PE-22-28 10mg

CAS: N/A (research peptide)MW: 587.58 Da7 amino acidsSKU: PE2228-10

PE-22-28 is a synthetic peptide derived from spadin, a natural TREK-1 potassium channel blocker. Research demonstrates rapid antidepressant-like effects through TREK-1 channel inhibition, increased hippocampal neurogenesis, and enhanced serotonergic neurotransmission. It produces antidepressant effects within days rather than weeks.
