Selank is a synthetic anxiolytic peptide developed from Tuftsin and studied in Russian clinical settings for its interaction with stress, anxiety, and immune pathways. Here is what the evidence shows and what legal access looks like in Australia.

Selank is a synthetic heptapeptide, meaning it is composed of seven amino acids, developed from Tuftsin, a naturally occurring tetrapeptide produced by the spleen that plays a role in immune function. The modification of Tuftsin into Selank was carried out to create a compound with anxiolytic and nootropic properties while retaining some of the immune-related activity of the parent molecule.
Selank was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It has been studied in Russian clinical settings and carries a more developed clinical research history than many compounds discussed in the Australian peptide space. This research history includes investigation of its effects on anxiety, stress responses, cognitive function under stress, and immune modulation.
Like several other compounds with Russian research origins, Selank's evidence base is concentrated in Russian-language literature. This does not invalidate the research but does make it less accessible to reviewers working primarily with English-language sources.
Research into Selank has primarily examined its interaction with the GABAergic system, which is the primary inhibitory signalling system in the central nervous system and the same system through which many conventional anxiolytic medications work. Research has compared Selank's anxiolytic profile to that of benzodiazepines, with interest in whether it can produce anxiolytic effects through a different mechanism with a different side effect profile.
Immune-modulating properties have also been examined, particularly Selank's interaction with interleukin signalling pathways. This dual profile, interaction with both central nervous system stress pathways and immune signalling, reflects its structural relationship to Tuftsin and has been a focus of research examining whether stress and immune function effects can be addressed simultaneously.
Cognitive function under stress conditions has also been studied. Research has examined whether Selank can maintain or improve cognitive performance in high-stress contexts, which is a distinct question from simple anxiolysis.
Selank is available as a nasal spray: Selank is available through licensed Australian compounding pharmacies in nasal spray form, which is an alternative administration route to injectable peptides. The nasal mucosa provides a pathway for peptide absorption that bypasses some of the degradation that would occur through oral administration. The specific formulation appropriate for any individual is determined by the prescribing doctor.
Selank is a Schedule 4 prescription-only medicine in Australia. It is accessible through UHD BioHealth's standard assessment and prescription pathway when a prescribing doctor determines it is clinically appropriate following a full assessment of the individual's health history, current medications, and goals.
