This nasal spray peptide calculator shows how much peptide each spray delivers and how many sprays a bottle holds.
How to use the Nasal Spray Peptide Calculator
- Enter the peptide in bottle, or tap a preset.
- Enter the bottle volume, or tap a preset.
- Enter the volume per spray, or tap a preset.
- Enter the desired dose and choose mcg or mg (optional).

About this calculator
Metered spray pumps deliver a fixed volume per actuation. Prime the pump before first use, which wastes a few sprays, and hold the bottle upright for consistent volume.
Frequently asked questions
How do I measure my pump’s spray volume?
Weigh the bottle, spray 10 times, and weigh again. Each 0.1 g lost per spray is about 0.1 mL for water-based solutions.
