t3 - too much could blow your thyroid and put you on meds for life
Clen - too much and you shake uncontrollably for one, not sure about other sides.
Clen - You normally start at 2 tabs ED and up it by 1 every day, you will find you max tolerance but dont go above 10 tabs. Prob wont need more than 8.
T3 - Dont go over 100mcg, youd be pretty safe then. Theres some excellent T3 dosing programmes flying aorund the boards. Someone else will prob have a link for you.
Imprtant thing with T3 is to taper up to max dose then taper SLOWLY down to get the body used to normalisation again.
Dont start until reading alot more on these two compounds.
