How can I get the degree of free online clinical pharmacy masters?

You don't. To get an accredited education you have to pay for it.

As far as I'm aware clinical degrees are NOT available online as they involve a lot of hands on work.
The chances of finding one of these for free are virtually NIL.
Any that you do find are most likely to be UNACCEPTABLE to anyone and just a pretty looking piece of paper.

I know that I would avoid a pharmacy like the plague if I knew the pharmacist has a free online degree.
