Wow, Robbie,
There are so many ways to answer this question.
The thing about the cyx3 is that the clen portion is not as effective after the first 3 weeks. (some claim two weeks)

So I would say like do it this:

1) Run the CyX3 alone for two-three weeks.

2) After the above, do T-3 solo for two weeks

(I belive you can shorten the clen off period from two weeks to one week by using a dose of Benadryl about 36 hours after your last dose of clen and do this for three consecutive nights before bed. This clears the receptors of clen. But this is only my theory)

3) At the end of two weeks, or one week with the Benadryl treatment, continue (start taking again)
clen/T-3 cycle for two more weeks.

At the end of this time decide whether you wish to continue by taking another clen break and so on.
