How to Reconstitute Peptides

Reconstitution is the process of adding bacteriostatic water (BAC water) to a lyophilized (freeze-dried) peptide powder to create an injectable solution. Getting the right concentration is critical for accurate dosing.

Step-by-Step Process

  1. Clean the vial tops with an alcohol swab and let dry
  2. Draw bacteriostatic water into a syringe (the amount calculated above)
  3. Inject slowly down the side of the peptide vial — never spray directly onto the powder
  4. Gently swirl the vial until the powder dissolves — do not shake
  5. Store refrigerated at 36-46°F (2-8°C) after reconstitution

Important Safety Notes

  • Always use bacteriostatic water (BAC water), not sterile water, for multi-dose vials
  • Reconstituted peptides are typically stable for 28-30 days refrigerated
  • Use insulin syringes (U-100) for accurate measurement
  • Consult with a healthcare provider before using any peptide therapy
