I love how we're bumping 5 month old threads, don't you? Anyways, caffeine is cheap enough on the net that it would be worth your while to buy it pure.

Hi, I just suggest to get the stuff online and just use that...Always its better to be quick in handling things rather than doing experiments... cheers, suma ------------------------------------ http://www.coffeebreakusa.com/
