I had a very bad compound fracture of my femur. After 6 months, I was told that my femur hadn't healed any since my 3 month follow up, one surgical screw had broken, and the rod in my leg had moved, and I would likely be having another surgery to try to reset it and add plates to the fractured area that wasn't healing But he wanted to give it more time first, and see how it looked in 3 more months. My wife (a nurse) started researching alternative meds and supplements for healing and found this. So, Ihave been taking it every day for since she found it. Well, 3 months has passed and the latest xrays show that my femur is healing again, my muscle strength is much better, the rod is hasn't moved any more, and the hardware in my leg is still where it should be (aside from the one broken screw), the pain has diminished by nearly 90%, and I won't have to have any further surgery if the healing stays on course. So, it seems to have worked well for me. Expensive? Sure... but less expensive than another surgery. Taste bad? Ehhh it isnt great, but it's better than hospital food. I mix it in with fruit, juice and ice and blend it into a smoothie and it is very tolerable.
