The reason for my consumption of this cheap amino acid (about 10.00 per 100 capsules at the GNC), is for my attention. After about a month of being off of my Adderall xr 15mg, my grades crashed and burned. I was losing complete focus on day to day activities, and as for my impulsivity, lets just say that I had regressed in maturity to that of a 5-year old. Let us begin the very uncontrolled study that I performed over the course of a week:

Day1:
L-Tyrosine, 500mg on empty stomach
-No significant differences in the way I feel (mood)
Since this is not a school day, I have not attempted to concentrate on anything, and therefore do not yet know the extent to which this affects my attention-span.

Day2:
L-Tyrosine, 500mg and Vivarin (caffiene, 200mg)
-Feeling much more talketive, and energetic. Probably just the caffiene pill.

Day3:
L-Tyrosine, 1000mg on empty stomach
-Feeling a calmness about me. Very mild euphoria, similar to a very low oral dose of amphetamine. Perhaps the amino acid must build up in my system.
P.S. No appetite

Day4:
L-Tyrosine, 1000mg; AdderallXR 15mg on empty stomach
-VERY calm. The calmness is quite overbearing, feels like my body wants to sleep, but my mind wont let me. Probably the effect it has on my hyperactivity, and ability to increase alertness.
P.S. Negative appetite. I couldnt eat if I wanted to. lol

Overall Eveluation: Found slight increase in attention span, not nearly as potent as amphetamines (no shit). Feels much more natural than the 'forced concentration' that Adderall seems to give me. Feel much less controlled by a drug. Its a fantastic way to cut down on the appetite. Overall I think this is a good choice for enhancing alertness, and concentration, but not AS effective as adderall.
