Again IG - u are confusing the half-life of the compound with dosage requirements - certainly not saying that everyones requirements will be the same - ur sensitivity and estrogen conversion ratio (which seems to vary with people) will determine the need for dose amounts but not the half life of the compound. Some people (like arnold) dont seem to have little need for aromataze blockers while others can get bitch tits on 400mg of test. point is - u can take 1mg or 1KG but that ont change the drugs half life - of course with too high a dose and then the the eccess drug is likely to be excreeted as it has no available receptor site to bind to.
