Semax is a synthetic heptapeptide analogue derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4-7), extended with the Pro-Gly-Pro sequence. It was developed in Russia and has been the subject of ongoing preclinical research in neurobiological modeling and neurotrophic factor signaling. Heartland Bio Labs supplies Semax as a lyophilized research compound of verified purity.

Semax has been investigated in preclinical and clinical research exploring BDNF (Brain-Derived Neurotrophic Factor) modulation, neurobiological signaling, and neuroinflammatory response in rodent models. Published research has examined its interaction with neurotrophin signaling pathways and its neuroactive properties in ischemic brain tissue models. Semax has an established published research literature spanning several decades.

This compound is supplied strictly for research purposes. No clinical or therapeutic application is implied or represented.

How should I store this peptide?+

Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.

What should I reconstitute it with?+

Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.

How quickly do orders ship?+

Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.

Is the COA verified independently?+

Yes. Every lot is tested by HPLC for purity (target ≥99%) and mass spectrometry for molecular identity before release. The COA is generated from the actual lot data, not a generic template.

Can I get bulk or institutional pricing?+

Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
