Noopept

Overview:
Noopept is a potent receptor site modulator and nootropic. Studies indicate its ability to increase memory and attention span, reduce worry and improve mood, and exhibit neuroprotective qualities.

Scientific Name:
N-phenylacetyl-L-prolylglycine ethyl ester

Mechanisms:

  • Racetam like properties (NMDA receptor modulator) and Ampakine like properties (AMPA glutamate receptor modulator)[1]
  • In the vicinity of 1,000 times the potency of piracetam[2]
  • Upregulates neurotrophin factors NGF and BDNF involved in neurogenesis and long term memory[3]
  • Acetylcholine and glutamate sensitizing effect[4,5]
  • Modulates EEG patterns in ways considered positive for calm alertness[1]
  • Neuroprotective effects from oxidative stress and glutamate excitotoxicity[6]
  • Anxiolytic effect – may be due to hippocampal regulation[7]
  • Cycloprolylglycine precursor – an endogenous anxiolytic neuropeptide[8]
