50mg caffeine plus 90egcg=4% 200mg caffeine plus 360 egcg=?

Have any studies been done combining egcg with more caffeine? Comparing green tea to ephedrine isn't quite fair when studies are done with 50mg caffeine, could similar effects be seen with a rise in caffeine? Also any guesses to an upper limit of effectiveness for a 100kg man combining green tea, yohimbine hcl, and caffeine?

green tea is completely different than ephedrine and cant really be compared.

It isnt the caffeine in green tea which results in the fat loss (see - Efficacy of a green tea extract rich in catec... [Am J Clin Nutr. 1999] - PubMed - NCBI), it is the catechin amount. catechins inhibit enzyme COMT which leads to higher norepinephrine levels (COMT degrades norepinephrine)

brilliant post. So increase caffeine increase nor-ep= better, I remember the limit being around 90 mg egcg per 50mg caffiene, If I took a 200mg caffeine pill does that number increase?
