Basic in the fasting combo
If you are looking for more vitality, a greater cognitive focus and tunnel effect, it seems to me a basic product combined with caffeine extended release for before a workout fasting at a dose of one or two capsules is a very good combo, topped with creatine and get very good results.

L-TYROSINE 500mg
Good, but with caution
I bought it for a time of exams, when I needed to be more alert and sharp in the head. I do notice its effect, but it is also true that I notice that it aggravates a bit the anxiety I already have, so I take it in spurts and with caution. Also, since I have melasma, I don't take it often just in case. I would recommend it for occasional moments.

L-TYROSINE 500mg
Expensive but useful
Fairly expensive ingredient. I used it as a pre-workout along with caffeine to better tolerate the effects of the latter.

L-TYROSINE 500mg
Perfect
It is quite good to take as a pre-workout, as it has no flavor it is a bit bitter but in my point of view it is easy to take. Also mixed with any other flavored product I don't notice it, I think it's good.
