To ensure safe and effective use of Peptide Products, like LL37, it’s important to follow correct preparation, handling, and injection techniques. Below is a summary of the most essential steps. For detailed guidance, please refer to the official Product Leaflet included with your vial. You can also view the the Leaflet online at the right bottom of the product page.

• Inspect the solution before each use by gently tipping or swirling the vial or preloaded syringe once or twice.
• Do not use if the solution appears cloudy, discolored, or contains particles.
• Peptide products are typically supplied as a lyophilized (freeze-dried) powder.
• Reconstitute using bacteriostatic water.
• Inject slowly along the vial wall and swirl gently (do not shake) until fully dissolved and clear.
• This peptide is intended for subcutaneous injection using insulin syringes (up to 16 mm needle length).
• Always use a new, sterile syringe and needle for every injection.
• Maintain aseptic technique and never reuse syringes.
• Rotate the injection sites (e.g., abdomen, thighs, or upper arm) to avoid local irritation or tissue damage.
• Before injecting, check that the syringe is correctly loaded: a small drop of solution should appear at the needle tip. If not, discard the syringe and prepare a new one.
• Refer to sections E–G on pages 10–11 of the Product Leaflet for visual instruction, if available.
• Store the lyophilized powder refrigerated at 2–8 °C.
• After reconstitution, use within 7–14 days, keeping the solution refrigerated.
• Do not freeze. Protect from light.
