L-Tyrosine

“Like I think I get on really well with that. I find it's a nicer focus, not just kind of getting all jittery tyrosine, L-Tyrosine as a precursor to dopamine, Huperzine , and the cholinergic pathway. You're clearly illustrating a very important point, which is one that has been hard for me to get out”

“tend to make people feel jittery or overstimulated. Similarly, 500 milligrams to 1,000 milligrams or somewhere in between of something like L-tyrosine, which is an amino acid precursor to dopamine, a different neuromodulator, taken alone or in conjunction with, again, I believe in separating these things out by product, but I suppose you”

“experience with caffeine. And indeed, or I should say, of course, there are products out there and there are people out there that combine all three of these things together: caffeine, alpha GPC, and L-tyrosine.”

“I use L-tyrosine in capsule form. I will take 500 milligrams of L-tyrosine, 300 milligrams of alpha-GPZ, and a cup of coffee. Do this early in the day before a workout or before a bout of concentrated mental work.”

“Oh, I do. I always get asked, what should I take? I talk about alpha-GPC, L-tyrosine. I talk about theanine. I talk about theanine's use with low-dose caffeine for enhanced test switching, which is a very interesting literature.”

“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. But tyrosine and phenyl ethylamine, taken alone or together, will make you feel more motivated and more alert, more willing and able to lean into particular motivated behaviors, whether or not they're physical or cognitive.”

“seems to be a prerequisite of plasticity, which is why things like caffeine and stimulants and L-tyrosine and all these things that you can find some evidence for them improving plasticity, but it's very likely to be indirect, right?”
