Pinealon vs P21
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
- 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 (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Not well characterized; likely short, but neurogenic effects persist long after administration
