Peptide Calculation Guides
Reference explanations of the arithmetic behind reconstitution — concentration, unit conversion and syringe readings — written to be verifiable by hand.
How to Use a Peptide Reconstitution Calculator
A peptide reconstitution calculator converts three user-supplied values — vial amount, added liquid volume and target research amount — into a concentration, a dose volume in millilitres and the equivalent U-100 syringe units.
How Peptide Reconstitution Calculations Work
Reconstitution maths normalises every input to a single mass unit, divides mass by volume to get concentration, then divides the target amount by that concentration to get a volume that is finally scaled to syringe units.
mg vs mcg: Converting Peptide Amounts
One milligram equals 1000 micrograms, so mg → mcg multiplies by 1000 and mcg → mg divides by 1000.
mL to Units on a U-100 Syringe
On a U-100 syringe, 1 mL equals 100 units, so units = mL × 100 and mL = units ÷ 100.
Calculating Peptide Concentration
Peptide concentration is the labelled vial amount divided by the volume of liquid added: concentration (mg/mL) = mg ÷ mL.
Calculating How Much Bacteriostatic Water to Add
To reach a chosen concentration, divide the vial amount by that concentration: diluent volume (mL) = vial amount (mg) ÷ target concentration (mg/mL).
Run the numbers
Once the maths makes sense, the peptide reconstitution calculator applies it to your own values, and the peptide library holds reference information on individual compounds.
