Man I wish I had time to do some searches, bushido bad boy had some seriously long threads where he and others went hard core trying different protocols of GH, IV, IM, ED, EOD, every 3rd day, and they explained why they thought IM and IV were superior, pulsing bursts like our bodies naturally do…so less chance of shut down, and I think but do not quote me, that IM makes it peak fast and is more useful than the slower SubQ release and some of them even said in those threads they thought SubQ was “wasting it”…BUT there are tons of dudes on SubQ, including those ungodly yoked 60-70 year old doctors on commercials and Ive seen on TV haha, so the stuff must work SubQ too that is the way they do it. I do not believe those old farts are doing real HRT, because if you are 50, 60, 70 and stronger, more ripped, and more horny than you were when you were young than you are far above your normal hormone output!
I dont care if I cycled, and I have good genetics, I am never going to be as strong, explosive, and horny as I was in teens and early 20s playing college ball and powerlifting! My body could not handle those loads Id detach and tear all kinds of stuff, but I am high mileage. I have been drag racing, mud bogging, and crash up derby my body for decades. But yea if you have time search GH pulsing, GH IV, BBB (bushidobadboy) on here. That dude was wicked ass smart, I wonder if he is still around. I have not been on here much due to work and other life challenges, but this always has been a trusted source of passionate guys.
So yea I think what the nurse told you is reverse what I have read on here, IM is for fast strong pulse like the body might do naturally, and SubQ is slower release so might inhibit the bodies natural output. So that is what I have been hoping, that by going M/W/F IM, that I am still keeping some of my natural GH and not shutting it down totally. I also train in a manner I hope I pulse GH, heavy on the compound ground based movments, and end workouts with 10-15 minutes of short high intensity intervals with short rests. I also supplement lots of the GH support amino blends before bed, and take Xyrem (GHB) from my doc to help promote deeper sleep and supposedly more GH. Deeper sleep should increase hormones regardless, I never took sleep seriously until my 30s…but guys trust me, research and experience tells otherwise, deeper stages of sleep are CRITICAL for our hormones and for our cognitive function.
I have thought of coming off GH for a while just to see how I feel, but then I am like what the hell I know its doing good stuff for me why get off, I will only get off if I have to. The Test on the other hand, I wish I could do a restart and not pin the rest of my life if I could get my levles back up to normal, but because of health issues, and then 3.5 years on HRT, I am sure I am shut down hard if not for good now.
Yes my pharmacy changed me from Omnitrope to Norditropin. It comes in a “pen” which has a knob you turn and “clicks” as you turn it, then you push a button and inject it. It is not dosed in ius and I used to have it figured out how many ius a week I was on, but now I have no clue
I am not gonna do IV…not into that, but I am sure sometimes I end up shooting in a vein when blood squirts out my quad so maybe I am psuedo IV sometimes 
One thing I have not had the time to read up on, is some fellas on here speak about concerns about causing diabetic issues using GH…which I need to read up on…if that is the case I need to take every precaution, and even consider getting off it from time to time if that helps reduce chances. So much to learn and read…and doctors say different things, different HRT clinic or doctors websites say different stuff, depending on the forum you visit guys swear by different methods, doses, protocols, etc. I am not sure which doctors are tuned into what really works, I would imagine if a doc was open to reading up on the bodybuilding scene, intervewing guys who have been doing it for years, and doing labs with guys trying different protocols over a long period of time, we might get some more concrete answers!
I cannot promote it enough though, for any age with soft tissue injuries or recovering from surgeries, hit the protein and BCAAs hard, fish oil in high doses (for many reasons including anti inflammatory), I am a firm believer in high dose vitamin C (its cheap why not, I do 6g day orally and when I have time get 30-50g in an IV). Get quality sleep, which if you struggle with sleep, google progressive relaxation, maybe read up on some basic mindfulness, Dr. Herbert Bensons Relaxation Response, do some positive imagery seeing the bodypart or injury healing and see yourself back to lifting and performing as you would like, and if you can afford it try deep tissue massage, Active Release Technique, foam roll around the injury (and you can use LAX balls, golf balls, etc to dig in around the site) . Also stretching, if you can find a good PT or sports ortho chiro who knows how to do functional movement screens/evals, they can help stretch muscles in ways that help release tension on injured ones, do tissue work, and stuff really helps. I also think stuff like dry needling and accupuncture could help, anything to get blood flowing. And also any sort of stim, compex units, game ready treatment system, vibration platforms, Normatech, etc…so many new ways to work on recovery…if you have a high speed sports medicine office near you they might have some or many of these things to try out.
And forgiven1…I feel for ya bro. I will not write a book about my life and injuries, but I have been training 25 years now, its as much a part of my life as brushing my teeth and putting deodorant on. I have been through hell and back a few times in my life with injuries and health issues that stopped or threatened my training, if you need a ear to bend shoot me a PM and I will give you my number.
