Except what you wrote isn't what the parent comment wrote. If we know what doses other people are prescribing as "effective", then we do know the effective dose. Their immediate sentence before said we don't know the effective dose. And you accuse me of being obtuse. This is aside from the point that there's an effective (and not lethal dose) of Ivermectin for treating parasites. It does not follow that that same dosage would be effective for covid. We have no idea what that effective dose might be for covid, if any. It could be lethal, it could not be. That's the entire point.
