How to calculate a dose for things like digitoxin?

[Azlia]

I been cheeking and digi seems like the most peaceful, i was also considering clonazepam while swimming, i'm still looking sources to get digi, my only doubt is how to calculate what amount should i use and if in injection or oral?

briefly looked into this and there are quite a few case reports on suicide attempts. this person ingested 7mg and died. 0.3mg/kg is the LD50 in rats, however this doesn't always correlate to the human LD50.

do you know perchance what was the weight of this person?
