I am sorry this is literally made to kill multiplecelluar life, how in the hell can you claim that a high dosis is safe?

I'm only claiming that a scientific study claimed that. Which it did. Scientific studies can be wrong, I guess.
I'm not encouraging anybody to take that high a dosage (or even to take the drug at all) I certainly didn't take 10x.

And how did you even get the adequate pharmaceutical equipment to get a non-lethal dosis?

....because I got it prescribed by a doctor?
