I have watched lots of Dr Doug also look up the Bone guru Dr Keith McCormick who has recently written a book on Bones. It took him 2 years to write with 1200 references. He had multiple fractures at age 40, hence his dedication to bone health. I think his book is available on Amazon and l expect he discusses anabolic versus bisphophonates. Good luck to all of us who took this dreadful drug. I have had 4 injections but l think l will have to have zoledronic acid to counteract the rebound effect. But need to negotiate to have 2g not 4g, then 2g 6 months later, and to have it infused over a longer period of time. Xx
