How the Math Works
A nasal research bottle holds a fixed amount of peptide dissolved in a fixed volume of solution, and a metered pump delivers a set volume with each actuation. From those three figures everything else follows:
- Concentration (mg/mL) = peptide in bottle (mg) ÷ solution volume (mL)
- Amount per spray = concentration (mg/mL) × volume per spray (mL)
- Total sprays = solution volume (mL) ÷ volume per spray (mL)
Example: a 10 mg bottle in 5 mL of solution is 2 mg/mL. With a standard 0.1 mL pump, each spray delivers 0.2 mg (200 mcg), and the bottle holds 50 sprays.
Metered nasal pumps differ — most deliver around 0.1 mL, but fine-mist and larger pumps differ. Use the preset menu or enter the exact figure for the specific research product.
