Has anyone injected Ivermectin 1% Solution NOT the paste? And can the solution be taken orally, and if so, How Much?

I am trying to determine an appropriate dose of this 1% solution from the UK, not paste, and with no additives. Out of an abundance of caution, and because I don't want to do more damage than good, I would appreciate any insight into an appropriate dosage protocol.

I know most have been gobbling up the paste, but I wanted to insure I got the cleanest product I could find, thus the 50mL 1% solution.

I have read that taking a dose or more before symptoms arise might be the ticket to avoid the Vid altogether. I have also read:

The dose most commonly used in clinical trials is IVM 0.2-0.6 mg/kg PO given as a single dose or as a once-daily dose for up to 5 days.

I began to do the math, not my greatest strength, but ultimately determined that whatever I came up with, I would run it by the glp soothsayers anyway, for reassurance that I have a viable option in lieu of the horse paste. I realize now that I probably should have just gone with the paste, as I've not read any legitimate piece or posting where the paste was the wrong way to go. Unfortunately, I bought the solution months ago, long past a return period, I think.

So to all you chemists, doctors or Indian chiefs, how much of this 1% (0.01) solution should I shoot into my body, assuming I do so ahead of the bug; and how much of this solution should I take if early onset symptoms begin? Assume I weigh 180lbs and I'm old enough, but not in the high risk age group.
