Intranasal Peptide Calculator
Pick a peptide or enter a custom vial, then work out the concentration, the amount in each pump actuation, the actuations per bottle and the cost of each actuation.

The formula
How this is calculated
Concentration is the vial’s peptide in mcg divided by the BAC water added. The amount per actuation is that concentration divided by the pump’s actuations per mL, and actuations per bottle is the bottle volume times actuations per mL, rounded down because a part-filled last actuation is not a full one.
Cost per actuation divides the vial price by the actuations in one bottle, so it treats one vial as filling one bottle.
Pumps vary, so check the volume per actuation printed on your pump (0.05 mL per actuation is 20 per mL).
Check the vial size against the batch certificate of analysis for the product in hand. For research use only; this tool converts units and does not recommend amounts.

Questions
Frequently asked questions.
How does an intranasal peptide calculator work?
It divides the peptide amount by the liquid volume to get concentration, then multiplies by the volume each pump actuation delivers. For example, 10 mg in 10 mL is 1 mg/mL, so a 0.1 mL actuation contains 0.1 mg (100 mcg).
How do I find my pump’s actuation volume?
Check the pump’s specification first; many nasal pumps deliver around 0.1 mL per actuation, but this varies. To measure it, count how many actuations it takes to empty a known volume. A 10 mL bottle that empties in 100 actuations delivers 0.1 mL each.
How many actuations are in a nasal spray bottle?
Divide the total liquid volume by the actuation volume. A 10 mL bottle with a 0.1 mL pump gives about 100 actuations, minus a few lost to priming the pump.
Does the calculator work for Semax, Selank and other peptides?
Yes. The math is the same for any peptide. Enter the milligrams on the vial label and the liquid volume, and the result applies whatever the compound.
Is this calculator dosing advice?
No. It only converts amount, volume and concentration. It does not recommend amounts or protocols. All peptides listed on PepLookup are for research use only.
