While I agree with you and have used PEA and related amino acids with good effect for years, it is worth remembering that to convert PEA to the body's natural methamphetamine--methylphenethylamine--you need solid methylation ability.
People who have a mercury or cadmium problem will likely be somewhat lacking in that area. Also people with low B12, folate, choline, zinc may as well.
Also to get phenylalanine or tyrosine to convert down to dopamine we need a number of cofactors such as iron, B & C vitamins.
People who have a history of panic attacks or very intense, angry outbursts probably should not mess with catecholamine support until they have more stable health.
For some of the above, you might look for low lithium in your hair test--more on that if requested. There can be many other factors--high copper, need for support for liver, adrenal cortex, magnesium, etc.
