The active life huh? I dont know bro? I think it has to do with how much aspirin u take with it. I believe taking the a=aspirin is to prolong the effects of the ephedrine and caffeine. Most will say to stack with 81mg asprin since u usually take the stack 3 times a day and if u take the full size asprin of 325mg each dose, thats a lot of aspirin a day and bad on ur liver. Id say i feel the effects the most the first week im on and for about 2 hours at a time or dose. After 2 hrs i dont feel like im on speed anymore, haha!

I have asthma/allergies and I was thinking about taking it when I go to Mexico City in June. It is a very pollutated city and think that it would help with my sinuses and breathing.

I was just wondering how far I should spread my doses out based on the active life (how long a single dose stays in your system).

4 hours is the active life, it is stated on the box of Vasopro, or rather it is stated to take every 4 hours but not exceed 6 tablets in 24 hours.

^Yup. About 4-5 hours.
