    What Is P21 10mg?

    P21 10mg Vial Overview

    P21 is an 11-mer peptide derived from ciliary neurotrophic factor (CNTF) that promotes hippocampal neurogenesis without appetite-suppressing side effects. In Alzheimer's models, it rescued cognitive deficits, increased neurogenesis, reduced tau hyperphosphorylation, and decreased neuroinflammation.
