P21 (also known as Peptide 021) is a synthetic tetrapeptide derived from a four amino acid active sequence of ciliary neurotrophic factor (CNTF), modified with an adamantane group to enhance lipophilicity and blood brain barrier penetration. Hudson Science’s formulation supplies 10mg as a lyophilized vial, preserving peptide structural integrity across storage conditions until reconstitution. The adamantane modification requiring intact peptide structure to maintain its intended CNS delivery advantage.
CNTF is a neurotrophic factor with documented roles in neuronal survival and neurogenesis signaling, but its native form faces significant limitations as a research tool due to poor blood brain barrier penetration and a short half-life. P21’s design addresses this directly by isolating the active four amino acid CNTF sequence responsible for receptor mediated signaling and attaching the same adamantane lipophilic modification used in Adamax’s Semax analogue design, P21 is engineered to access central nervous system tissue more effectively than native CNTF while mimicking CNTF receptor mediated signaling activity.
P21’s research profile centers on preclinical investigation into hippocampal neurogenesis promotion, reduction of amyloid and tau pathology in rodent and cell culture models, and cognitive recovery research relevant to neurodegenerative conditions including Alzheimer’s disease and age related cognitive decline. It is important to note that P21’s research evidence base is currently limited to preclinical rodent and cell culture studies. No human clinical trials or regulatory approvals exist for this compound, and comprehensive human safety, toxicity, and pharmacokinetic data are not established in peer reviewed literature at this time.
Hudson Science formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks P21 alongside Adamax, Semax, and Pinealon in the neuroprotective and cognitive research peptide range, giving researchers access to multiple CNS targeted compounds from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Reconstitute with bacteriostatic water prior to use. Store lyophilized peptide at 2–8°C away from direct light. Once reconstituted refrigerate and use within 28 days. Intended for research purposes only.
