Break between ECA cycles?

How long do you guys typical take? I figure 10-12 weeks on, 2-3 weeks off should be good right?

I go off a week every 4 weeks... any longer than 4 weeks on and it looses effectiveness with me.

You're staying on it way too long!!! Go with a 2 weeks on/two weeks off regimen. Your body will not build up a tolerance this way. If you have been on for 10-12 weeks, you should probably stay off for a solid month to let your body fully recover. Do ECA this way, and it'll be much more effective.
