Compounding

Looking for some suggestions; I have some letro, it came in 2.5mg. Only want max 0.12-0.15mg doses. Also not interested in waiting for a different AI.
I’ve considered a method where you dilute a tab in water then use a dropper to dose, but not sure how stable the molecule is…
Seems like the only way is to chop up the tab under a microscope or get a extremely accurate scale.
If you have a minute, please provide some suggestions or experiences.

You can NOT dissolve the drugs in water.

You can dissolve them in alcohol, if your in the US, get some everclear, if not get something above 150 proof.

The coating on the outside of the pills sort of makes a mess, but it does work.
