Peptide Calculators Hub
Access our suite of interactive calculation tools designed for laboratory research. Safely and accurately determine liquid volumes, concentrations, and drawer unit markings.
Reconstitution Calculator
Calculate units for a single peptide vial. Input vial size (mg), bacteriostatic water volume (ml), and target dose (mcg) to get syringe draw markings.
Mixing & Blend Calculator
Calculate concentrations and draw markings when blending multiple research peptides in a single reconstitution vial. Supports 2 or more compounds.

Understanding Peptide Reconstitution and Dilution Math
In laboratory research, peptides are typically supplied as lyophilized (freeze-dried) powders to ensure chemical stability. Reconstitution is the process of adding a sterile solvent—usually Bacteriostatic Water (sterile water with 0.9% benzyl alcohol)—to dissolve the powder into a liquid solution.
Core Math Formulas
Calculating target amounts requires converting between weight (milligrams and micrograms) and volume (milliliters and units). Here is the fundamental relationship:
- Mass Conversion: 1 mg = 1000 mcg
- Syringe Markings: Standard insulin syringes (U-100) have 100 units per 1 ml of volume. Thus, 1 unit = 0.01 ml.
To find the concentration of your solution in mcg per unit:
Concentration (mcg/unit) = (Total Peptide mg × 1000) ÷ (Bacteriostatic Water ml × 100)
Once you know the concentration, the syringe units required for a desired dose is calculated by:
Draw Units = Desired Dose (mcg) ÷ Concentration (mcg/unit)
Reconstitution vs. Mixing / Stacking
Reconstitution refers to preparing a single peptide vial with water. Mixing / Stacking can refer to two practices:
- Syringe Stacking: Keeping peptides separate in their respective vials, drawing Peptide A first, then Peptide B sequentially into the same syringe. This minimizes drawing steps while maintaining storage stability.
- Vial Blending: Combining two peptides into the same reconstituted vial. This requires recalculating concentrations to ensure the ratio of compounds aligns with your target dosage per volume.
