as far as feeling different, when the gear kicks in, you may get occasional insomnia (which is easily fixed with melatonin, diphenhydramine hcl, or other sleep-aid).
you may get increased anxiety, but it's not like a "i've had too much caffiene and am now jittery" anxiety. it's more of an energetic kind of anxiousness.
your sex drive will most likely shoot through the roof. this is one of the side-effects that most people look forward to of course.
some people get increased aggression, which if you do, hopefully you can keep it in the gym during your workouts where it belongs. then again, that's just like drinking alcohol, some people drink and get happy, others get violent. it all depends on the person.
not everyone will get all the symptoms (though most will experience the increased sex drive), and some symptoms may happen as the gear kicks in and fade as your body adapts.
overall, the negative side-effects are usually well within tolerable limits and the benefits well outweight them. as far as it negatively affecting your sports, if it did that, then why do all the pro athletes use gear? the only way gear would negatively affect your sports is if you focus more on your anaerobic training (weights) and less on your aerobic (cardio). then you will get increased strength, but at the cost of endurance.
before starting test however, i'd suggest doing plenty of research, as it can greatly help you create a more effective and safer cycle for yourself. good luck.
