I read a few profiles on this and basically all they said was it speeds up your metabolism by shutting off your thyroid and that its pretty much safe to cycle 9 months solid and off the other 3 months of the year and the safe to restart again.Does this sound correct?

Is it much safer than clenbuterol ?
Is it as powerfull or more powerfull than ECA stack & clenbuterol?
Should Eca stack or clenbuterol be cycled along with it?
Is cytomel easily obtained?Is is considerably cheap or expensive?
