The math. Not the dose.

Vial mass + BAC water volume → concentration. Concentration + desired draw → volume. Same equation works for every compound, every vial size. We do not provide dosing or administration guidance.

Gloved hands drawing bacteriostatic water from a 10 ml Optimal Lab vial into a 1 ml syringe, with a smaller lyophilised peptide vial held alongside.

The equation

Concentration (µg/mL) = vial_mass (µg) ÷ water_volume (mL)
Draw_volume (mL) = research_amount (µg) ÷ concentration (µg/mL)
