As I already wrote in another topic:
The synthesis of all methcations is approximately the same,
except for some details and reagents.
So here it is: 4 MMC average wholesale price is 4000-5000 euros per kg.
But you want to buy A-PVP/PHP for 1500 euros per kg.
The question is, what is the point for a chemist to do the same work, but three times cheaper?
This is precisely why there is a shortage of A-PVP on the market.
