We all know about these charts...
Powerhouse9's question is how are the detection times influenced by dosage, duration, metabolism etc...
Plus the charts seem to have been around for years. Drug testing must have improved, dont you think?
I don't think the testing has changed much: still mass spec and gas chromatography, as far as I know.
The question is not really answerable: dasage is the only of these variable that may be held steady. Duration will vary from person to person, and with different preparations of the same drug. More importantly, metabolism will vary person to person, and vary in the SAME person over time and depending on even more factors (general health, activity, diet, exersize, liver or kindney disease, etc, etc.).
And yes, pharmocokinetically, a single 1000mg dose of , say, test cypionate, will be detectable longer than a single dose of 100mg of cyp.
