RESEARCH OVERVIEW
What is Semax?
Semax (Met-Glu-His-Phe-Pro-Gly-Pro) combines the ACTH (4-7) fragment with a C-terminal Pro-Gly-Pro tripeptide that slows enzymatic breakdown. It has no hormonal activity at adrenal receptors.
Research has focused on neurotrophic signalling, including BDNF expression, and on gene expression changes in models of cerebral ischaemia.

Semax vs Selank
Selank is a tuftsin analogue from the same research institute. The two are often studied together in functional connectomics work.

Purity and testing
Certificates of analysis are published on our Lab Reports page as each batch is released.
No certificate is published for this product yet. Certificates appear on our Lab Reports page as each launch batch is released, and this page updates the moment a result is issued. We do not display a purity figure until we hold the certificate behind it.
Laboratory handling
Reconstitution
- Allow the sealed vial to reach room temperature.
- Wipe the stopper with an alcohol swab.
- Add diluent slowly down the inside wall of the vial.
- Swirl gently until dissolved. Do not shake.
- Label with concentration and date, then refrigerate.
Storage
- Lyophilised: -20°C for long-term storage, sealed and dry, away from light.
- Short term: 2 to 8°C for weeks in the sealed vial.
- Reconstituted: 2 to 8°C, protected from light. Avoid repeated freeze-thaw cycles.
Semax FAQs
Is Semax for human use?+
No. Semax is sold strictly for laboratory research use only. It is not a medicine, food supplement or cosmetic and must not be used in humans or animals.
How is Semax tested?+
No certificate has been issued yet, so no purity or identity result is claimed for any batch. Certificates are published on our Lab Reports page as each batch is released.
How should Semax be stored?+
Lyophilised material should be stored sealed, dry and protected from light, ideally at -20°C for long-term storage. After reconstitution, laboratories typically store solutions at 2 to 8°C and avoid repeated freeze-thaw cycles.
How quickly will my Semax order arrive?+
Enquiries are currently closed. No order or delivery is scheduled from this site. See our shipping policy for indicative delivery information.
Which Semax strengths are available?+
Semax is available in 10mg (£24.99), 5mg (£19.99). Larger vials cost less per mg.
Do I need bacteriostatic water for Semax?+
Lyophilised peptides are supplied as dry powder. Laboratories reconstitute them with a suitable diluent such as bacteriostatic water, which we stock separately. Our reconstitution calculator works out the resulting concentration.
