Description
Semax (SMX), 10mg
SMX is a synthetic peptide derived from a fragment of adrenocorticotropic hormone (ACTH 4–10), modified to enhance stability in research environments. Its sequence is Met-Glu-His-Phe-Pro-Gly-Pro: the ACTH-derived Met-Glu-His-Phe, followed by a Pro-Gly-Pro extension. In the published literature it has been studied in laboratory models of neurotrophic factor and neurotransmitter signaling.
This 10mg vial from Fit Aminos is manufactured to research-grade standards and intended strictly for scientific and laboratory use.
