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.
PE-22-28 is typically reconstituted with bacteriostatic water (BAC water). The standard dosage of 100-500 mcg daily is administered once daily via subcutaneous injection (proposed). Use our peptide calculator for exact mixing ratios.
How Do You Reconstitute PE-22-28?
PE-22-28 is supplied as a lyophilized (freeze-dried) powder that must be reconstituted before use. Proper reconstitution is critical for accurate dosing and maintaining stability.
This guide covers the step-by-step process for mixing PE-22-28 with bacteriostatic water to achieve your target concentration.
What Supplies Do You Need?
To reconstitute PE-22-28, you need: the PE-22-28 vial (lyophilized powder), bacteriostatic water (BAC water with 0.9% benzyl alcohol), insulin syringes (typically 1mL/100-unit), alcohol swabs, and a clean workspace.
Important: Always use bacteriostatic water — not sterile water or saline. BAC water's benzyl alcohol prevents bacterial contamination, extending the usable life of reconstituted PE-22-28 to 4-6 weeks.
Step-by-Step PE-22-28 Reconstitution
Step 1: Clean the vial tops of both the PE-22-28 and BAC water with alcohol swabs.
Step 2: Draw the calculated amount of BAC water into an insulin syringe. Use our peptide calculator to determine the exact amount.
Step 3: Insert the needle into the PE-22-28 vial at an angle, and let the water run down the side of the glass — never spray directly onto the powder as this can damage the peptide bonds.
Step 4: Gently swirl (do not shake) the vial until the powder is fully dissolved. The solution should be clear.
Step 5: Label the vial with the date and concentration. Store at 2-8°C.

Open Calculator →How Do You Dose Reconstituted PE-22-28?
After reconstitution, the standard PE-22-28 dose is 100-500 mcg daily administered once daily via subcutaneous injection (proposed). The number of units on your insulin syringe depends on how much BAC water you added.
Our calculator will tell you exactly how many units to draw for your dose based on your specific reconstitution ratio.
How Do You Store Reconstituted PE-22-28?
Store reconstituted PE-22-28 at 2-8°C (standard refrigerator temperature). Use within 4-6 weeks. Keep away from light and temperature fluctuations.
Unreconstituted PE-22-28 powder can be stored at -20°C for 12+ months. Once you reconstitute it, the clock starts.
Bottom Line
Reconstituting PE-22-28 is straightforward — add BAC water, swirl gently, refrigerate. The key is using the right amount of water for accurate dosing. Use our peptide calculator every time.

Frequently Asked Questions
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: 100-500 mcg daily administered once daily via subcutaneous injection (proposed). Cycle length: 4-8 weeks. Half-life: 14-23 hours in rodents. Use our peptide calculator for exact reconstitution math.
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 safe?
PE-22-28 has shown a preliminary safety profile in research. Not FDA-approved. Investigational research peptide only. All research should follow appropriate safety protocols.
