Hey need some advise here, for the last 6 weeks I have been on an ECA stack. 2 weeks on 2 weeks off. My dad has seen the energy that I have when I am on it and he would like to know if it would be ok if he just took the caffeine. My dad was hooked on code red mountain dew whih has a ton of sugars and a ton of caffeine. Well, he wants to lose some weight so I told him to drop the Mountain Dew because of the sugars in it. Well, he did and now he has losed that energy used to get when drinking it. So, my dad is perfectly healthy, no diabetes, blood preasure is fine and he just recently had that all checked out. So, for his age what would be the maxium amount of caffeine that should be safe for him to take? I was thinking like a 200mg pill when he wakes up (8am) and then another 200mg pill in the early afternoon. You guys think this is ok??????
