Chonluten vs P21

Side-by-side comparison of key properties, dosing, and research.

Summary
Chonluten is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, tissue-specific to the bronchi and lungs. While related to Bronchogen (a tetrapeptide), Chonluten is a shorter tripeptide sequence. It supports bronchial mucosal cell function, promotes respiratory epithelial regeneration, and is used in protocols for COPD, chronic bronchitis, and pulmonary anti-aging.
P21 is a synthetic peptide derived from CNTF (ciliary neurotrophic factor) that promotes hippocampal neurogenesis, enhances memory and spatial learning, and may reduce amyloid-beta pathology. It is used as a neurogenic and cognitive enhancer with potential anti-Alzheimer's applications.
Half-Life
Short (minutes for the peptide); sustained gene-regulatory effects
Not well characterized; likely short, but neurogenic effects persist long after administration
Admin Route
SubQ, Oral
SubQ, Intranasal
