Thank you very much WMD, you have given me more information in your last reply than I have had from other sites (I mainly meant this site gives more valuable advise and have users that can help from thier own experience)
I have recently bought "The Optimum Nutrition Bible" so i can get a better understanding myself about Nutrition and what happens inside.
I will finish the PhD I have already bought (should last a month) and then look at thos you have recommended.
Thanks Again
