Selank · How it works
Enkephalins stay longer
Enkephalins are natural calming opioid peptides that the blood breaks down in minutes. Selank blocks the enzymes that clear them. Enkephalins stay active longer and soften the stress response. Blocking the opioid receptor removes part of Selank's calm, which shows this path is real.
