Selank

Selank is a synthetic tuftsin analog used off‑label for anxiety reduction, stress relief, and, to a lesser extent, cognitive enhancement and focus. Community users typically dose 500 µg daily, with reported amounts ranging from 100 µg to 10 mg, and most take it each day without a fixed schedule. The main caveat is that the off‑label evidence base is thinner than the discourse suggests, and while serious adverse events are rare, occasional reports mention altered sleep or vivid dreams, with injection‑site reactions not being a consistent theme.

Research Evidence

Evidence shape

The evidence for Selank is limited, with around 5 human studies, mostly focused on treatment and diagnostic research. These studies cover a few indications, but the overall breadth and quality of the research are constrained by the small number of sponsors and lack of blinded trials with results. The field is also marked by the absence of larger, registered trials, with most research being exploratory or limited in scope.

Selank dosing & protocol

How Selank is dosed across research, clinician, and community sources — each evidence tier kept separate so the dose range, frequency, timing, and cycling stay visible without flattening different levels of evidence.
