Research Handling Guidance

Before reconstitution, allow both the lyophilised peptide and your chosen diluent to settle at normal laboratory room temperature. Equalising temperatures in this way supports the structural stability of the compound while it goes into solution.

Diluents and reconstitution solutions are purchased separately.

£25.30/ 5mg vial

Dosage

Synthetic ACTH(4-7) analogue heptapeptide

Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) based on the ACTH(4-7) fragment with the same Pro-Gly-Pro extension used in Selank. It has no corticotropic activity and is studied as a neuropeptide affecting BDNF expression and related pathways in published work.

Supplied as a lyophilised powder in two strengths, manufactured in the UK and independently tested for purity and identity.

Research applications include neurotrophin expression models, cerebral ischaemia studies in animal systems and melanocortin-pathway work. Laboratory research use only.

Semax questions

How is Semax tested?

Each production batch is sent for independent HPLC purity analysis and mass spectrometry identity confirmation by Janoshik Analytical. The batch reference printed on the vial links to its Certificate of Analysis, which can be viewed on the lab's own verification site.

How is Semax supplied?

As a sterile lyophilised (freeze-dried) powder in a sealed glass vial, available in two vial strengths. Vials are labelled with compound name, strength and batch reference and are dispatched in plain, tracked packaging from the UK.

How should the lyophilised vial be stored?

Unopened lyophilised vials should be kept refrigerated at 2–8 °C, or at −20 °C for long-term storage, protected from light. Once reconstituted, solutions should be refrigerated and used within the period appropriate to the laboratory's own stability data.

Is this for human use?

No. All Regent Peptides products are supplied strictly for in-vitro laboratory research. They are not medicines and are not for human or veterinary use, diagnosis or treatment.
