I didn't imply anything about doing this at home, but I can see why it was assumed.
I am not recommending anyone do what I choose to do but since some will ask...

I have a Dr who specializes in regenerative medicine and used to sell Omnitrope for somewhere in the range of $200 for a mg (1 mg = 2.7 to 3 IU, depending on who you ask) which is about retail cost with no profit if you are just ordering one $1100 vial at a time. But... thanks to media coverage of athletes abusing HGH etc, the Dr's are afraid to prescribe it for anything other than short stature children. They do good work and the FDA would love to bust them for anything because they aren't selling what the FDA can regulate (yet...) - your own blood platelets (PRP) and stem cells derived from your own fat and bone. Those are much more expensive than Prolotherapy which is roughly 15% dextrose with b vitamins, pH adjusted and other secrets of the particular Dr. My Dr says if he were on a desert island he would want Prolo which costs a lot less, personally I don't feel I get the same results but the $ comes into play. The HGH added to such a cocktail doubles the effect in my opinion. It works. They know it, I know it. Sometimes I'll ask them about research I've done on my own to try to get their take (can only imagine it pissed them off at first, maybe it still does). Now days not so much time spent researching, I would rather live a life than dwell on my own suffering while sitting in front of a computer monitor and the problems that creates. I make my own regenerative schedule. Example, do procedure "x" at this time of day... everyone go to lunch and when we get back inject "y" which would destroy anything it contacts (HGH). The HGH will have done a lot of its work, caused more release of local IGF during that time which will have had its time to do its work. After that period, the injection of substance "y" will go in stress the f out of anything it comes in contact with. In doing so, IGF and all of the other good growth factors that are in those cells are released. Substance "y" stays in the joint for a day, making squishy fart noises in the joint before being (ab/ad?) - sorbed. It's a bit amusing if you aren't in too much pain. I'm not going to name substance "y" but it is all around us, we breath it (well, sort of). The FDA doesn't look too kindly on the use of it and I don't want to name it because this Dr is the probably the only one in the region using it and I REALLY don't want to get my good Dr in trouble. This of course is not covered by insurance and is what I spend most of my money on. I want to walk without pain and don't trust some quack orthopod with a scalpel interested in billing insurance for all he can while not giving a f about my actual health. Last time I saw one he almost cut the wrong side of my arm open. I ran away and haven't looked back.

Long time to make a point: being that they can no longer prescribe Sandoz Omnitrope and knowing it would benefit their patients - they will allow me to bring in my own which "of course" I have a prescription for ;-|
So don't go calling these competent Dr's quacks just because of the B Bonds media coverage to distract people from Wall St criminals who should have been executed in the street - get in the way of progress. Stem cells work which is why the puppeteers who pulled Bush's strings had him sign an order outlawing research on it. Follow the money trail, the FDA is not your friend. Yes, I made two unrelated points in this paragraph which makes it seem I don't know how to argue but I'm typing fast so I can hit the save button and carry on with my life.

If you choose to go the regenerative medicine route, start looking for a competent Dr long before you need one. A good one will take several months to get in with. Make a visit for something minor then when something big comes around they already know you and you can get stuff fixed faster. The diet means NO anti-inflammatory anything, lots of collagen intake, bone soup, and the supplements you already take and then some. If you can bear it, the inflammation is where the healing is taking place (within limits, I'm generalizing because this isn't a scholarly article.
Obviously, the high IGF test and the low tests were done by different labs. Under the radar ya know? In a few months I will get caught by the latter and publish their results.
The other Dr who ordered the IGF tests is a general practice poser who does PRP (I won't let him do it on me, I have a competent Dr for that) and anything else he can get away with charging a ton of money for including unnecessary tests if he thinks insurance will pay for most of it while lining his buddy's pocket. I asked him to do the first test which I can't find the labs for. The two copies I found yesterday were done without my consent, at the time he said they were just routine labs. I asked to have the initial test done because I had a upper 300's IGF when using Hygetropin but didn't know my baseline. He tried to put me on Sermorelin at some absurd fee and I declined and told him why I had initially had the test done. I suspect he wants to bust me for using and it's really the only way he can. Anyway, I'm going to be on it at a low dose for the next 6-8 months while I regrow my knees, and have it injected into the knee capsule as I can afford to have it done by a professional. Right now that is every 3 weeks, and expect to slow down to every 6 weeks as it gets better. A few years ago - on other knee I was injecting all my GH as deep as I could along the ridge between the Tibia and Femur using a 1/2" needle. Not really deep enough I know now but it probably helped repair the area more than just randomly choosing an inconspicuous site on my body for injection.
Lesson: when your joints hurt, grinding through curls, squats, etc - and you are young - think about how they are going to feel in 10 years, 30 years, 50 years, etc...
Yes, HailRazor, it is roughly 1 IU per day but was traveling a lot so had long weekends. It averaged 1 IU a day, but I always did 2 IU for 3 or 4 days on / off. I also try to hit multiple spots (2-3) at once when possible... a little on this side of the knee, a little on the other, top, bottom, upper calf, lower quad. The two days before the test I did it IM in the arm at 2IU / day - just to have something comparable to the tests others here are having done.

Not proof reading this, hitting "save" and on my way.
Be Well
