Research Overview
About PE 22-28 10mg
PE-22-28 is a potent and selective TREK-1 potassium channel antagonist engineered from spadin-related research. Laboratory studies have explored its effects on neurogenesis, synaptic plasticity and mood-related pathways.
How It Works in Research
PE-22-28 selectively inhibits TREK-1 (KCNK2) potassium channels, increasing neuronal excitability and serotonergic signalling. Preclinical studies suggest activation of CaMKII/CREB pathways, increased BDNF expression, enhanced hippocampal neurogenesis and synaptogenesis, with greater potency than spadin in laboratory models.
Research Applications
• Mood regulation • Neuroplasticity • Neurogenesis • Neuroprotection • Cognitive function • Stress resilience

Research Applications
REFERENCE RECONSTITUTION INFORMATION
Goal: Support rapid neuroplasticity, mood regulation and neuroprotection through selective TREK-1 inhibition. Schedule: Daily subcutaneous injections for 12–16 weeks (8 weeks minimum). Dose Range: 50–200 mcg daily. Reconstitution: Add 3.0 mL bacteriostatic water to one 10 mg vial (~3.33 mg/mL).
Always follow sterile preparation techniques when handling research peptides.
General Preparation
- Slowly add bacteriostatic water down the inside wall of the vial. Allow the powder to dissolve naturally and gently swirl until clear. Do not shake vigorously.
