Cortagen (20 mg Vial)

  • Table of Contents

Cortagen Research Chart

Cortagen has been studied in scientific research related to biological pathways and peptide mechanisms. Research findings may vary depending on study design, methodology, and experimental conditions. This information is provided for research and educational purposes only.

  • Reconstitute: Add 3.0 mL bacteriostatic water → 6.67 mg/mL (6670 mcg/mL) concentration.
  • Typical daily range: 1000–2000 mcg once daily (morning administration preferred).
  • Easy measuring: At 6.67 mg/mL, 1 unit = 0.01 mL ≈ 66.7 mcg on a U-100 insulin syringe.
  • Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); avoid freeze–thaw cycles.

Cortagen Research protocols are based on the synthetic tetrapeptide (Ala-Glu-Asp-Pro), a member of the Khavinson bioregulator class that has been studied for its neuroprotective and neuroregenerative properties. Research suggests that Cortagen may support peripheral nerve regeneration, enhance cognitive function, reduce oxidative stress in neural tissues, and promote cellular repair mechanisms when used in research settings. This educational protocol outlines a once-daily subcutaneous administration approach using a practical dilution to provide clear and consistent insulin syringe measurements.
