Description
P21 Peptide Spray provides a small, brain-penetrant peptide derived from ciliary neurotrophic factor in a ready-to-use bottle. Limitless Life Nootropics offers it in 25mg and 50mg sizes, made in the USA.
What Is P21 Peptide Spray?
Ciliary neurotrophic factor (CNTF) is a large protein that supports neuron survival, but its size limits its usefulness in research on the living brain. Scientists at the New York State Institute for Basic Research identified a short active region (residues 148-151) and created a peptide mimetic based on it, known as P021.
An adamantylated glycine was added to the C-terminus to increase lipophilicity and stability. In mouse models of Alzheimer’s disease and aging, the compound was reported to increase neurogenesis in the hippocampus, reduce tau pathology and improve performance in memory tasks.
Available in 25mg and 50mg bottles, Non-Lyophilized grade.
Key Research Areas
The scientific literature describes this spray across several areas of investigation:
- Hippocampal neurogenesis
- Tau and amyloid pathology models
- Synaptic plasticity markers
- Memory performance in aged mice
- BDNF expression
Researchers can review peer-reviewed studies on P021 through the National Library of Medicine (PubMed) database.
