    P21: Research, Benefits & UK Availability

    A synthetic peptide derived from CNTF researched for neurogenic and nootropic properties, focusing on neurogenesis and cognitive enhancement.

    Every Peptify P21 batch is independently HPLC-tested by Janoshik Analytical (Czech Republic) and ships with the batch-matched Certificate of Analysis.

    What is P21?

    **Neurogenesis research.** P21 is the engineered CNTF-derived peptide characterised for blood-brain barrier permeability and targeted neurotrophic activity within the central nervous system — a hippocampal neurogenesis focus that distinguishes it from full-length CNTF in the published research literature.

    Research has examined neural progenitor cell proliferation in the dentate gyrus, dendritic branching, synaptic plasticity, spatial learning, and memory consolidation. Cognitive decline model work has investigated tau phosphorylation, neuroinflammation, and neuronal survival as a separate published research axis.

    10mg lyophilised vial. Batch-specific COA downloadable from the product page; 99%+ HPLC purity. For in-vitro research use only.

    Key Research Areas

    Blood-brain barrier penetrating nootropic peptide — direct access to hippocampal neurogenesis targets characterised in published research
    Neural progenitor cell proliferation in the hippocampal dentate gyrus examined — a neurogenesis-specific endpoint distinct from neuroprotection
    Dendritic branching, synaptic plasticity, and long-term potentiation studied in preclinical models as downstream outcomes of neurogenesis
    Spatial learning, memory consolidation, and cognitive performance endpoints investigated in the same models as the cellular work
    Tau phosphorylation and neuroinflammation in cognitive decline models examined — potential relevance to neurodegeneration research characterised

    How to Store P21

    Unreconstituted (Lyophilised Powder)

    Store in a cool, dry place away from direct sunlight. For long-term storage, keep refrigerated at 2–8°C. Under these conditions, lyophilised peptides can remain stable for up to 24 months. For extended preservation beyond 24 months, store at -20°C in a freezer.

    Reconstituted (Mixed with BAC Water)

    Once reconstituted with bacteriostatic water, the peptide solution must be refrigerated at 2–8°C. Use within 4–6 weeks for optimal potency. Do not freeze reconstituted peptides as this may degrade the compound.

    General Tips

    Always keep vials upright to prevent leakage. Avoid repeated temperature fluctuations — do not leave vials out at room temperature for extended periods. Protect from light exposure by storing in the original packaging or a dark container. Label all vials with the reconstitution date.

    Frequently Asked Questions

    What is P21?

    P21 is derived from Ciliary Neurotrophic Factor. It is researched for stimulating neurogenesis (new neuron growth) and enhancing cognitive function.
