Buying Mutaflor in the UK

Hi, i am taking a trip to london this week. Does anyone know how i would go about buying Mutaflor while i'm there? I know it is not allowed to be sold in the US but i hear it can be purchased abroad and brought back on a flight. All trivial things aside, where can i purchase the probiotic? Any suggestion for leads?

Any success stories? I am missing the E. coli strain all together since my vancomycin treatment, mutaflor is said to be able to bring the strain back and re-colonize the gut.
