Overview

Semax (ACTH 4–10 analogue) for research use only, is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH). It is widely used in neuroendocrine and neuroscience research due to its involvement in neurotrophic signalling pathways and central nervous system activity models.

This vial contains 5mg of Semax, supplied lyophilised (freeze-dried), research grade, in a sealed vial. Each batch is independently tested and a batch-specific Certificate of Analysis is published on this page before sale.

Semax is investigated in research settings including neuropeptide signalling, synaptic plasticity models, neurotrophic factor regulation, and neuroendocrine system research. Velyx makes no health claims about this compound.
