question on clen

I was reading the "Clenbuterol handbook", and it said:
"Clenbuterol loses its thermogenic effects after around 8 weeks when
body temperature drops back to normal."
Dose this mean that if I cycle 2 weeks on and 2 off that my body temperature will be raised for 6 weeks after my last dose? Or does this mean that if I cycle for more than 8 weeks my body temp will not increase after the 8th week?
Thanks

that means after 8 weeks Clen is in-effective.
but generaly speaking Clen. loses effect after about 36 hrs. which is the half life for the drug.
