I have recently experienced symptoms that appear to be related to a B12 deficiency. It has taken about 4 months to find a healthcare provider who is willing to work with me on this health issue. I have read through several posts and have had many questions answered - this is a great support group. I have received my first vial of injectable Methyl B12 from Woman's International Pharmacy. I want to know what pharmacies/laboratories will mix (compound) the Methyl B12 for sq injections. Is there a pharmcy known for their quality/reliability in compounding active Methyl B12? Any information that I can get regarding this question is greatly appreciated.
