First why bother making an injectable Proviron you may ask
Well BAYER says
'The absolute bioavailability of mesterolone was determined to be about 3 % of the oral dose.'

We have an injectable recipe from a old SCHERING AG patent:
'EXAMPLE 2 In order to prepare an injection solution,
20.0 mg. of mesterolone is dissolved in:
618.6 mg. benzyl benzoate (USP XVII)
and 353.4 mg. castor oil (DAB 7, USP XVII);
the solution is filtered aseptically and filled into l-ml. ampoules under sterile conditions.

Proviron has a half-life of 12-13 hours:
'Thereafter, drug levels in serum decrease with a terminal half-life of 12 - 13 hours.'
http://www.bayerresources.com.au/resources/uploads/pi/file9420.pdf
12 hours ain't bad for oral administration, but in the patent they mention Mesterolone Cypionate for injection, too bad it never made it into production.
It would be nice if someone like @XKawN chimed in and suggested an extraction protocol from tabs, and if BB to oil ratio is too high
By the way do you think this recipe will also increase ORAL absorption? As Mesterolone ain't water soluble
'Mesterolone is a white to yellowish crystalline powder and is practically insoluble in water.'
http://www.bayerresources.com.au/resources/uploads/pi/file9420.pdf
It should be easy to crush Proviron tabs, brew them in oil/BB (as much as you can), and drink the liquid. Similar to oil improving Andriol absorption
Would MCTs or Olive Oil instead of castor oil work well?
Some math
based on the above mentioned Example 2
for 25 mg you'd need:
773.25 mg BB = 0.86 mL
441.75 mg castor oil = 0.42 mL
