Glad I could help! I waited for sooo long to have a biotin(-only) supplement sold in Finland... And Hübner is a high quality brand, too!
I got mine at Ympyrätalon apteekki, and I have seen Biotisan at Yliopiston apteekki, too. But it's worth asking at other places, too. Sometimes pharmacies hold stuff - especially vitamin stuff - "under the counter" or in the drawers below the actual shelves.
Ympyrätalon apteekki didn't carry the 90tab packet, but they ordered it for me when I asked. I'm not sure if YA carries the 90tabs, but I'm planning to ask...
Let me know if you found it! :bluegrin:
