Phenylethylamine

Shop on Amazon

Phenylethylamine (PEA) is used as an occasional stimulant-like nootropic, typically at 500 mg, sometimes repeated with another 500 mg for especially demanding work. It’s taken to increase dopamine signaling and sharpen mental acuity, with some people using it as a substitute for L-tyrosine or stacking it with alpha-GPC, L-tyrosine, and caffeine for a stronger focus effect.

So my particular protocol, the one I use, is I'll take phenylethylamine at dosages of about 300 to 600 milligrams along with some L-tyrosine, or I'll take it on its own with a molecule, or I should say a compound that we'll talk about a little bit later as it relates to acetylcholine alpha-GPC.
