Research vial labelled Selank, a Cognitive peptide studied in preclinical and clinical literature

Selank

The file here is mostly preclinical work plus clinic and community practice, not registrational trials.

Anxiolytic research analog of tuftsin. As with Semax, the clinical work is Russian-language.

Timing and cycling in the literature

Usually dosed in the morning window

Daily, usually intranasal

Studied for anxiolytic effect across the working day without the sedation profile of a benzodiazepine.

Reported cycle: 2 weeks on, 2 weeks off

Like Semax, the Russian clinical use is ten to fourteen day courses with gaps between them.

Watch for: Drowsiness at higher amounts and nasal irritation from intranasal use.

What it conflicts with

Three separate questions, kept separate. A hard stop means the mechanisms must not run together at all and timing does not fix it. A syringe rule means the same day is fine but one barrel is not. Redundancy is not dangerous, it is paying twice to hit one target.

  • Hard stopBody level hard stop

    Selank + Methylene blue and any serotonergic drug

    Do not run with methylene blue or serotonergic medication

    Methylene blue inhibits MAO-A. Stacked with serotonin-raising agents (SSRIs, SNRIs, MAOIs, tricyclics, tramadol, St John's Wort) the risk is serotonin syndrome. Timing does not fix this one, it is a mechanism conflict.

    Selank + Semax

    Commonly paired, still start separately

    The Russian literature pairs an anxiolytic with a stimulating analog and reports no interaction. Introduce them a week apart so you know which one is doing what.

Most syringe compatibility claims here are practice and expert consensus, not peer reviewed mixing studies. A clear liquid after mixing does not prove the compounds are still active, and cloudiness, particles or gelling means discard. Active cancer, pregnancy, major cardiac care and heavy immunosuppression override every stack preference on this page.

The studies

Human trials: No completed human efficacy trial that establishes a dose for the use people are chasing.

Open questions: Treat published dosing as observed practice, not a validated protocol.
