    What Is PE 22-28 8mg?

    PE 22-28 8mg Vial Overview

    PE 22-28 (Spadin analog) is a heptapeptide that blocks the TREK-1 potassium channel, a novel antidepressant mechanism. It produces rapid antidepressant-like effects with significantly faster onset than traditional SSRIs, enhances hippocampal neurogenesis, and increases serotonergic and noradrenergic neurotransmission.

    PE 22-28 8mg Mixing Instructions

    1. 1Remove the vial from storage and allow it to reach room temperature (10–15 minutes).
    2. 2Wash hands thoroughly and prepare a clean workspace with all supplies.
    3. 3Using a sterile syringe, draw the appropriate volume of bacteriostatic water.
    4. 4Clean the rubber stopper of the vial with an alcohol prep pad.
    5. 5Insert the needle at a slight angle and slowly inject the diluent down the inner wall of the vial.
    6. 6Gently swirl or roll the vial until fully dissolved; the solution should appear clear and colorless.
    7. 7Label the vial with reconstitution date and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light. Use within 2–4 weeks.
