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

Thymagen effects

  • Reported improvement in T-cell function and number
  • Support of thymic function in aging populations
  • Recovery support after severe illness
  • Anti-inflammatory effects
  • Modulation of immune gene expression

Bronchogen side effects

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

Thymagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Caution in active autoimmune disease

Bronchogen dosing ranges

Bronchogen vs Thymagen — common questions

What is the difference between Bronchogen and Thymagen?

Bronchogen: Khavinson short peptide bioregulator targeting bronchial epithelium and lung tissue. Typical dose 1,000-5,000 mcg. Thymagen: Khavinson short peptide bioregulator targeting thymic function — Glu-Trp synthetic version. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Bronchogen and Thymagen?

Stacking Bronchogen with Thymagen 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 Thymagen?

Bronchogen is typically dosed: Once daily (SubQ) or sublingual for Bronchial function support. Thymagen is typically dosed: Once daily (SubQ) or sublingual for Immune support.

Are Bronchogen and Thymagen FDA approved?

Bronchogen: Not FDA approved. Thymagen: Not FDA approved.
