PE-22-28 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
The most common research dosage for PE-22-28 is 100-500 mcg daily, administered once daily via subcutaneous injection (proposed). Typical cycles run 4-8 weeks. With a half-life of 14-23 hours in rodents, timing matters for optimal results.
What Is PE-22-28 and Why Does Dosing Matter?
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. Getting the dosage right is critical — too little may produce no measurable effect, while excessive amounts increase risk without proportional benefit.
The standard research dosage for PE-22-28 has been established through preclinical studies and community protocols. This guide covers the evidence-backed dosing range, timing, and cycle structure.
What Is the Recommended PE-22-28 Dosage?
The most widely used PE-22-28 dosage is 100-500 mcg daily, administered once daily via subcutaneous injection (proposed).
Beginners should start at the lower end of this range and titrate upward only if needed. The half-life of PE-22-28 is 14-23 hours in rodents, which directly determines how often you need to dose to maintain stable blood levels.
For PE-22-28 specifically, the 4-8 weeks cycle length is standard. Longer isn't always better — Ion channel inhibitor peptide compounds require cycling to maintain receptor sensitivity.
When Should You Dose PE-22-28?
With a half-life of 14-23 hours in rodents, timing your PE-22-28 administration affects peak blood levels. Most protocols call for once daily.
For peptides administered before bed (common with GH-related compounds), the goal is to amplify the natural nocturnal growth hormone pulse. For healing peptides, proximity to the injury site via local injection can improve outcomes.
Calculate Your PE-22-28 Dose

Open Calculator →How Do You Reconstitute PE-22-28?
PE-22-28 typically comes as a lyophilized (freeze-dried) powder. Reconstitute with bacteriostatic water — never saline or sterile water, as BAC water contains 0.9% benzyl alcohol that prevents bacterial growth and extends shelf life to 4-6 weeks.
Use our peptide dosing calculator to determine the exact amount of BAC water to add based on your vial size and desired dose per injection.
How Long Should a PE-22-28 Cycle Last?
Standard PE-22-28 cycles run 4-8 weeks. This timeframe is based on the compound's mechanism and the time needed to observe measurable effects.
Superior TREK-1 inhibition (IC50: 0.12 nM vs 40-60 nM for native spadin) with rapid antidepressant effects in rodent stress models. 4-day onset compared to weeks for conventional antidepressants. No human clinical trials.
What Side Effects Can Affect Dosing?
Minimal toxicity in animal models. Potential hypertension from enhanced monoamine activity. Human safety unknown. GABAergic disruption possible.
If side effects emerge, the first step is typically reducing the dose rather than discontinuing entirely. Most PE-22-28-related side effects are dose-dependent.
How Does PE-22-28 Dosing Change When Stacking?
Could theoretically pair with SSRIs for enhanced antidepressant effects through complementary serotonergic mechanisms.
When stacking, some researchers reduce individual peptide doses by 20-30% since synergistic effects mean full doses of each aren't always necessary.
What Is the Bottom Line on PE-22-28 Dosing?
Start at 100, dose once daily, and run cycles of 4-8 weeks. Monitor your response and adjust within the established range.
Source matters — always use research-grade PE-22-28 from vendors with third-party COA testing. Underdosed or contaminated products are the most common reason for poor results.
