I don't know which benzo is "strongest", but I don't think we could scientifically determine which one is "strongest" because everyone's body is different.

I suppose if you were really desperate to figure out which benzo works "best" for you, you could to undergo genetic testing to determine that. But genetic testing is usually at least $300 in the US, and that quote is *with* insurance. So you're better off just trying out different benzos, honestly.

Also, do you want short-acting (e.g., Ativan) or long-acting (e.g., Klonopin)?
