PE-22-28 (PE-22-28 (spadin analog, TREK-1 inhibitor)) is a Ion channel inhibitor peptide researched for rapid antidepressant effects (4 days vs 4-6 weeks for SSRIs), hippocampal neurogenesis, enhanced synaptogenesis. Common dosages range from 100-500 mcg daily administered once daily. Below are the most frequently asked questions.
Frequently Asked Questions About PE-22-28
What is PE-22-28?
PE-22-28 (PE-22-28 (spadin analog, TREK-1 inhibitor)) is a Ion channel inhibitor peptide. Synthetic shortened analog of spadin with enhanced TREK-1 potassium channel specificity and brain stability. It is researched for rapid antidepressant effects (4 days vs 4-6 weeks for SSRIs), hippocampal neurogenesis, enhanced synaptogenesis.
What is the recommended PE-22-28 dosage?
Common dosages range from 100-500 mcg daily, administered once daily via subcutaneous injection (proposed). Cycles typically run 4-8 weeks.
What are the side effects of PE-22-28?
Minimal toxicity in animal models. Potential hypertension from enhanced monoamine activity. Human safety unknown. GABAergic disruption possible.
Is PE-22-28 legal?
Not FDA-approved. Investigational research peptide only.
What is the half-life of PE-22-28?
The half-life of PE-22-28 is 14-23 hours in rodents, which determines the once daily dosing schedule.
How do you reconstitute PE-22-28?
Add bacteriostatic water to the lyophilized PE-22-28 vial. Let the water run down the side — never spray on the powder. Swirl gently. Use our peptide calculator for exact amounts.
Can you stack PE-22-28 with other peptides?
Could theoretically pair with SSRIs for enhanced antidepressant effects through complementary serotonergic mechanisms.
Where can you buy PE-22-28?
PE-22-28 is available as a research chemical from vetted suppliers with third-party COA testing.
How long does it take PE-22-28 to work?
Initial effects may be noticed within 1-2 weeks, with more significant results typically appearing by weeks 4-8 of a 4-8 weeks cycle.
What makes PE-22-28 unique?
Demonstrates antidepressant onset in 4 days versus 4-6 weeks for conventional medications — if human efficacy confirms, this would be the fastest-acting peptide antidepressant.
