What is Peptide Dosage & Reconstitution?

  • Definition of Peptide Dosage
  • Why Reconstitution is Important
  • Units: mg vs IU
Peptide dosage refers to the precise amount of peptide administered to achieve a desired biological effect. Reconstitution is the process of mixing a lyophilized (freeze-dried) peptide with a solvent, usually bacteriostatic water, to prepare it for injection.
Understanding Units: mg and IU

Unit Examples

  • A 10 mg vial reconstituted with 2 ml solvent gives a concentration of 5 mg/ml.
  • A 100 IU vial reconstituted with 2 ml solvent gives 50 IU/ml.

Step-by-Step Guide to Using the Calculator

  • Input Your Body Weight
  • Select Dose per kg and Unit
  • Enter Vial and Solvent Details
Start by entering your body weight in kilograms. Next, specify the dose per kg and select the appropriate unit (mg or IU). Enter the total peptide in the vial and the amount of solvent added. Optionally, set injections per day and cycle length.
Using the Calculator Effectively

Step-by-Step Examples

  • For a 75 kg person at 0.1 mg/kg, the daily dose is 7.5 mg.
  • For 2 injections per day, each injection is half the daily dose.

Real-World Applications of Peptide Dosage Calculators

  • Bodybuilding and Fitness
  • Medical and Research Use
  • Safe Home Preparation
Peptide dosage calculators are used by athletes, researchers, and clinicians to ensure accurate dosing, minimize waste, and maximize safety. They help avoid under- or overdosing and ensure consistent results.
Practical Use Cases

Application Examples

  • A bodybuilder uses the calculator to split a 30-day cycle into daily injections.
  • A researcher prepares multiple vials for a study, ensuring each has the correct concentration.

Common Misconceptions and Correct Methods

  • Mixing Errors
  • Unit Confusion
  • Injection Volume Mistakes
Many users confuse mg and IU, or miscalculate injection volumes. Always match units and double-check calculations. Use the calculator to avoid common mistakes.
Avoiding Errors

Misconception Examples

  • Entering IU when the vial is labeled in mg leads to incorrect dosing.
  • Not accounting for solvent volume results in wrong injection amounts.

Mathematical Derivation and Examples

  • Dosage Formula
  • Concentration Calculation
  • Injection Volume Formula
Total daily dose = body weight × dose per kg. Solution concentration = total peptide / solvent volume. Injection volume = dose per injection / concentration.
Worked Examples

Math Examples

  • 75 kg × 0.1 mg/kg = 7.5 mg daily dose.
  • 7.5 mg / 5 mg/ml = 1.5 ml injection volume.
