Ovagen vs P21
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.
- 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); sustained gene-regulatory effects
- Not well characterized; likely short, but neurogenic effects persist long after administration
- Admin Route
- SubQ, Oral
- SubQ, Intranasal
