I didn't know that there were so big differences, depending where you buy. I know that knowledge is key, but I don't think that mentioning the level of caffeine will really refrain many people from buying... It's not only about information. See smokers for instance, do you think that they lack information? Many medical studies show that caffeine is great in moderation for adults: http://ephedrinewheretobuy.com/ephedrine-where-to-buy-eca-stacks/coffee-a-true-wonder-drug But in moderation only; for caffeine as for most natural products, a little is a health-promoter, a lot is a health-negative: sleep disorders, nervousness, irritability, stomach upset, fast heartbeat etc... My recommendation: don't worry about coffee if you have a moderate consumption :)
