sust 250 and propecia?

is it ok to take propecia when on sust 250? im asking cus i know you are not supposed to mix deca with
propecia, sust has test DECONATE in it. Does this test deconate have the same characteristics or can it
cause the same negative reactions as nandrolene deconate (deca) when mixed with prpecia?

any replies would be cool

Propecia/Proscar is fine with Sust, at least that is what my references say.
