I get them from one of the few doctors who from experience know that some patients need injections even every second day. Authorities have been after some of them, but now they should have mutations from gene tests as a proof for this. But I also had a doctor that recommended me to buy MCbl in Spain without prescription. I don´t know if this is possible any longer, but before friends travelling bought MCbl for me. Have you had a 23andme test? What ingredients are there in the HydroxyCbl as you get an allergic reaction? Are you convinced that the diagnose pernicious anemia is correct? Do you get intrinsic factor as a supplement?
