Stu We've just been looking at the same thing and are going to use the Health Hub in Herne Hill (http://www.healthhub.london). We've used them before for other things and found them to be good. Not cheap at ?150 per dose for Men B but that seems to be about the going rate in London. The only other method that was suggested to us was to get your doctor to give you a private prescription for it, buy it from the pharmacy (around ?70 per dose) and then go back for the doctor to administer it - but I'm not sure how feasible this route is.
