How to Make a Peptide Nasal Spray (Step-by-Step Guide + Do's & Don'ts)

Materials Needed

• Lyophilized peptide powder
• Bacteriostatic water (0.9% benzyl alcohol)
• Sterile empty nasal spray bottle (10-30ml)
• Sterile syringe with needle
• Alcohol wipes
• Sterile gloves

Step-by-Step Instructions

Step 1: Prepare Your Workspace

Clean and sanitize your work surface thoroughly. Wash your hands and put on sterile gloves. Lay out all materials on a clean surface.

Step 2: Calculate Dosage

Determine the desired concentration for your nasal spray. Common concentrations range from 200-500mcg per spray. Calculate the total volume of bacteriostatic water needed based on your peptide amount and desired concentration.

Step 3: Reconstitute the Peptide

Using a sterile syringe, draw up the calculated amount of bacteriostatic water. Inject slowly down the inside wall of the peptide vial—never directly onto the powder. Allow the peptide to dissolve naturally without shaking.

Step 4: Transfer to Nasal Spray Bottle

Once fully dissolved, draw the peptide solution into a sterile syringe. Remove the spray pump from your nasal bottle and carefully transfer the solution into the bottle. Replace the spray pump securely.

Step 5: Prime the Pump

Prime the nasal spray pump by spraying 5-10 times into a tissue until you get a consistent fine mist. This ensures accurate dosing with each spray.

Step 6: Test Spray Volume

Most nasal spray pumps deliver 0.1ml per spray. Test this by doing 10 sprays into a small measuring container to verify you're getting 1ml total.

Important Do's

• DO keep everything sterile throughout the process
• DO store in the refrigerator when not in use
• DO label your spray with the peptide name, concentration, and date prepared
• DO use within 30 days of reconstitution
• DO prime the pump before each use if it hasn't been used in 24 hours

Important Don'ts

• DON'T spray directly onto the peptide powder during reconstitution
• DON'T shake the vial—swirl gently if needed
• DON'T freeze the nasal spray
• DON'T share nasal spray bottles with others
• DON'T use if the solution appears cloudy or discolored
• DON'T use regular water—always use bacteriostatic water

Storage and Shelf Life

Store your prepared peptide nasal spray in the refrigerator at 2-8°C (36-46°F). The solution should remain stable for up to 30 days when stored properly. Always check for any discoloration or particles before each use.
