pro-Gly-Pro extension that resists rapid enzymatic breakdown. It is one of the most studied peptides in the neuropeptide and neuroprotection literature, particularly within Russian and broader experimental research on cognition and brain injury.
A stabilised fragment of ACTH. Semax was engineered by modifying the N-terminal region of the melanocortin ACTH(4-10) fragment and adding a proline-containing tail, a design that confers metabolic stability while retaining centrally active, non-hormonal properties (Glazova et al., 2005). This structural strategy underpins the peptide's enduring use as a research tool for probing melanocortin- and neurotrophin-related signalling.
What the research explores. Across animal and in-vitro systems, Semax has been investigated along several intersecting themes:
The activity described here is drawn from in-vitro and animal studies; it characterises biological behaviour in experimental models and does not establish efficacy or safety in humans. Full citations are listed under the Scientific References tab.

Semax is a synthetic heptapeptide analogue of the ACTH(4-10) sequence, supplied strictly as a research-use-only reference material. Its sequence (Met-Glu-His-Phe-Pro-Gly-Pro) carries a C-terminal Pro-Gly-Pro extension that resists rapid enzymatic breakdown. Condor Research offers it as a 10 mg lyophilized vial at ≥99% HPLC purity for in-vitro laboratory study only.
Semax and Selank are different synthetic heptapeptides from distinct origins. Semax (Met-Glu-His-Phe-Pro-Gly-Pro) derives from the ACTH(4-10) fragment and is studied as a neuropeptide/nootropic research model. Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) derives from the immune peptide tuftsin and is investigated in anxiolytic-focused research. Both are sold as separate ≥99% HPLC, research-use-only reference compounds.
That depends on your experimental design. Separate 10 mg vials of Semax and Selank let you control each compound's concentration independently, while the co-formulated Semax + Selank blend (10 mg + 10 mg) supplies both peptides in one vial. All formats are research-use-only reference materials. For pricing comparison, contact info@condorresearch.com.
Semax is engineered from the ACTH(4-10) fragment of adrenocorticotropic hormone, stabilized by a Pro-Gly-Pro tail; Selank is engineered from tuftsin, an immune-derived tetrapeptide. The two share a heptapeptide length but originate from unrelated parent molecules, which is why they are studied as distinct neuropeptide research tools rather than interchangeable analogues.
Semax is a single, chemically defined synthetic heptapeptide (≥99% HPLC), whereas Cerebrolysin is a defined biological peptide mixture rather than one molecule. Researchers select Semax when a single, sequence-verified reference compound is needed, and Cerebrolysin when a complex peptide preparation is the study subject. Both are supplied as research-use-only materials.
Yes. Semax is supplied strictly for laboratory research use only (in vitro). It is not a medicine, food, supplement, cosmetic, or medical device, and is not for human or veterinary use, administration, or consumption. Condor Research provides no human-use guidance, dosing, or protocols. Purchase is limited to qualified professionals and institutions aged 18 or over.
For analytical laboratory preparation only, Semax is water-soluble and can be reconstituted with a sterile aqueous diluent; the chosen volume sets the working concentration. Store the sealed lyophilized vial at -20°C, protected from light, with a 24-month shelf life from manufacture. This is laboratory handling information, not guidance for any human or animal use.
Yes. Each Semax lot is tested by an independent third-party laboratory by HPLC for identity and purity, with mass spectrometry confirmation, and ships against a batch-specific Certificate of Analysis (COA) verifying ≥99% purity. To request the COA for the current lot before ordering, contact info@condorresearch.com.
Each Semax vial contains 10 mg of lyophilized peptide at ≥99% HPLC purity, supplied as a research-use-only reference material. The stated mass is an analytical reference quantity, not a dose. Vial fill and identity are verified by independent third-party testing and documented on the lot's Certificate of Analysis.
Stability of a reconstituted Semax solution depends on the diluent, temperature, and sterility of your laboratory preparation, so an exact window cannot be guaranteed for every setup. As a reference reagent, the sealed lyophilized vial is most stable stored at -20°C, protected from light. Treat any prepared solution as you would a sensitive research peptide.
Cold-chain handling was respected end to end. Vials arrived sealed, labelled and intact. Documentation is the most thorough I've seen from an EU supplier.
Solubility and stability were as described. Knocked one star only because express shipping options are limited, but quality is not in question.
Third order with Condor. Batch-to-batch variation is minimal, which matters for our longitudinal work. The mono-labelled vials are easy to track.
No marketing fluff — just characterised material with paperwork. The data sheet and CAS matched our records precisely.
