Selank (10mg): Tuftsin-Derived Heptapeptide for Anxiety and Stress Research
Selank is a seven-amino-acid peptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, built from tuftsin, a natural immune-modulating tetrapeptide, with the same Pro-Gly-Pro tail that stabilises Semax. Developed at the Institute of Molecular Genetics in Moscow, it is the calming counterpart to Semax: where Semax research is about attention and BDNF, Selank research is about anxiety, GABA modulation and the stress response, without sedation or dependence in the animal models.

Pure Peptides Australia holds Selank in Sydney stock as a 10mg lyophilised vial, Janoshik tested before listing. Orders confirmed before 12pm AEST on a business day are dispatched the same day with tracked delivery Australia-wide.

Selank vs Semax
Same laboratory, same Pro-Gly-Pro stabilising tail, opposite research profiles. Semax is ACTH-derived and studied for cognition, attention and neuroprotection. Selank is tuftsin-derived and studied for anxiety, stress hormone response and GABAergic tone. Research designs that run both do so to contrast the stimulating and calming arms of the same peptide family.
Key research areas
Anxiolytic activity
Reduced anxiety-like behaviour in rodent elevated-plus-maze and open-field models, comparable to benzodiazepine reference compounds without sedation (Kozlovskii and Danchev, Neuroscience and Behavioral Physiology 2003).
GABA modulation
Reported to alter GABA-A receptor subunit expression and to potentiate GABA signalling, the proposed basis of its calming effect.
Enkephalin protection
Inhibits enkephalin-degrading enzymes, raising endogenous enkephalin levels involved in stress buffering.
Immune modulation
Inherited from tuftsin: studied for interleukin-6 and T-helper balance, tying stress and immune endpoints together.
Memory and learning
Studied for memory consolidation under stress, where anxiety would otherwise impair recall.
BDNF
Reported to increase BDNF in hippocampus, though less prominently than Semax.
How Selank works
Selank has no single receptor. Its tuftsin core interacts with immune and neural signalling, its effect on GABA-A receptor expression shifts inhibitory tone, and its blockade of enkephalinases raises endogenous opioid peptides that damp the stress response. Together these produce the anxiolytic profile seen in animal models without the sedation, muscle relaxation or tolerance associated with benzodiazepines. Half-life is short, which is why intranasal delivery dominates the research literature, as with Semax.

Pricing in Australia
$79.99 for 10mg, $8.00 per mg
Selank is studied in microgram amounts, often several times a day in short courses, so a 10mg vial covers a full course with room to spare. Pair with Semax ($79.99) for the contrast arm.
Reconstitution
Wipe the stopper, add bacteriostatic water slowly down the inside wall, swirl gently until clear, never shake. Refrigerate at 2 to 8ยฐC and use within 28 days.

Selank Australia FAQ
What is Selank?
A seven-amino-acid peptide derived from tuftsin with a Pro-Gly-Pro tail, developed in Moscow. It is studied for anxiety, stress response and GABA modulation in animal models, without sedation or dependence.
Selank vs Semax: what is the difference?
Selank is tuftsin-derived and calming, studied for anxiety and stress. Semax is ACTH-derived and stimulating, studied for attention and BDNF. They are used together for contrast rather than as substitutes.
How does Selank work?
It shifts GABA-A receptor expression toward inhibitory tone, blocks enkephalin-degrading enzymes to raise endogenous opioid peptides, and carries tuftsin's immune-modulating activity. No single receptor.
What does the research show?
Reduced anxiety-like behaviour in rodent models comparable to benzodiazepine references without sedation, altered GABA-A subunit expression, and preserved memory under stress. Most human data come from Russian clinical use.
Can I buy Selank at Chemist Warehouse in Australia?
No. Selank is not a registered medicine in Australia and is not stocked by any pharmacy. It is available only as a research-grade lyophilised vial.
How do you reconstitute Selank?
Add bacteriostatic water slowly down the inside wall, swirl gently until clear, never shake, refrigerate at 2 to 8ยฐC and use within 28 days. 2mL gives 5mg/mL, so 10 units carries 500mcg.
Is Selank available in Australia?
As a research compound, yes: Pure Peptides Australia holds the 10mg vial in Sydney with same-day dispatch. As a medicine, no. As of October 2026 it is not TGA approved.
Where can I buy Selank in Australia?
From this page. Check out with card, PayID, Osko or bank transfer and the vial leaves Sydney the same business day when payment clears before 12pm AEST, tracked to any Australian address.
What does Selank cost in Australia?
$79.99 for the 10mg vial, $8.00 per mg. No surcharge on PayID, Osko or bank transfer.
Is Selank legal in Australia?
Pure Peptides Australia supplies it strictly for lawful in-vitro laboratory research. It is not approved by the TGA for human or veterinary use and is not sold as a medicine, supplement or therapeutic good. Purchasers are responsible for ensuring their use complies with applicable laws.
