What You’ll Need

  • Reconstituted peptide vial (e.g., BPC-157 5mg in 2.5–3.0 mL bac-water)

  • 1 mL insulin syringe (sterile)

  • Alcohol wipes

  • Clean workspace

  • Sharps container

  • (Optional) Medical gloves


Step-by-Step Instructions:

Step 1: Wash Your Hands and Sanitize the Area

  • Wash hands thoroughly with soap and warm water.

  • Wear gloves if available.

  • Disinfect your workspace with alcohol to prevent contamination.

Step 2: Prepare the Peptide Vial

  • Sanitize the rubber stopper of the peptide vial with an alcohol wipe.

  • Gently swirl or tilt the vial (do not shake) to ensure full mixing if recently reconstituted.

Step 3: Load the Syringe

  • Open a new sterile 1 mL insulin syringe.

  • Remove the needle cap carefully—do not touch the needle.

  • Insert the needle directly into the center (“bullseye”) of the rubber stopper.

  • Invert the vial and gently draw your desired dose (e.g., 1 mL).

  • Check for air bubbles. If present, push the plunger slightly to release them and redraw.

Pro Tip:
Even small bubbles can reduce dosage precision. Remove all visible bubbles to ensure accuracy and comfort.

Step 4: Select and Clean the Injection Site

  • Best area: around the abdomen, 2–3 inches from the belly button.

  • Clean the site with a new alcohol wipe. Choose a new spot each time to avoid irritation.

Step 5: Administer the Injection

  • Pinch a fold of skin with your non-dominant hand.

  • Hold the syringe with your dominant hand.

  • Insert the needle at a 45° angle.

  • Slowly push the plunger to inject.

  • After full injection, gently squeeze the skin as you remove the needle.

Step 6: Clean Up

  • Use a clean alcohol wipe to sanitize the injection site.

  • Carefully recap the needle using a flat surface (never your hands).

  • Dispose of the used syringe in a sharps container only.


Storage & Safety Guidelines

  • Storage:
    • Store reconstituted peptides in the fridge (2°C–8°C / 35°F–46°F).
    • Use within 30–45 days.
    • Lyophilized powder can be frozen up to 2 years before reconstitution.

  • Needle Safety:
    • Never reuse needles—even once.
    • Always use new, sterile equipment.
    • Avoid touching needle tips or rubber stoppers after sanitizing.

Respect the Ritual

Peptides are powerful tools for healing, recovery, and performance—but only when used correctly. By practicing precise technique, maintaining a sterile environment, and respecting your body, peptide injections can become a seamless part of your wellness practice.

Always consult your healthcare provider before beginning peptide injections.
