How much BAC is actually needed to reconstituted the Retatrutide?

I am good with how to calculate dosages so that part is no problem. Just wondering how much is actually needed to fully mix the solution. I have so many insulin syringes in 0.5 unit increments in the house so I am not concerned with pulling the shots either.

I bought 10mg vials, it looks like a lot of the posts are saying 1ml per 10mg for easy dosing, some even double that amount.

Is 1mg per 0.1ml the ideal golden ratio then? Or is that just for simplicity? Thanks all!
