Bronchogen
Summary
Somatropin is recombinant human growth hormone (rhGH), identical in structure to the 191-amino acid pituitary-derived growth hormone. It is FDA-approved for growth hormone deficiency, short stature, and wasting conditions. Off-label, it is widely explored for body composition, anti-aging, and performance enhancement, though significant risks accompany unsupervised use.
Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
Half-Life
2-3 hours (subcutaneous); 20-30 minutes (intravenous)
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
Admin Route
Subcutaneous, Intramuscular (less common)
SubQ, Oral
Research
Typical Dose
0.15-0.3 mg/day (adults); titrated to IGF-1 levels
10 mg per day
Frequency
Once daily
Daily for 10–30 days
