P1 Peptides Injector Pen Kit — Complete Usage Guide

For Research Use Only

What's Included in Your Kit

  • P1 Peptides reusable injector pen
  • Replaceable peptide cartridge
  • Pen needles
  • Protective storage cap

8-Step Instructions

Step 1 — Prepare Pen
Remove the cap and inspect all components. Ensure the pen body is clean and undamaged before use.

Step 2 — Insert Cartridge
Unscrew the cartridge holder from the pen body. Insert your peptide cartridge with the rubber stopper facing the needle end. Reattach the cartridge holder firmly.

Step 3 — Assemble Parts
Securely screw pen body components back together until you feel resistance. Do not overtighten.

Step 4 — Attach Needle
Attach a new needle to the cartridge tip and screw on until secure. Remove the outer and inner needle caps.

Step 5 — Prep Tip
Prime the pen before first use. Dial 2 units and press the injection button with the needle pointing upward until a small drop appears at the tip. This removes air from the cartridge.

Step 6 — Select Dose
Dial to the required dose using the dose knob. The dose window displays the selected units clearly. Dial back if you pass your target dose.

Step 7 — Dispense
Press the injection button fully and hold until the dose window returns to zero. Hold for 5–10 seconds after injection before withdrawing.

Step 8 — Discard After Use
Safely remove the used needle using the outer cap and dispose of in an approved sharps container. Never reuse needles. Store pen with protective cap on.

Storage Guidelines

  • Store pen at room temperature, away from heat and direct light
  • Refrigerate unused cartridges at 2°C–8°C
  • Do not freeze cartridges
  • Once in use, cartridges are stable at room temperature for up to 28 days
