Description
Semax: Research Compound Overview
Semax is a research compound supplied by Stimulus Labs for laboratory and in-vitro use. It is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro), an analog of the ACTH(4–10) fragment extended with a C-terminal Pro-Gly-Pro sequence for stability and lacking hormonal ACTH activity. It is studied in neuroscience research for interactions with neurotrophic signaling, including BDNF, with proposed neuroprotective effects in preclinical models. Molecular formula C37H51N9O10S; molecular weight approximately 813.9 g/mol. Supplied as a lyophilized powder.
It is offered at 99%+ purity, with every batch independently verified by third-party HPLC and mass-spectrometry testing before listing, so researchers can trust the identity and purity of the material they receive. Stimulus Labs works only with laboratories that document their methodology, and re-tests new supplier lots before they reach the catalog, rather than relying on a single certificate provided at the point of manufacture.
Purity, Testing & Handling
Every batch ships with a batch-specific Certificate of Analysis (COA), confirming identity and purity ahead of listing, and available to view before you buy. Researchers should store the lyophilized powder at the temperature indicated on the vial label, reconstitute only with an appropriate diluent such as bacteriostatic water, and handle it exclusively within a controlled laboratory setting using standard aseptic technique. Once reconstituted, solutions are generally less stable than the lyophilized form, so researchers typically prepare only the volume needed for near-term use and record storage conditions as part of their protocol.

Chemical Identity
Semax is associated with CAS number 80714-61-0. Researchers can cross-reference this number against the CAS Common Chemistry registry to independently confirm identity rather than relying on any single supplier’s labeling. Keeping a record of lot numbers, COA results, and CAS verification alongside any published research is good practice for maintaining a reproducible research record.
For Research Use Only. Not for human or veterinary use. Not a drug, food, or cosmetic. Semax is sold exclusively to qualified researchers and institutions for laboratory research purposes, and Stimulus Labs makes no claims about outcomes outside of a controlled research setting.
