Brief Description

Heptapeptide created by combining the immunomodulatory peptide tuftsin with a stabilizing Pro-Gly-Pro sequence that extends its half-life. Selank modulates brain-derived neurotrophic factor (BDNF) expression and influences the balance of IL-6, T-helper, and enkephalin systems. It acts on both immune and neurological pathways without sedation or dependence in research models. Research areas include anxiolytic mechanisms, immune modulation, cognitive function, and BDNF expression in the hippocampus. For research use only — not for human consumption.

Batch 002 Transparency Note
Transparency update

Due to recent supply chain and international shipping disruptions, some Batch 002 inventory may include vials produced at different points within our supplier’s production cycle. As a result, researchers may notice minor packaging variations, including differences in vial caps.

These products were sourced from the same established manufacturers we have worked with for ongoing quality and third-party testing. That said, we want to be transparent that Batch 002 may not represent a single uninterrupted production run.

We are already working with our suppliers to strengthen batch-control, packaging, and documentation protocols before Batch 003.
