Cognitive Peptide Research: SEMAX and Selank

Compound Research

This page summarises findings from published academic literature. It does not describe or endorse use in humans or animals.

SEMAX and Selank are two synthetic peptides frequently referenced together in cognitive and neurological research literature, both originating from Russian pharmacological research. This page gives a general overview of what published research examines for each, and how the two compounds differ.

What Is SEMAX?

SEMAX is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH). It has been studied in research contexts relating to neurotrophic factor expression and neurological signalling pathways, most commonly in rodent models and cell-based studies.

What Is Selank?

Selank is a synthetic heptapeptide analogue of tuftsin, a naturally occurring immunomodulatory peptide. Published research on Selank has examined anxiolytic-adjacent behavioural models and immune-modulatory pathways, again primarily within animal and cell-based research settings.

How Published Research Approaches Both Compounds

Although SEMAX and Selank originate from different parent molecules, research literature on both peptides overlaps in several areas, including studies on brain-derived neurotrophic factor (BDNF) expression, stress-response models, and rodent behavioural assays. Despite these overlapping research themes, the two compounds have distinct structures and are studied as separate research subjects rather than interchangeable ones.

Frequently asked questions

Are SEMAX and Selank the same compound?

No. They are structurally distinct peptides derived from different parent molecules. They are often discussed together because their research literature overlaps in some areas, but they are separate research subjects.

Are SEMAX and Selank tested before dispatch?

Yes. Every batch is independently tested and issued with a batch-specific Certificate of Analysis before dispatch.

Are these compounds intended for human or animal use?

No. All compounds discussed on this site are supplied strictly for in vitro laboratory research use only, and are not intended for human or animal administration.

Where can I find the Certificate of Analysis for these compounds?

Batch-specific Certificates of Analysis are published in the PerformanceLabsUK COA library, referenced against the batch number shown on the product page.
