On a side note, I asked the compound pharmacy if the pps they use is bene, ELMIRON, Arthropharm and they said no. Part of reply pasted below. Would be good to get any thoughts you have.

'Arthropharm' is another commercial product sponsor/manufacturer, not a GMP (Good Manufacturing Practice) Active Pharmaceutical Ingredient (API) manufacturer, thus we cannot source PPS ingredient material from them.

As well as being US FDA GMP certified, our manufacturing supply resource for PPS also holds US FDA DMF (Drug Master File) registration for their PPS API material.
