What is Semax?

ACTH(4-10)-derived heptapeptide studied in neuroplasticity research.

Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment, developed as a research tool in neuropeptide science. It is studied in the context of brain-derived neurotrophic factor (BDNF) expression, neuroplasticity and neuroprotection in cellular and preclinical models. Researchers investigate Semax for its influence on dopaminergic and serotonergic signalling, attention and memory-related pathways, and the response of neurons to oxidative and ischaemic stress. Its rapid activity and well-characterised sequence make it a frequent reference compound in cognitive research. Third-party tested to 99%+ purity and supplied as a lyophilized powder for laboratory reconstitution. For research purposes only, not for human consumption.

How is Semax stored and handled?

Storage

Store lyophilized vials at -20°C, protected from light. Once reconstituted, refrigerate at 2-8°C and use within the recommended window.

Reconstitution

Use bacteriostatic water; add slowly down the inside wall of the vial. Swirl to dissolve, never shake. See the in-house peptide calculator for concentration (mg/ml) and syringe units (IU on a U-100 syringe).

Before you order

Every peptide batch is tested by Janoshik Analytical, an independent third-party lab. The batch number, test date and measured purity are shown on the product page, and the full report is available in the lab results section.

We ship from inside the European Union, so parcels stay within the single market and are not subject to import clearance. We have not had customs problems on EU shipments, and if a parcel is ever stopped it is covered by our Vital Guarantees reship.

It is covered by Vital Guarantees. If your parcel is not delivered within 10 working days, or is lost or stopped in transit, we reship it once, free, no questions asked.

Yes. Our compounds are freeze-dried (lyophilised), which makes them stable at ambient temperature for the duration of transit. Refrigerate on arrival, and store reconstituted material at 2-8°C.
