i am a collegiate 55m and 100m sprinter myself (the 4x100 relay that i anchor just broke the school record and we are ranked 2nd in new england). i also have some experience with supplements and as far as help with sprinting supplements go, i'd say you need some.
a multi-vitamin is good for anybody. since i am an athlete, i take 2 a day, one in the morning and one after my workout to keep my body and immune system functioning properly after hard workouts.
i don't really see a need for an amino acid supplement like you listed, but rather you should invest in some good protein with a quality amino-acid profile. since Grow! and Metabolic Drive are out of stock, i recommend Optimum Nutrition 100% Whey (you can get a 10 lb. bag for $50, lasts you a few months). i take it once in the morning, once after my workout with Surge (another must have, does wonders for recovery and recuperation, provides the correct amounts of carbs and protein after a hard workout when your body most needs it, and can be purchased on the site, take only after you lift and it should last a month), and i take it once before i go to bed with milk (the casein protein in the milk digests slower) so my sleep will be more anabolic as opposed to catabolic.
creatine. preferably micronized monohydrate (the creatine on this site is perfect). creatine is associated with ATP synthesis (energy - and as an added bonus, helps with hypertrophy and strength gain, especially if you have never used it - make sure that with creatine you drink as much water as you can to avoid cramping), and in an activity like sprinting that is soley an anaerobic activity as opposed to an aerobic activity, you need all the ATP you can get. during maintenance phase i take one serving before running for energy and one serving after i lift.
Spike is also a must have for me, being in college sometimes its hard with classes, homework, etc. to find the energy and motivation to workout/run hard. Spike gives me that edge when i need it.
Glucosamine Chondroiton with MSM. not necessary, but this can be a life saver for your joints (knees, hips, ankles) after a long grueling season.
ZMA. helps with recovery, sleep, and provides you with key minerals that help muscle contractions and prevent muscle cramping. also is said to increase testosterone, thus enhance strength, but i've never really experienced that. very good and cheap ZMA on this site as well.
that's about all i can think of right now. feel free anyone to disagree with me or correct me but i think it is pretty sound advice. good luck with your track season.
