Cognitive / NeuroSynthetic heptapeptide (ACTH 4-7 analog)
Semax
$49.99
10 mg· 2 strengths availableSemax is a synthetic heptapeptide based on the ACTH (4–10) fragment with a C-terminal Pro-Gly-Pro extension that improves enzymatic stability.
Notably, the fragment lacks the corticotropic activity of full-length ACTH, which is what makes it useful: researchers can study peptide effects on neurotrophic signaling — including reported changes in BDNF expression — without confounding adrenal-axis activation.

What you should know

Analytical values reflect per-lot documentation and appear once a batch is released.
Compound
Semax comes out of the Russian neuropeptide literature, where ACTH fragments were investigated for central nervous system activity separable from endocrine effects. Published preclinical work reports changes in brain-derived neurotrophic factor and related trophic-factor expression in rodent models and neuronal cultures. Laboratory applications include gene-expression studies in neuronal cell lines, neuroprotection models, and comparative work across ACTH-derived peptides. Independent replication outside the originating literature is limited, so results are best treated as exploratory.

Synthetic heptapeptide (ACTH 4-7 analog)
Mechanism (research context)
Semax has been characterized in preclinical cognitive-model and BDNF-associated research systems as a defined-sequence reference neuropeptide.
Why it is studied
Semax is one of the most cited ACTH-fragment-derived research peptides in the neuropeptide literature.

Topics reflect published preclinical and in vitro research. Reference only — not a claim of clinical outcomes.
Scientific background
Semax was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences as a stabilized synthetic analog of ACTH 4-7.
It has since been characterized in preclinical cognitive-model literature over multiple decades.
