Semax is a synthetic heptapeptide analogue of the ACTH(4-10) fragment, used in neuroscience research. Supplied as 25 mg in an aqueous research solution in a sealed glass bottle with a pump closure, with a lot-matched Certificate of Analysis.
- Research use only Not for human or veterinary use
- Certificate per lot Published against the lot number
- Independently tested RP-HPLC with LC-MS identity
- Restricted sale 21+ qualified researchers only
Overview
Semax is a synthetic heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro) based on the ACTH(4-10) fragment of adrenocorticotropic hormone, extended with a Pro-Gly-Pro sequence to improve stability. It lacks the hormonal activity of ACTH. This format supplies Semax pre-dissolved in an aqueous research solution.
Research context
Semax is used in preclinical neuroscience research, including studies of neurotrophic factor expression such as BDNF, and models of neuronal stress and cognitive function.

- A lot-specific Certificate of Analysis, available on this page and in the COA library
Identity and chemistry information for laboratory research use only.
On arrival
- Inspect: Check that the seal is intact and that the lot number on the label matches the Certificate of Analysis.
- Store: Move the sealed bottle to 2 to 8 °C as soon as it is received.
- Protect: Keep the bottle upright and away from direct light. Do not freeze.
Solution storage
Semax is supplied as 25 mg in an aqueous research solution, in a sealed glass bottle with a pump closure. Peptides in solution are less stable than lyophilized material, so keep the bottle sealed at 2 to 8 °C, upright and protected from light, until it is needed. Short periods at ambient temperature in transit are tolerated.
After opening
Once the seal is broken, keep the bottle closed and refrigerated between uses, and record the opening date on the label. Use the material within the stability window set by your laboratory’s validated procedures, and do not return unused solution to the bottle.
Disposal
Dispose of unused material and contaminated consumables as laboratory chemical waste, in line with applicable federal, state and local rules.
Laboratory storage and handling information only. No dosing or administration guidance is given or implied.
What purity specification does this lot meet?
Every lot of Semax is tested for identity and purity by HPLC-MS before release. The measured purity for your lot is shown on its Certificate of Analysis, matched to the lot number printed on the bottle label.
Where do I find the Certificate of Analysis for my bottle?
Lot testing records appear on this product page. You can also search by compound name or lot number in the COA library.
What arrives with the order?
One sealed glass bottle with a pump closure per unit ordered, containing 25 mg in an aqueous research solution. Each bottle is labeled with the compound name, quantity and lot number, so it can be matched to its Certificate of Analysis.
How should the bottle be stored when it arrives?
Move the sealed bottle to 2 to 8 °C, upright and protected from light, as soon as it is received. Do not freeze. The Storage and handling tab covers storage, opening and disposal.
Is Semax for human or veterinary use?
