Peptide Dosing Calculator

The Peptide Dosing Calculator estimates Syringe Units per Dose based on body weight, desired dosage, and peptide concentration. This calculator helps fitness enthusiasts and researchers ensure accurate administration by converting complex measurements into simple injection volumes. Whether you're starting a new peptide protocol, adjusting your solution concentration, or managing multiple daily doses, this tool provides precise calculations to eliminate guesswork.

How Syringe Units per Dose Is Calculated

Syringe Units per Dose represents the specific amount of liquid you need to draw into your syringe to achieve the correct dosage. This calculation uses a standard medical conversion method to translate weight-based prescriptions into practical measurements.

Syringe Units = (Weight (kg) × Dosage (mcg/kg)) ÷ (Concentration (mg/ml) × 10)

Where:

  • Weight (kg) = Your body mass in kilograms
  • Dosage (mcg/kg) = Desired micrograms per kilogram
  • Concentration (mg/ml) = Strength of your mixed solution
  • 10 = Constant converting milligrams to units

First, the tool converts your weight to kilograms and calculates the total dosage in micrograms. Then, it divides the total dosage by the concentration to find the required liquid volume in milliliters. Finally, the volume is multiplied by 100 to convert it into units for a standard U-100 insulin syringe. This method ensures you draw the exact amount needed for each administration.

What Your Syringe Units per Dose Means

Your result indicates the exact mark on the syringe barrel you must draw to reach your target dosage. This number simplifies complex math into a single, actionable measurement for safe injection.

  • Recovery Protocols: For low-dose regimens like BPC-157, your result often falls between 5 and 15 units. This range is typical for daily maintenance and healing support.
  • Performance Protocols: Higher dosages, often used for growth hormone secretagogues, might yield results between 20 and 50 units. You may need a larger syringe size to accommodate these volumes comfortably.
  • Micro-dosing: If you are sensitive to peptides, your calculated amount might be very small, often under 5 units. This requires a high level of precision and a steady hand during administration.

Pro Tip

Always double-check your syringe type. Insulin syringes are usually U-100 (100 units per ml), but other types exist. This tool assumes you are using a standard U-100 syringe for the most accurate conversion.
