How to Use PE-22-28
Complete guide to PE-22-28 dosing, administration, timing, and protocol recommendations.
Quick Overview
PE-22-28 is a seven-amino-acid peptide that blocks a potassium channel in the brain called TREK-1, the same target tied to depression. It is a shortened, more potent and more stable version of spadin, a natural fragment cut from the sortilin propeptide, and it was built to act like a fast antidepressant. All evidence is from rodents. There are no human clinical trials.
Dosing Guidelines
Common Dose
100-300 mcg intranasal or subcutaneous
Frequency
Once daily
Dose Range
100-500 mcg per dose
Note: Novel antidepressant peptide with rapid onset in animal studies. Works via TREK-1 channel inhibition, different from SSRIs. May be beneficial for treatment-resistant depression based on mechanism. Very limited human experience.
Administration Method
Intranasal or subcutaneous injection
Best Time to Take
Morning
May have activating effects. Morning dosing aligns with natural cortisol rhythm and avoids potential sleep interference.
Protocol Duration
Research protocols vary, often 2-4 weeks
Possible Side Effects
Not everyone experiences these. Individual responses vary.
- •Limited safety data (preclinical only)
- •Potential headache
- •Nasal irritation (intranasal use)
- •Theoretical effects on cardiac TREK-1 channels
- •Unknown long-term effects
