They seemed to use 5mg per kg twice per day in part of the study as well. The part that implicates negative results. If 0.3mg = 1.0IU / 0.7mg = 2.0IU roughly, doesn't this dose seem awful high of a dose?

It's hard to say. This is just an abstract and I could not seem to find a way to expand it or to determine if it's peer reviewed. Either way I totally understand your point: many unconfirmed sources and studies saying "good" or "not good" and it is truly hard to tell. It would be nice to find a peer reviewed scientific study performed on humans for specific injuries or surgeries. I know certain aspects of prolotherapy and various injectables directly into the joint sometimes include hgh and I would imagine there must be some type of study regarding this topic. But like you state, very few actual scientific studies.
I am new these forums and posts, so please forgive the delay. I have continued to use the hgh and I believe it is helping. The biggest thing I have noticed (besides the fat loss) is the recuperation time from workouts. I am talking about my physical therapy workouts primarily, where my leg muscles, tendons, and joints would recuperate in a matter of just a day or two - as opposed to the week or longer before using the hgh. I will keep up with because it seems to be helping, if not the injury/surgery recovery but the PT workouts that help stabilize and strengthen the knee joint.

I recently had acl surgery, the second time on this knee. I've been using GH s.c. 2iu morning and afternoon for healing purposes. I think it's doing the job. Doctor, his staff, and Physical Therapists all saying I'm doing great and slightly ahead of where I should be. 11 weeks since time of surgery 9 weeks since admin of GH. I'm 37 years old and I also have a good deal of cartilage removed from this knee. I had planned to keep this GH protocol for 6 months. Not sure what to make of this study posted. Anyone have any advice or feedback? Much appreciated.

Here's an article about the intra articulate injection of GH into the afflicted joint that shows it has benefit. There really doesn't seem to be a consensus on it though.

I considered doing my own intra articular injections of GH, but the risks were a little too much.
