powders gram for gram are the cheapest. go and fine the most inexpensive whey powder u can find and it will not be that much. around where i am at gnc makes the cheapest. whey protein is pretty much all the same.
people will give you one hundred different opinions tho. i found a personal trainer and paid him to teach me for about 2 months; it wasnt cheap, but it made me get fitter faster cuz someone that was a professional was teaching me.....
i use whey and eat a lot of scrambled eggs (1 yolk w/5-6 whites), tuna is ok, chicken. i use met-rx bars every now and then just to break up the monotony.
online is usually cheapest if u google and price.
might i suggest a forum for this type stuff? where weightlifters/bodybuilders/power types go.
hope this helps,
