P21 10mg
BDNF-Derived Neurogenic Peptide for Cognitive Research
P21 is a peptide derived from CNTF (ciliary neurotrophic factor) that promotes neurogenesis, enhances BDNF expression, and has demonstrated significant pro-cognitive and anti-amyloid effects in animal models of neurodegenerative disease.
BDNF-Derived Neurogenic Peptide for Cognitive Research
P21 works by mimicking CNTF's neurogenic activity without its inflammatory side effects. Research in aged and Alzheimer model rodents shows enhanced neurogenesis in the hippocampus, improved cognition, and reduced amyloid-beta plaque burden.
As one of the most studied compounds in the longevity research space, P21 has attracted sustained scientific interest across Neurogenesis research, Cognitive enhancement studies, Alzheimer model research. Peer-reviewed evidence indicates that increases hippocampal neurogenesis by ~100% in aging mice, which has positioned P21 as a reference standard for researchers exploring neurogenesis research outcomes. The compound's selectivity and documented tolerability in preclinical models have contributed to a rapidly growing body of literature over the past decade.
P21 Documented Benefits: 3 Documented Mechanisms
Neurogenesis Promotion
Stimulates hippocampal neurogenesis, increasing new neuron formation in the dentate gyrus.
Cognitive Enhancement
Improves spatial memory, learning, and cognition in aged and Alzheimer model animals.
Amyloid Reduction
Reduces Aβ plaque load and tau pathology in preclinical Alzheimer research.
How P21 Works: Molecular Mechanism & Pathway
CNTF-derived tetrapeptide activating STAT3 and BDNF-related neurogenic signaling pathways without the inflammatory CNTF receptor effects.
The 3 primary research pathways identified for P21 — Neurogenesis Promotion, Cognitive Enhancement, Amyloid Reduction — collectively point to a compound with pleiotropic activity across interconnected biological systems. Studies have further shown that improves cognition in Alzheimer model rodents, reinforcing the mechanistic picture established in earlier cell-line work. Unlike single-pathway agents, P21's broad receptor engagement profile continues to generate hypotheses for novel applications beyond its originally characterized use cases.
Research Protocols & Compound Combinations
P21 is routinely studied alongside NAD+ and Semax in longevity-focused compound panels. Researchers investigating neurogenesis research have found that pairing compounds with complementary receptor profiles can produce additive results while keeping individual doses within well-characterized ranges. Preliminary evidence that reduces amyloid beta and tau markers has informed several of these multi-compound protocol designs.
Purity, Testing & Research Grade Standards
All P21 research material offered through this catalog is manufactured under controlled conditions and independently verified by a third-party laboratory prior to release. Each lot undergoes High-Performance Liquid Chromatography (HPLC) analysis to confirm ≥98% purity, with identity confirmed via mass spectrometry. The accompanying Certificate of Analysis (CoA) documents the exact purity, molecular weight confirmation, and lot-specific testing date — data that should accompany any reproducible research protocol. Lyophilized powder formulation ensures maximum stability during shipping and storage at −20°C long-term or 4°C for short-term use.
