How This Works

Promotes Hippocampal Neurogenesis

The hippocampus is the core brain region responsible for learning and memory. P21 facilitates the generation of new neurons in the hippocampus, enhances synaptic plasticity, strengthens signal transmission between neurons, and supports memory formation and learning capacity.

Suppresses Neuroinflammation & Provides Antioxidant Protection

Inhibits excessive activation of microglia to reduce chronic neuroinflammation in the brain; alleviates oxidative stress, stabilizes mitochondrial function and lowers neuronal apoptosis.

Items Specifications

P21 5mg*10vials
Potential Benefits

Supports Memory and Learning Ability

Promotes hippocampal neurogenesis and enhances synaptic plasticity, facilitating memory consolidation and information learning.

Neuroprotective Effects

Possesses antioxidant properties, inhibits chronic brain inflammation, stabilizes mitochondria and reduces neuronal damage and apoptosis.

Combats Neurodegenerative-Related Damage (Preclinical Research)

Inhibits tau hyperphosphorylation and alleviates cytotoxic damage to neurons.

Capable of Crossing the Blood-Brain Barrier

Modified small-molecule structure, which can effectively enter brain tissue to exert effects, unlike native CNTF.

Lower Risk of Side Effects

Engineered CNTF mimetic peptide, avoiding common adverse reactions of full-length CNTF such as appetite suppression.
