Research cycle phases

Units and volumes recompute from your Step 1 concentration (2 mL BAC → 5.00 mg/mL · 50.0 mcg/unit). Doses below are once daily during the course — not weekly.

Standard course

Secondary educational tables commonly discuss ~50–200 mcg once daily (sometimes up to ~500 mcg in higher write-ups). PE-22-28 is a TREK-1–related spadin analog studied for antidepressant/neuroplasticity signals in preclinical work — human dose not established.

~10.5 mg mg total peptide over this 84-day course at 50 mcg → 100 mcg → 200 mcg per injection (phase ladder). Each vial holds 10 mg.

Bacteriostatic water

2 × 3 mL or 1 × 10 mL

2 mL BAC per vial × 2 vials = 4.0 mL total. Buy as 2× 3 mL bottles or 1× 10 mL bottle (whichever you stock).

U-100 insulin syringes (100-unit)

84+ syringes

About one 100-unit syringe per injection for this schedule. Keep a few spares.

Wipe vial stopper and injection site each time. Dispose needles in a proper sharps container.

Reconstitution steps

  1. Allow the lyophilized 10 mg PE-22-28 vial and bacteriostatic water to reach room temperature.
  2. Draw 2.0 mL bacteriostatic water (default for this guide).
  3. Inject BAC slowly down the inner wall of the vial — avoid blasting the powder cake.
  4. Gently swirl or roll until the solution is clear. Do not shake hard (foaming).
  5. Label with recon date and concentration (e.g. "5.0 mg/mL — 2 mL BAC").
  6. Refrigerate at 2–8 °C (35–46 °F), protected from light. Prefer using a reconstituted multi-dose vial within ~28 days with sterile technique.

Storage

Lyophilized

Keep dry powder cold and dark when possible (−20 °C / −4 °F preferred for long-term research stock).

Reconstituted

Refrigerate at 2–8 °C (35–46 °F). Avoid freeze–thaw of the working solution. Prefer finishing within ~28 days.

  • ·Write recon date and BAC volume on the label.
  • ·Protect from light during storage.
  • ·Discard if cloudy, particulates, or odd odor appear after reconstitution.

Protocol notes

  • ·Spadin-optimized analog targeting TREK-1 potassium channel biology in preclinical depression models.
  • ·Calculator: 0.1 mg = 100 mcg.
  • ·Research use only.

Research context & considerations

PE-22-28 is derived from sortilin propeptide/spadin research on TREK-1 inhibition and neuroplasticity. Research vials are not approved antidepressants.

  • ·CNS-active experimental peptide — unknown long-term human safety.
  • ·Not FDA-approved.
  • ·Pregnancy out of scope.
