PE-22-28

THE RAPID MOOD LIFTER

Spadin Analog; Shortened Spadin

PE-22-28 is a synthetic peptide derived from spadin that blocks TREK-1 potassium channels in the brain. This produces rapid antidepressant effects - often within days rather than the weeks typical of SSRIs. It promotes neurogenesis, protects neurons, and may help with stroke recovery. It's an exciting option for those seeking fast-acting mood support.
