Semax

Description

Semax is a synthetic peptide developed from a fragment of adrenocorticotropic hormone and has been the subject of neuroscience research for more than three decades. Limitless Life Nootropics supplies it as a 30mg lyophilized powder, made in the USA and independently tested.

What Is Semax?

The compound was designed at the Institute of Molecular Genetics of the Russian Academy of Sciences in the 1980s. Researchers took the ACTH(4-7) fragment (Met-Glu-His-Phe) and extended it with a Pro-Gly-Pro tail, producing the heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro. The added proline-rich tail greatly improved resistance to enzymatic breakdown while removing the hormonal activity of the parent ACTH molecule.

In preclinical models, investigators have studied how the peptide influences brain-derived neurotrophic factor (BDNF) and its receptor TrkB, along with dopaminergic and serotonergic signaling. It has also been examined in experimental models of ischemic stroke and in studies of attention and memory in rodents.

This is the original, unmodified form of the molecule. Researchers interested in the N-acetylated or amidated versions can find those in our cognitive research category.

Areas of Scientific Investigation

Laboratory studies have explored this peptide across several areas of investigation:

• BDNF and TrkB expression in the hippocampus
• Experimental cerebral ischemia models
• Dopamine and serotonin turnover studies
• Learning, attention and memory paradigms in rodents
• Gene expression profiling in neural tissue

Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.

Frequently Asked Questions

What is the sequence of this peptide?

It is the heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, built from the ACTH(4-7) fragment plus a stabilizing Pro-Gly-Pro tail.

How is it different from N-Acetyl Semax?

The N-acetyl version adds an acetyl group to the N-terminus, which is intended to further increase resistance to enzymatic degradation.

Is this peptide for human use?

No. It is sold strictly for laboratory research. It is not intended for human or animal consumption, diagnosis or treatment.

Where can I buy Semax online?

You can order it directly from Limitless Life Nootropics, a U.S. supplier of third-party tested research peptides with fast, discreet shipping.
