Intranasal calculator
Metered spray concentration and volume calculations with explicit pump assumptions.
Vial: a known mass already in solution, to find the amount in each spray. Powder: a planned number of doses, to find the powder and liquid to prepare.
How much peptide you have total (e.g., a 100mg vial).
Enter the final volume of the route-compatible diluent specified by the formulation source. Do not substitute ordinary or non-sterile water.
Enter the documented output for the exact metered pump. The 0.10 mL default is a calculation example, not a universal specification.
Enter your target dose per use. You can choose mg or mcg.
Peptide per spray
1 mg (1000 mcg)
A target amount of 5 mg corresponds to 5 whole sprays (exact: 5).
- Concentration
- 10 mg/mL
- Whole sprays needed
- 5
- Exact sprays
- 5
- Total sprays available (approx.)
- 100
With a final prepared volume of 10 mL, 100 mg total material and a verified pump output of 0.1 mL, each spray calculates to 1 mg (1000 mcg).
Calculation reference only. Confirm that the exact formulation, diluent and pump are supported for the intended route.
Target dose per use (in micrograms) for your planned schedule.
How many total doses you want to make (used to compute total powder and total liquid needed).
Use the documented output for the exact metered pump. The 0.10 mL default is a calculation example, not a universal pump specification.
If your dose requires multiple sprays, enter that number here.
Powder required
30 mg
Enough for 60 doses of 500 mcg, at 1 spray per dose.
- Volume required
- 6 mL
- Concentration
- 5 mg/mL
- Total sprays
- 60
Calculation reference only. Use a route-compatible formulation, diluent and metered pump supported by the source instructions.
Spray volume helper
Divide a prepared volume by a documented usable spray count to estimate the volume in each spray.
Total route-compatible prepared volume placed in the bottle.
Enter a documented or validated usable spray count for the assembled pump. Priming loss should be excluded.
Calculated volume per spray
0.1 mL
5 mL of prepared solution divided across 50 usable sprays.
- Entered usable sprays
- 50
This division does not validate pump output. Use the exact pump’s documentation or a validated calibration method.
