Adipotide vs P21
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.
- 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
- Estimated 2-4 hours
- Not well characterized; likely short, but neurogenic effects persist long after administration
- Admin Route
- Subcutaneous, Intravenous (research)
