What customers say
Research overview
Semax is a synthetic heptapeptide analogue of the ACTH(4-10) fragment of adrenocorticotropic hormone, sometimes written Semax peptide. Developed at the Institute of Molecular Genetics in Moscow and supplied here as a UK-manufactured liquid peptide solution for researchers looking to buy Semax in the UK, it has been the subject of extensive neurological research, particularly in the areas of neuroprotection and cognitive function.
BDNF and NGF Expression
One of the most studied aspects of Semax is its influence on neurotrophic factor expression. Research has examined its effects on brain-derived neurotrophic factor (BDNF) upregulation in hippocampal and cortical tissue, nerve growth factor (NGF) expression in preclinical models, and the downstream effects of neurotrophic signalling on neuronal survival and plasticity.
Neuroprotection Research
Semax has attracted interest in neuroprotective research contexts. Studies have investigated its protective effects in models of oxidative stress-induced neural damage, interactions with anti-apoptotic signalling cascades in neural tissue, and its effects on microglial activation and neuroinflammatory mediators.
Ischaemic Recovery Models
A significant body of preclinical research has examined Semax in cerebral ischaemia models. Research has explored its effects on infarct volume following experimental ischaemic events, neurovascular unit preservation in stroke models, and recovery of neurological function in preclinical settings.
Dopaminergic and Serotonergic Research
Semax has also been studied in relation to monoamine neurotransmitter systems, including dopamine receptor sensitivity modulation and serotonin turnover in brain regions associated with mood and cognition.

Frequently asked questions
Is a Certificate of Analysis included?+
Yes. Every order ships with a third-party CoA matched to the lot number printed on your cartridge. A sample CoA is available on the site.
How is purity verified?+
Each batch is HPLC-tested for purity and mass-spec confirmed for identity, then tested for heavy metals, residual solvents and endotoxins.
Does the solution need reconstituting?+
No. The cartridge is supplied as a ready-to-use liquid solution in 3ml bacteriostatic water.
How is it shipped and stored?+
Validated temperature-controlled packaging, UK next-day dispatch. Store at 2–8°C on arrival, do not freeze, 12-month shelf life.
Who is this supplied to?+
Qualified personnel for in vitro laboratory research and analytical work only. Not for human or animal consumption.
