    For ten years I have been using Douglas or Pure products as advised by and ordered for me by Howard Friel. He seems to have disappeared and is no longer responding to email or p[hone calls. I am a former cancer patient and have done well with his suggestionsd but am now for 6 months already without the supplemets he had ordered and it a)seems that I need a health professional to order, and b)I cannot find the Hi-do-Vitamins 1 and 2 in your listings. Please advise….
