I tried amphetamine salts (w/ a prescription) at one point. They make you SUPER concentrated. They worked for me until I built a tolerance up, but that's only because I don't suffer from anxiety about my T, just depression.
I'd say if you're SUPER ANXIOUS about T, constantly checking it every 2 seconds, you probably wouldn't get much out of it as it raises your awareness of stimuli and, as a dual action, stimulates your nervous system, sharpening your senses - it can very well raise the volume of T, temporarily.
But don't take my word for it; the only way to really know is to try it. Like glynis said, talk to your doc. If you DO try it and DO enjoy it, please do not abuse it, it is highly addictive and can be very dangerous in general for off-label (read ADHD) uses.
