[j-trupaz]

ok im thinking of going 2 the gym @ 6:30 and i wana take caffiene pills for the first time see if they actully will benefit me or not.
but i heard ur not supposed 2 take them after 4pm or u wont be able 2 sleep prolly

im just wondering how long before i workout should i take it and how long will the energy boost last?

200mg of Caffiene is like drinking a cup of coffee. Its not really a boost, just more alert. Now if you added 25mg of ephedrine with that 200mg of caffiene, and that would be a boost. Take em about 4 o clock and by 6:30 you will be kicking. Body will get immuned to them though.

The "pick me up" effect will deteriorate, but the metabolic benefits will not.

Personally, I am not a big fan of taking a boost of any kind prior to a workout. The energy boost is accompanied with an increase in blood pressure and heart rate. While an elevated heart rate is not a big deal during a non-cardio workout session, I consider elevated BP to be extremely risky, especially if you tend to hold your breath and use core muscles to assist with a lift.

I have nothing against use of ECA stacks, but I would not want to chance a stroke in the workout room. I won't take a stimulant within 4-6 hours of a workout.
