I bought the $500+ Bone Coach program and could not stick with it, because I could not get any cooperation from my doctor, who just wanted to prescribe meds, testing not an option. If you have a doc that will fully cooperate on the comprehensive testing, and money to cover the cost of the testing that your insurance will not cover, then it might be very useful. Or if you are just at the beginning of looking for answers. I just found trying to get a doc on board very stressful. I have stopped my bone loss, and recovered some density on my own, and would simply love to have support from a doc. But my PC and the Endo she sent me to just want to put me on drugs (without any testing of any sort beyond DEXA and a super basic metabolic panel) and I simply refuse. Mind you I already lift aggressively, eat well and am in very good condition otherwise, which is how my five years of improvement have happened. Good luck to you.
