Injection Dosing
Need a calculator for subcutaneous injection dosing?
Our general Peptide Calculator computes reconstitution volumes and insulin syringe units for injectable research peptides.
Open Peptide CalculatorHow to Use This Nasal Spray Calculator
Enter Peptide Amount
Input the total milligrams of peptide dissolved in your nasal spray bottle. Check your vial label for the mg content.
Set Total Volume
Select the total liquid volume in your spray bottle. This includes the reconstitution solvent (bacteriostatic water or saline).
Choose Desired Dose
Select how many milligrams of peptide you want per administration. The calculator tells you how many sprays that requires.
Nasal Spray Calculation Formulas
Concentration = Peptide Amount ÷ Total Volume = mg/mL
mg per Spray = Concentration ÷ Sprays per mL
Sprays per Dose = Desired Dose ÷ mg per Spray
Total Doses = Peptide Amount ÷ Desired Dose
Common Questions
How many sprays per mL does a standard nasal spray bottle deliver?
Most standard nasal spray pumps deliver approximately 0.1mL per actuation, which equals 10 sprays per mL. This calculator uses that standard. If your spray bottle has a different output, adjust your total volume accordingly.
What solvent should I use for nasal spray reconstitution?
Bacteriostatic water or sterile saline (0.9% NaCl) are the most commonly referenced solvents for nasal peptide preparations in research literature. Use our Bac Water Calculator for help with reconstitution volumes.
Which peptides are researched via nasal delivery?
Published research has explored nasal delivery for peptides including BPC-157, PT-141, Selank, Semax, and various nootropic peptides. Nasal delivery offers rapid absorption through the nasal mucosa, bypassing first-pass metabolism.
How is nasal dosing different from injection dosing?
Nasal delivery uses a spray pump rather than a syringe, so dosing is measured in number of sprays rather than syringe units. The concentration calculation is the same, but the delivery volume per spray is fixed by the pump mechanism (~0.1mL per spray). For injection dosing, use our Peptide Calculator.
