Selank is a synthetic peptide based on a naturally occurring regulatory peptide. People report using it for focus, calm, and cognitive outcomes.

What is measured

The effect index reflects self-reported cognitive outcomes among people who already use Selank, read against their own baseline with a 95 percent credible interval.

What is established

Nothing yet. The estimate sits close to zero and the interval still includes no effect. We publish this because absence is a finding. A result that has not separated from no effect is recorded plainly, not omitted.

What is not established

This is not a negative verdict and it is not a positive one. It is an open question with too little evidence so far to answer. It is not medical advice. We never supply or prescribe.
