Phenylethylamine HCL

PEA is an endogenous neurotransmitter and neuroregulator that plays a key role in mood and cognition. It is associated with states of heightened arousal, euphoria, and excitation, as well as increased attention and concentration.

Scientific Name:
Phenylethylamine, (PEA)


  • Stimulates dopamine, norepinephrine, and acetylcholine levels[1]
  • Modulates receptor sensitivity and reuptake processes[1]
  • Synthesized in the body from the amino acid phenylalanine[2]
  • Psychoactive ingredient in chocolate and blue green algae[3,4]
  • Synergistic with MAO-B inhibitors like Hordenine[5]
  • Phenylethylamines are a category of empathogens and entheogens derived from PEA and that act largely on its receptor sites[1]
