Description
Selank Capsules | GABAergic Anxiolytic Neuropeptide — Research Grade
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic analogue of the endogenous immunomodulatory peptide tuftsin, registered in Russia as an anxiolytic drug (TP-7). This oral capsule format (10mg per capsule, 60 capsules) supports research protocols examining GABAergic neurotransmission, HPA axis modulation, and neuroplasticity without the sedation associated with classical benzodiazepines.
Mechanism of Action
- GABAergic potentiation — enhances GABA-A receptor sensitivity without direct binding, producing anxiolytic effects in animal models
- BDNF upregulation — increases brain-derived neurotrophic factor in hippocampal regions associated with stress response
- HPA axis normalisation — attenuates corticosterone and CRH release in chronic stress models
- Enkephalin stability — inhibits enkephalin-degrading enzymes, prolonging endogenous opioid peptide activity
Research Areas
Selank is studied in anxiety models, post-traumatic stress, immune function (tuftsin-like activity), and cognitive-enhancing protocols. Commonly paired with Semax for combined GABAergic/adrenergic neuropeptide research panels.
