E/C STACK - how long do you have to take a break...

[cytrix]

is it true, that E/A stacks become less effective after a while, because the receptors get used to it? how long can you use it getting the full benefit before the receptors loose sesitivity?
how long do you have to wait and take a break before using it again? what about yohimbe, is it the same in this regard, that you should discontinue it for a while?

take 2 weeks off

The evidence is that the fat-burning thermogenic effect of ECA gets better, not less effective, with extended use.

If you're taking it partially for the "kick", then yes you'd want to cycle it.

heh I only take like 3-5 days off. usually 3 about once a month or so, but I also don't take it on off days and only preworkout.
