P21 5 mg
P21 5 mg – Peptide Hubs P21 is a synthetic nootropic peptide originally developed to enhance memory, learning, and neurogenesis in preclinical models of brain injury and cognitive decline. It is based on a modified segment of the CNTF (ciliary neurotrophic factor) and penetratin peptide to facilitate blood-brain barrier transport and receptor binding. Peptide Hubs offers P21 in 5 mg high-purity lyophilized form for research use only. Mechanism of Action P21 appears to promote neurogenesis, neurotrophic signaling, and synaptic plasticity by enhancing expression of proteins like GAP-43 and BDNF. It also shows potential to regenerate neuronal architecture in animal models of cognitive injury, particularly in aging or chemically-induced brain damage. This review on peptide nootropics discusses emerging candidates like P21 in neurodegeneration and trauma. Research Applications Memory enhancement and cognitive performance studies Brain injury and regeneration models Alzheimer's and neurodegenerative disorder protocols Long-term potentiation and synaptogenesis investigations P21 is often paired with N-Acetyl Semax Amidate or N-Acetyl Selank Amidate in emotional memory and neuroplasticity studies. For mitochondrial synergy, researchers combine it with Humanin or MOTS-c. DNA repair models frequently include FOX04-DRI in stacked protocols for cellular senescence and neuroprotection.
Oxytocin 10 mg
Oxytocin 10 mg – Peptide Hubs Oxytocin is a naturally occurring neuropeptide and hormone produced in the hypothalamus and secreted by the posterior pituitary. It plays a key role in regulating social bonding, empathy, stress modulation, emotional connection, and trust behaviors. Peptide Hubs offers Oxytocin 10 mg in high-purity lyophilized form for scientific research exploring psychoneuroendocrinology and behavior. Mechanism of Action Oxytocin interacts with its specific G-protein-coupled receptor (OXTR), highly expressed in the brain, heart, and reproductive organs. Its activation influences emotional processing centers including the amygdala and hypothalamus, impacting fear, bonding, and social memory. Additionally, oxytocin modulates stress by attenuating cortisol levels. Learn more from this NIH review on oxytocin and social cognition. Primary Research Applications Studies on social bonding, trust, and empathy Neuropsychiatric disorder models: PTSD, anxiety, autism Cortisol modulation and stress resilience research Reproductive and lactation-related investigations In modern psychoneuroendocrinology models, oxytocin is often stacked with DSIP to study circadian influences on social behavior, or with N-Acetyl Selank Amidate for anxiety and emotional reactivity protocols. It may also be paired with Humanin to investigate age-related declines in bonding and cognitive empathy. For metabolism-affecting studies, researchers may include Semaglutide.
P21 5 mg
Dragon Pharma P21 5 mg – Synthetic CNTF-Derived Peptide for Neurogenesis Research ✔ Synthetic lipophilic tetrapeptide ✔ Derived from ciliary neurotrophic factor (CNTF) ✔ Blood-brain barrier penetrant ✔ USA domestic shipping available Dragon Pharma P21 5 mg is a synthetic, lipophilic tetrapeptide derived from ciliary neurotrophic factor (CNTF). This compound, also known as P021, has been designed to cross the blood-brain barrier and is studied in preclinical models for its potential to promote neurogenesis, increase brain-derived neurotrophic factor (BDNF) levels, and support synaptic plasticity in the context of neurodegenerative conditions such as Alzheimer's disease. Each vial contains 5 mg of lyophilized P21 in a 2 mL format, requiring reconstitution with bacteriostatic water before use.

P21 represents a focused approach to studying neurotrophic signaling and neurogenesis. By mimicking key functional domains of CNTF while maintaining a small, lipophilic structure, this peptide offers improved CNS bioavailability compared to larger neurotrophic factors. Its ability to enhance BDNF expression and support synaptic plasticity provides researchers with a tool to investigate the molecular pathways underlying learning, memory, and neural repair. Researchers value P21 for its targeted mechanism and practical research applications. Its small size and blood-brain barrier penetration capabilities make it suitable for various experimental designs, from in vitro neuronal culture studies to in vivo models of cognitive function and neurodegeneration.
