From my readings, bodybuilders say the "clinics" prescribe as much GH as you want, it's mostly a financing issue, you get as much as you are willing to pay for. Furthermore, bhank knows the prescribed GH is very expensive and the prime Chinese is a fraction of that, so he might have a GH script and uses mostly Chinese GH. Of course I could be wrong but this is what I would do if I felt I needed a GH script for legal reasons.

I've seen prescribing info for GH in cases of damage to the pituitary gland or idiopathic low GH/IGF-1. They go by IGF-1 levels and the starting dose by legitimate endos start at .8iu and might be raised to 2iu but I doubt they would increase much more. I've said here many times that the GH scripts aren't really legal, the FDA, some years ago, said GH should only be prescribed to dwarves. Or is it midgets, I forget the difference.

The other legit reason is if you have damage to your GH releasing glands, or maybe if you even had them removed due to brain cancer. So the authorities could move on all these "HRT Docs but my impression is that they've already given up trying to enforce the law. BTW, my aunt went to an opthalmologist who asked if she's ever had her GH levels checked. It's very interesting that the eye doc suspected such, maybe by her eyes or her general physiognomy, things like ears or nose or whatever, I'm not sure lol. And what do you know, her GH was sky high due to a pituitary tumor which they removed through the nose... she dropped about 20lbs of fluid due to the GH reduction!
Jay Cutler has told bodybuilders to take as much GH as you can afford, other bbers have said the same. My roid dealer said he is gouig to do one single last prep for a show as he asked around and said other top amateurs in Europe used as much as 40iu a day which he isn't willing to do. I told him that dosage isn't necessary. He has been doing 10iu for a couple of years but now said he is going to 5iu because of finances, even though he sells the shit. I told him, knowing he's been as high as 4 grams of AAS, to continue the 10iu, but I would try to increase to as much as 20iu for his final push phase and then contest prep, just to make it really count. Those knowledeable say 20iu is very common in Europe, a bottle morning and night, all due to the cheap China generic. Some of it has been tested at 15iu in a supposed 10iu bottle!
My 60 year old training partner has been taking 4-5iu of GH for years but came off it because he felt it caused a lot of water retention, and he especially complained about face bloat. He lost 10lbs in a week dropping the GH, and now he paused the roids for 6 weeks and dropped a further 10lbs. I told him why not continue GH but lower to 1.5-2iu, as even that is increasing his probably nonexistent GH (due to age). But then he said "but I feel minimum is 4-5iu to actually 'feel it'" He is surprisingly strong and big considering age, though he carries a lot of excess fat, last year he made a deadlift PB after having juiced for 40 years and lifting for 45 years lol. I think the GH is probably helping him in a big way, I told him if I was him I'd at least take a "true" replacement dose, I would be afraid of losing my edge dropping all of it lol.
Regarding GH contributing to cancer, there was a recent paper where scientists argued that GH increases immunity so could "catch" cancers even before it develops. Then there is a study involving GH, DHEA and Metformin which reduced biological age (measured by biological clocks) by 2 years! The driver for this effect they think is all due to the GH, those other drugs were to combat the predictable insulin resistance, which of course is harmful. So it may increase the rate of cancer development but otoh it may decrease the incidence of cancers too!
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5348436/https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6826138/ The purpose of the TRIIM trial was to investigate the possibility of using recombinant human growth hormone (rhGH) to prevent or reverse signs of immunosenescence in a population of 51‐ to 65‐year‐old putatively healthy men, which represents the age range that just precedes the collapse of the TCR repertoire. rhGH was used based on prior evidence that growth hormone (GH) has thymotrophic and immune reconstituting effects in animals (Kelley et al., 1986) and human HIV patients (Napolitano et al., 2008; Plana et al., 2011). Because GH‐induced hyperinsulinemia (Marcus et al., 1990) is undesirable and might affect thymic regeneration and immunological reconstitution, we combined rhGH with both dehydroepiandrosterone (DHEA) and metformin in an attempt to limit the “diabetogenic” effect of GH.
