Can two rockstar energy drinks in under 12 hours kill you?!

Question: Can two rockstar energy drinks in under 12 hours kill you?
Im 6'4 and around 190 pounds if that makes a difference. And if it doesnt kill you, are there any bad side effects? Is two alright?

Hello Stew! 2 Energy Drinks under 12 hours would not kill you unless being allergic to caffeine or mixing it with alcohol which in that case would create a death serum. However, 81 cans of Rockstar would officially kill you. How do I know? Go to… This is a very cool site in which you enter your weight, and type of energy drink. Then it gives you then the total amount of drinks to take to officially kill you. ( A little awkward but interesting to know)

Hope it helped!!!

My own!! I've been searching google in my free time and found that interesting webpage.

Nope, you're good. The lethal dose of caffeine is about 160mg/kg, or 80-100 cups of coffee in a concentrated time. Rockstars have 160 mg of caffeine in every 16 ounce can. This is roughly equivalent to a cup and a half of coffee (approx. 130mg each). So in reality, you've only had about three cups in the last twelve hours. You're fine. Might get a headache, but water will help with that.

If you want to make sure, here's a link for body/lethal dosage:

Nope. I've drank 2 within 8 hours for all-nighters. I'm 5'9" and 135 lbs.


Your average person, no. I've known a few people with a severe sensitivity to caffeine, and people who are sensitive can be put in the hospital by that.

Believe me you are fine! I am what you could call a heavy energy drinker and i drink two red bulls a day! at worst maybe a little headache

Not at all. But withinin 13 hours?? You're screwed. :)

what are you crazy having 10 wont kill you its not poison
