I was wondering if this product can be used of growth of cartilage since it has a similar properties to hgh, I had a knee surgery and I need to recover asap. The doctor just says take a rest and ther eis nothing to take to speed healing. My buddy is in china right now and he will get me a few vials of it, My only worry is that's made in china and I would like to know if it's a good quality product and reliable, some time ago I ordered roids from china and they were fake.
