Peptide Reconstitution Calculator

Peptide vials contain lyophilized (freeze-dried) powder. This form protects peptides from short term temperature changes during shipping. While powders remain stable at room temperature for a week or so, proper storage is crucial for ensuring their quality and potency.

Use our peptide calculator below to accurately prepare and dose your peptide solutions, maximizing potency and reliability for your research needs.

Peptide Vial (3ml)

2ml added (67% full)

2 ml

Bacteriostatic Water

Instructions:

  1. Add 2 ml of bacteriostatic water to your 10 mg peptide vial
  2. Gently swirl to mix (do not shake vigorously)
  3. To get 250 mcg, draw the solution to 5.0 units on your syringe
  4. Store reconstituted peptide in refrigerator and use within recommended timeframe

Storage Guidelines:

  • Powder form: Store in freezer, away from light
  • Reconstituted (mixed): Store in refrigerator

When Handling Peptides:

  • Ensure your environment is sterile
  • Clean your work surface thoroughly
  • Wash your hands properly
  • Wear sterile gloves

Reconstitution Steps:

  1. Draw bacteriostatic water into a sterile syringe
  2. Slowly inject the solvent into the peptide vial at a 45-degree angle
  3. If possible, add the solvent slowly down the side of the vial
  4. This method prevents bubble formation and ensures uniform dissolution

Storage Duration:

  • Unmixed powder: Store in freezer (-20°C)
  • Mixed solution: Up to 3 weeks at +4°C (refrigerator)
  • Long-term storage: Up to 12 months at -20°C (freezer)

Tip: Store solution in separate aliquots to minimize freeze-thaw cycles and maintain peptide quality.

Following these guidelines helps maintain peptide potency and ensures accurate results in research applications. Always consult specific peptide documentation for any special handling requirements.
