Selank is available in Australia from Peptide Warehouse with fast domestic shipping to all states and territories.
Selank is a synthetic nootropic peptide developed by Russian scientists, derived from a naturally occurring immune-regulating peptide called tuftsin. Researchers study it for its ability to reduce anxiety and mental tension without causing the sedation or dependence issues seen with conventional anti-anxiety drugs. In preclinical models, it has shown an ability to calm anxious behaviour while actually improving memory and cognitive clarity at the same time — a combination that makes it an interesting research tool for studying how the brain manages stress and learning simultaneously.
Supplied as lyophilised powder at 99.0% HPLC purity, independently verified by third-party testing. 10mg per vial. Fast domestic shipping across Australia from our Melbourne warehouse — batch-specific COA available in our COA Library.

Selank (CAS 129954-34-3, MW 751.87 Da, sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide derived from the endogenous immunopeptide tuftsin. In preclinical research, Selank has been studied for: anxiolytic effects in elevated plus maze and light-dark box models without sedation or motor impairment; modulation of GABA-A receptor sensitivity via a benzodiazepine-like mechanism without BZD binding; elevation of BDNF and NGF expression in hippocampal tissue; improvement in memory consolidation and learning in rodent models; modulation of serotonin and dopamine turnover in limbic regions; and immunomodulatory effects via tuftsin receptor activity. For research use only.
Selank and Semax are both synthetic neuropeptides developed by the same Russian research institution but with distinct primary profiles. Semax (derived from ACTH(4-10)) is studied as an activating nootropic — it sharpens focus, increases cognitive processing speed, and upregulates BDNF through a different pathway. Selank (derived from tuftsin) is primarily studied as an anxiolytic — it reduces anxiety and mental noise, improves memory under stress, and calms limbic activity without sedation. Semax is the focusing compound; Selank is the calming compound. Both are available from Peptide Warehouse for separate or combined research protocols. Not for human consumption — for research use only.
A key distinguishing feature of Selank in the research literature is its anxiolytic-without-sedation profile. In rodent studies using rotarod tests and open field locomotion assessments, Selank does not produce the motor coordination deficits or sedation observed with benzodiazepines. The proposed mechanism — modulation of GABA-A receptor sensitivity rather than direct receptor agonism — may explain this distinction. Preclinical dependence models have not demonstrated the tolerance or withdrawal profiles associated with classical BZD anxiolytics. These are research findings in animal models.

Reconstitution: Draw 1–2mL of bacteriostatic water into a clean 31G insulin syringe. Inject slowly down the inside wall of the Selank vial. Gently swirl until fully dissolved. The solution should be clear and colourless. Common concentration: 1mL BAC water = 10mg/mL. Storage: Lyophilised — store at −20°C for up to 24 months. Reconstituted — refrigerate at 2–8°C and use within 28 days. Protect from light.
Selank is legal to purchase in Australia for legitimate laboratory research purposes. It is not listed as a scheduled substance under the Poisons Standard when sold for research use only. Purchasers must be 18+ and confirm research-only use. It is not TGA-approved for human consumption, therapeutic, or veterinary use. Our Selank 10mg is independently verified at 99.0% HPLC purity with full COA documentation. Peptide Warehouse dispatches nationwide from our Melbourne warehouse via Australia Post.
Tuftsin is an endogenous tetrapeptide (Thr-Lys-Pro-Arg) produced by enzymatic cleavage of IgG in the spleen. It is a natural immunostimulatory peptide that binds tuftsin receptors on phagocytes. Selank incorporates the full tuftsin sequence as its N-terminal core (residues 1–4) and adds a Pro-Gly-Pro tripeptide to the C-terminus to slow carboxypeptidase degradation — extending half-life while preserving both tuftsin receptor activity and adding GABAergic modulation. Not for human consumption — for research use only.
