What is NPY?
Neuropeptide Y is a 36-amino-acid peptide neurotransmitter involved in stress resilience, feeding, and hippocampal signaling. In neuroscience literature it is examined for anxiolytic, neuroprotective, and cognition-modulating effects.
Key Benefits & Mechanisms
stress resilience
hippocampal protection
memory modulation
anti-excitotoxic signaling
Research Summary
NPY has been shown in animal studies to protect neurons from excitotoxic injury and to dampen stress-linked cognitive impairment. It is often discussed as a counterbalance to overactive glutamatergic and stress pathways in the brain.

GPE
Glycyl-L-prolyl-L-glutamic acid
Glycyl-L-prolyl-L-glutamic acid (GPE) is a tripeptide derived from IGF-1 processing that has been studied for neuroprotection and synaptic support. It has been explored in models of learning, memory retention, and injury-related cognitive decline.

N-phenylacetyl-L-prolylglycine ethyl ester
Noopept is a peptide-derived cognitive enhancer used as a research compound and sold in some markets as a nootropic. It is studied for memory, attention, and neurotrophic signaling, especially in animal and limited human data.
Cognitive EnhancementArginine Vasopressin
8-Arginine Vasopressin
Arginine vasopressin is a naturally occurring nonapeptide hormone that also has documented CNS effects on memory and social cognition. In research settings it has been studied for its potential to influence consolidation, recall, and arousal-linked learning.
