About the compound
What is Semax?
Semax is a synthetic peptide derived from the ACTH(4-10) fragment, developed by researchers in Russia. It has CAS number 80714-61-0 and a molecular weight of 813.94. Structurally it is a short heptapeptide that lacks the hormonal activity associated with the parent ACTH sequence while retaining a fragment of interest to neuroscience research. Within a laboratory catalogue it sits in the nootropic research category and is supplied for research use only.
Semax is examined for its influence on neurotrophic signalling, and a recurring theme in the research literature is its association with BDNF (brain-derived neurotrophic factor) expression. In experimental models it has also been studied in relation to neuropeptide and monoaminergic systems. These mechanistic investigations are conducted in animal and cell-based systems and characterise molecular and biochemical responses rather than outcomes in humans.
Semax is investigated in nootropic and neuroprotection research, where models of cognitive function and neuronal stress are used to characterise its activity. It is frequently discussed alongside Selank, another Russian-developed research peptide, as the two are often examined in comparable experimental frameworks. All such work is confined to laboratory settings and does not constitute evidence of any effect when used by people.
Semax UK stock is provided by Sova as a lyophilised powder intended for controlled laboratory work. Each batch undergoes reverse-phase HPLC and electrospray-ionisation mass spectrometry analysis, with the data captured on a batch-linked Certificate of Analysis. The peptide is sourced and stored in the United Kingdom to support consistent supply for research users. This material is sold strictly for laboratory research use only.

FAQ
Semax, answered.
What is Semax?
+
Semax is a synthetic heptapeptide derived from the ACTH(4-10) fragment and developed in Russia (CAS 80714-61-0, molecular weight 813.94). It lacks the hormonal activity of the parent sequence and is used as a reference peptide in neuroscience-focused research.
Is Semax legal to buy in the UK?
+
In the UK, Semax is supplied as a research chemical for laboratory research use only. It is not an authorised medicine and must not be marketed or used for human purposes. Sold on that basis, it can be purchased by researchers and institutions.
What is Semax studied for?
+
Semax is investigated in nootropic and neuroprotection research, including its association with BDNF expression and neuropeptide signalling. Studies use animal and cell-based models of cognitive function and neuronal stress, and their findings are confined to laboratory settings.
How is Sova's Semax verified?
+
Each batch of Sova's Semax is analysed by reverse-phase HPLC to assess identity and composition and by electrospray-ionisation mass spectrometry to confirm molecular mass. The results accompany the material on a batch-linked Certificate of Analysis.
How should Semax be stored?
+
Semax is best kept as a lyophilised powder in a sealed container away from light and moisture, in cold conditions such as a freezer for longer-term storage. Reconstituted solutions are usually refrigerated and used within a short period.
How is Semax related to Selank?
+
Semax and Selank are both short synthetic peptides developed in Russia and are frequently studied together. Semax derives from an ACTH fragment, while Selank is a tuftsin analogue; researchers often compare the two within similar experimental frameworks.
