Cortagen (20 mg Vial) Dosage Protocol
Cortagen Dosage Chart
Cortagen is dosed at 1 mg–2 mg daily via subcutaneous injection in educational protocols. A 20 mg vial reconstituted with bacteriostatic water yields about 6.67 mg/mL. This information is for research and educational use 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 dosage protocols are designed around this synthetic tetrapeptide (Ala-Glu-Asp-Pro) that belongs to the Khavinson bioregulator class, studied for its neuroprotective and neuroregenerative properties[1][2]. Research indicates Cortagen may support peripheral nerve regeneration, enhance cognitive function, reduce oxidative stress in neural tissues, and promote cellular repair mechanisms without significant adverse effects at therapeutic doses[3][4]. This educational protocol presents a once-daily subcutaneous approach using a practical dilution for clear insulin-syringe measurements.
Research context: For evidence on mechanisms, human and preclinical research, limitations, and safety, read Cortagen Peptide: Benefits, Uses, Side Effects, Dosage, and Research.
Standard Approach (3 mL = 6.67 mg/mL)
Weeks 1–2
1000 mcg
15 units (0.15 mL)
Weeks 3–4
2000 mcg
30 units (0.30 mL)
Frequency: Inject once daily subcutaneously, preferably in the morning[5]. This schedule uses the largest practical dilution (3.0 mL) to keep per-injection units ≥15 for accurate measurement. For doses under ~10 units (<700 mcg), consider using 50-unit or 30-unit insulin syringes for improved readability.
Reconstitution Steps
Draw 3.0 mL bacteriostatic water with a sterile syringe.
Inject slowly down the vial wall; avoid foaming.
Gently swirl/roll until dissolved (do not shake).
Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
Supplies Needed
Plan based on a 4-week daily protocol with gradual titration (1000–2000 mcg/day).
Peptide Vials (Cortagen, 20 mg each):
4 weeks ≈ 3 vials (at average 1500 mcg/day = 42 mg total)
8 weeks ≈ 5 vials
Insulin Syringes (U-100):
Per week: 7 syringes (1/day)
4 weeks: 28 syringes
8 weeks: 56 syringes
Bacteriostatic Water (10 mL bottles): Use 3.0 mL per vial for reconstitution.
4 weeks (3 vials): 9 mL → 1 × 10 mL bottle
8 weeks (5 vials): 15 mL → 2 × 10 mL bottles
Alcohol Swabs: One for the vial stopper + one for the injection site each day.
Per week: 14 swabs (2/day)
4 weeks: 56 swabs → recommend 1 × 100-count box
8 weeks: 112 swabs → recommend 2 × 100-count boxes
