For the info of other members who may be interested, my package of 100 (10x10) Panpharma (orig Rotex) injectable Hydroxocobalamin (Vit B12) arrived in six days. Total price was £74.38. I was not able to track it probably because it came via different companies in Germany and the UK. The good news is that the 'use by date' was Feb 2024.
I have to admit I found the purchase pretty easy on the Versandapo site - paying by PayPal, but translating some of the confirmation communications almost impossible. I was using 'Webtranslate'.
