What Is Cortagen Peptide?

Cortagen is a proprietary peptide formulation that typically combines multiple stress-modulating peptides to target various aspects of HPA axis function and stress adaptation. While exact formulations may vary, Cortagen often includes:

1. ACTH (Adrenocorticotropic Hormone) fragments – Regulate cortisol production
2. Vasopressin analogs – Modulate stress responses and water balance
3. Neuroprotective peptides – Protect against stress-induced neuronal damage
4. Cognitive-enhancing peptides – Improve memory and focus under stress
5. Antioxidant peptides – Reduce oxidative stress from chronic stress

Key Features of Cortagen:

✅ HPA axis modulation – Optimizes cortisol levels for healthy stress responses
✅ Stress adaptation – Enhances resilience to acute and chronic stress
✅ Neuroprotection – Protects neurons from stress-induced damage
✅ Cognitive enhancement – Improves memory, focus, and mental clarity
✅ Anti-inflammatory effects – Reduces stress-related inflammation
✅ Metabolic optimization – Balances energy metabolism during stress

Cortagen Peptide Dosage Protocols for Research

Since Cortagen is not approved for human use, dosage guidelines are based on preclinical and research models. Researchers should adjust protocols based on study objectives.

General Dosage Guidelines

Key Dosage Considerations

✔ Start with lower doses (100-200 mcg/kg) to assess tolerance and efficacy
✔ Monitor cortisol levels and stress biomarkers throughout the study
✔ Adjust administration route based on study objectives (e.g., intranasal for cognitive effects, SC for systemic effects)
✔ Combine with behavioral interventions (e.g., stress management techniques) for enhanced effects
✔ Cycle Cortagen to prevent tolerance and maintain efficacy
