There aren't many products that will increase pure speed per se. KR10 Creatine can will help maintain speed over repeated intervals, e.g. for 10 short sprints it is unlikely the first few would be any faster after creatine loading but you would notice a difference in the last few.

Similarly using GO>>> electrolyte or PSP22 energy can help maintain speed over repeated intervals of a longer duration, and is certainly useful during speed training.

Speed is a product of power to weight so it may be a good idea to reduce your mass if speed is your current limiting factor.

If your carrying extra weight reducing Fat Mass is the next thing that you should try and CLA supplements could help with this and there is some evidence that taking a protein supplement like SiS BUILD 30-60 mins prior to a meal will help you to reduce your calorie consumption at meal times.

If you are training hard we have some evidence that taking Nocté 30-60 minutes before bed can help reduce waking muscle soreness and maintain testosterone levels;- both these things should help you go faster.

You could also experiment with the new Smart-1 energy gels - these are based on the award winning GO Gels with added caffeine and phytonutrients to help improve blood flow;- they will certainly pick you up at half time or other appropriate interval.
