DMPS: non-prescription in Switzerland?

I came across this on the web:

"How to buy DMPS

IN THE US: We have not heard of a non-prescription source for DMPS in the US.

IN SWITZERLAND: DMPS is non-prescription. One can go to a drugstore and order it. They usually don't carry it in stock, so you order it then go pick it up. You can order some variations of dosages. Heyl makes it."

Can anyone in Switzerland attest to this?
