Selank

Selank is a synthetic peptide based on tuftsin, an immune-modulating peptide naturally found in the body, with a stabilizing tail added. The Russian clinical literature has focused on its use as an anxiolytic, with comparisons to the benzodiazepine medazepam.

Mechanistically, Selank appears to act as a positive modulator at GABA-A receptors and to influence enkephalin signaling. Most of that work is preclinical, with limited but published clinical data in generalized anxiety disorder.

The defining feature in the published comparative work is what Selank doesn’t do. It hasn’t been associated with the sedation, dependence, or withdrawal patterns seen with benzodiazepines. We use the injectable subcutaneous form in this practice, in short courses during high-stress windows.

Selank is a short-cycle tool, like Semax. Most of the published clinical work uses 5 to 14 day courses, often with breaks before re-dosing. We follow that pattern.

Patients who do best on Selank are usually using it for a defined window: a difficult run at work, travel, a transition, a high-stress family stretch. It is not a daily background medication and should not replace established care for diagnosed anxiety disorders.

Most users describe a quieter baseline within several days, rather than a fast effect from a single dose.

Anxiety and low mood often have hormonal contributors that are easier to address than they look. This protocol is often used to supplement other services like hormone optimization and wellness injectables.
