Questions (9)

What is Selank?

Selank (Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro; tuftsin analogue)). Synthetic heptapeptide analogue of the immunopeptide tuftsin. Modulates GABA/serotonin systems, BDNF expression, and enkephalin metabolism; studied as an anxiolytic/nootropic primarily in Russian clinical literature.

What is Selank used for?

Commonly discussed uses: anxiety modulation (research), cognitive support (anecdotal). There is both human and animal/preclinical research, though the depth and quality vary by indication. Note: most uses are not approved indications.

How does Selank work?

Mechanism: Synthetic heptapeptide analogue of the immunopeptide tuftsin. Modulates GABA/serotonin systems, BDNF expression, and enkephalin metabolism; studied as an anxiolytic/nootropic primarily in Russian clinical literature.

Is Selank safe?

Reported considerations: anecdotal: well tolerated; mild fatigue/nasal irritation (intranasal). There is both human and animal/preclinical research, though the depth and quality vary by indication. Approved/registered as a medicine in Russia; not approved in AU/US/UK. This is not a safety endorsement; safety data for unapproved compounds is incomplete.

What is the typical dose of Selank?

Commonly cited ranges (educational reference, not a recommendation): low 250mcg, typical intranasal 250-500mcg/day, high 900mcg/day. Administration: intranasal, subcutaneous. Half-life: short.

Is Selank legal in Australia?

Australian status: Not ARTG-registered; research. Approved/registered as a medicine in Russia; not approved in AU/US/UK. General regulatory context: most active peptides are Schedule 4 and require a prescription; import via the Personal Importation Scheme requires a valid Australian prescription for prescription-only goods.

How do you store Selank?

Reconstitution/storage reference: intranasal pre-mixed; SC 2ml BAC per 5-10mg; storage: refrigerated.

What is Selank commonly stacked with?

Commonly discussed combinations (anecdotal for unapproved compounds): Selank + Semax (nootropic stack, anecdotal). Stacking increases interaction/safety uncertainty.
