Reference Information
Understanding Reconstitution Math
Concentration Formula
Concentration (mg/mL) = Peptide Amount (mg) ÷ Water Volume (mL). For example, 10 mg of peptide reconstituted in 2 mL of bacteriostatic water yields a concentration of 5 mg/mL.
Syringe Unit Conversion
Standard insulin syringes are marked in “units.” A 1 mL syringe has 100 units, a 0.5 mL syringe has 50 units, and a 0.3 mL syringe has 30 units. Each unit equals 0.01 mL regardless of syringe size.
Aliquots Per Vial
Total aliquots = Total Peptide (mcg) ÷ Desired Amount (mcg). This tells you how many equal measurements can be obtained from a single vial at the selected amount.
Glossary
Key Terms
Lyophilized Peptide
A freeze-dried peptide powder, stored in a sealed vial prior to reconstitution.
Bacteriostatic Water
Sterile water containing 0.9% benzyl alcohol as a preservative, commonly used for reconstitution.
Reconstitution
The process of adding a solvent (e.g. bacteriostatic water) to a lyophilized compound to return it to solution.
Concentration (mg/mL)
The amount of peptide per milliliter of solution after reconstitution.
mcg (Microgram)
One millionth of a gram (1/1000 of a milligram). A common unit for measuring peptide amounts.
IU / Units
Markings on insulin syringes. 100 units = 1 mL. Used to measure small volumes accurately.
