Selank

Selank is a synthetic peptide of seven amino acids derived from the endogenous immunomodulatory peptide tuftsin, with modifications intended to improve stability.

It is used as a neuropeptide research tool in preclinical anxiety-model and behavioral neuroscience studies.

It is popularly associated in nootropics and biohacking circles with anxiety relief and calm, clear-headed focus without the sedation attributed to conventional anxiolytics.

Selank, a synthetic analogue of the immunopeptide tuftsin, is widely discussed in nootropic and biohacking communities for its purported anxiolytic and mood-stabilizing effects. Researchers are investigating its influence on GABAergic and serotonergic signaling as well as brain-derived neurotrophic factor (BDNF), keywords that surface often in threads about anxiety relief, stress resilience, and calm focus.

It is anecdotally reported to take the edge off situational stress while leaving cognition sharp, which is why it is reputed among users seeking "calm focus" rather than blunted alertness. Some preclinical work also explores its role in immune modulation and neuroplasticity.

These represent areas of active or preclinical investigation and community interest, not outcomes established in humans.

In rodent-model research, investigators have examined Selank in relation to GABAergic signaling, monoamine balance, and expression of markers such as BDNF.

These are laboratory observations recorded in animal models and cell systems, not effects demonstrated in humans.

Selank is supplied as a lyophilized powder and kept at -20°C in a sealed container away from light.

For research use it is reconstituted with bacteriostatic or sterile water, then held at 4°C for short-term work or aliquoted at -80°C for longer storage. Each lot ships with an HPLC certificate of analysis.
