P21

P21 is a small synthetic peptide derived from CNTF (ciliary neurotrophic factor), the protein responsible for neuron survival — modified with an adamantane moiety so it crosses the blood-brain barrier. In animal models it raises BDNF, drives neurogenesis in the hippocampal memory center, rebuilds synapses, and reduces tau tangles in Alzheimer's models.

It remains one of the least talked-about brain peptides in research circles: there is zero published human data, and the research record comes entirely from cell and animal studies. Every lot is third-party tested for identity and purity, with certificates of analysis available on request. Vials arrive sealed and sterile, lyophilized for stability, and ship from our U.S. facility.

For in vitro laboratory research use only. See the Technical Data tab below for the full mechanism and feature summary.
