Bronchogen effects

  • Reported restoration of bronchial epithelial function
  • Improvement in pulmonary function tests (Russian observational data)
  • Reduction in COPD/bronchitis exacerbation frequency
  • Improved dyspnea and exercise tolerance
  • Anti-inflammatory effects in bronchial tissue

Cortagen effects

  • Reported support of cortical neuron function and gene expression
  • Improvements in memory and attention (Russian observational)
  • Neuroprotection in cerebral ischemia models
  • Possible support for post-stroke and post-concussive recovery
  • Modulation of neuroplasticity-related gene expression

Bronchogen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Occasional allergic reactions (rare)
  • Limited Western safety validation

Cortagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Possible mild sleep disturbance with late-day dosing

Bronchogen dosing ranges

Bronchial function support

1-5 mg · Once daily (SubQ) or sublingual · 10-20 day cycles, repeated 2-3 times per year

Cortagen dosing ranges

Cognitive support

1-5 mg · Once daily morning (SubQ) or intranasal · 10-20 day cycles, repeated 2-3 times per year

Bronchogen vs Cortagen — common questions

What is the difference between Bronchogen and Cortagen?

Bronchogen: Khavinson short peptide bioregulator targeting bronchial epithelium and lung tissue. Typical dose 1,000-5,000 mcg. Cortagen: Khavinson short peptide bioregulator targeting cortical neurons and CNS gene expression. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Bronchogen and Cortagen?

Stacking Bronchogen with Cortagen is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.

Which is dosed more frequently, Bronchogen or Cortagen?

Bronchogen is typically dosed: Once daily (SubQ) or sublingual for Bronchial function support. Cortagen is typically dosed: Once daily morning (SubQ) or intranasal for Cognitive support.

Are Bronchogen and Cortagen FDA approved?

Bronchogen: Not FDA approved. Cortagen: Not FDA approved.
