Anyone tried phenylalanine & tyrosine for productivity & focus?

I have been reading some old positive reviews about these two taken on an empty focus.

So, any experiences?
Quality brands?

Thanks,

I think you mean phenethylamine which is ok but short lived

Yes, I tried both (separately and combined). I love the effects of Tyrosine - it makes me feel more focused, especially if I take a higher dosage (around 1 gram).

I bought it on Nootropics depot, but you can probably get it on Amazon and in many other stores.

Experiment a bit - you will probably like it. Just keep in mind that it's especially effective to take it prior to a stressful activity..

I hope this helps!
