Reconstitution / Research Dosing Reference

Quick Reference Summary

Reference Vial 20 mg Cortagen
Primary Solution Volume 1.0 mL bacteriostatic water
Primary Concentration 20 mg/mL
Measurement Reference On a U-100 syringe, 1 unit = 0.01 mL.
Amount per U-100 Unit At 20 mg/mL, 1 unit equals 0.2 mg / 200 mcg Cortagen.
Storage Reference Refrigerate at 2–8°C / 35.6–46.4°F after reconstitution, protected from direct light.

Reconstitution Steps

  1. Draw 1.0 mL bacteriostatic water using a sterile syringe for the main concentration reference shown below.
  2. Slowly add the BAC water down the side of the vial wall.
  3. Gently roll or swirl the vial until the material is completely dissolved. The solution should appear clear to slightly hazy depending on concentration and supplier format. Do not shake!
  4. Because this is a concentrated 20 mg/mL preparation, verify complete dissolution before recording final preparation details.
  5. Label with compound name, vial amount, concentration, solvent volume, preparation date, storage conditions, and handling notes.
  6. Store refrigerated at 2–8°C / 35.6–46.4°F, protected from direct light.
