What it is claimed to help

These are the uses attached to Selank in research, clinical practice, or marketing. Listing a claim is not endorsing it — tap any of them to see every other compound carrying the same claim.

What the human evidence actually is

Grade: Early human

Small, uncontrolled, foreign-registry or single-group human studies only.

Russian clinical studies report anxiolytic effect comparable to benzodiazepines without sedation or dependence, including small comparative trials in generalised anxiety disorder. These are not replicated in Western randomised trials and are generally small.

How it is supposed to work

Tuftsin analogue; proposed modulation of GABA-A expression, enkephalin degradation, monoamine balance and BDNF.

Safety

Nasal irritation. No Western safety data.

Storage and handling

Lyophilised peptide is generally stored at 2–8 °C, or below −20 °C for long-term storage. Reconstituted in bacteriostatic water (0.9% benzyl alcohol) a solution is typically treated as usable for about 28 days refrigerated, versus roughly 24 hours for plain sterile water, which has no preservative. Add the water slowly down the vial wall and swirl — never shake, which shears peptide chains and foams the solution.

The arithmetic is the dangerous part

Whatever number a protocol or a prescriber gave you, converting it into syringe units is where a misplaced decimal becomes a tenfold error. Our calculators do that conversion and nothing else — they never invent a dose.
