About
What is Selank 20mg?
Selank is a Russian-synthesized heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) based on the immunoregulatory tetrapeptide tuftsin, with stabilizing proline residues added to extend its biological half-life. It has been characterized in Russian neuropeptide and immunology literature.
Mechanism of Action
Published research describes Selank modulating GABAergic neurotransmission, increasing BDNF expression, and influencing enkephalin-related pathways. Studies also note immune modulation effects on cytokine balance.
Discovery & Context
Developed at the same Moscow-based institute as Semax. Used in Russian clinical practice for anxiety research but not approved in the US or EU.
Research use only. Language such as "may," "appears to," and "has been shown in published studies" is used throughout to reflect the pre-clinical nature of this literature. Not intended for human consumption, diagnosis, or treatment.
Background
Research Context
Published research literature covers the following areas:
- Anxiolytic pathway models
- GABAergic neurotransmission
- BDNF expression studies
- Tuftsin-derivative immunology
- Enkephalin pathway research
LAR supplies this compound as a reference standard to qualified laboratories. No dosing schedules, administration methods, or human-use guidance is provided or implied.

Questions
Frequently Asked
Is this FDA approved?
No. Research peptides supplied by LAR are reference materials for laboratory investigation. They are not approved by the FDA or any national regulatory body for human use.
Does this vial require reconstitution?
Yes. Vials ship as lyophilized powder, giving your lab control over solvent selection and final concentration. Reconstitution should follow your laboratory's standard practice.
How is purity verified?
Each manufacturing batch is tested by an independent third-party laboratory using HPLC-UV analysis. The full report, including chromatogram and mass spectrometry, is available above.
How long does shipping take?
Orders ship within 1–2 business days via discreet packaging.
