I'll share some what I pm'd dk0223 yesterday (so it's out there for everyone)
My best friend use to complete. Once he gave it up he became more concerned about his health, he never ran a cycle again. But when he saw the results I was getting he bought a couple kits off me.
He's been really impressed with the results. And all he's doing is about two to three and a half iu per day of GH only nothing else except creatine and some other supplements.
The results aren't going to hit you in the face like running some tren or even something mild like anavar but it accumulates over time helping you reach levels that probably would not have been obtainable or much harder to obtain. I've been my weight and even leaner before but I didn't have the same pop/look.

Personally would I do GH by itself... NO, because of its negative impact on insulin resistance, and the cost to benefit ratio versus something like test it's just not even close, but instead of just trying to grow off AAS only; being able to implement HGH and insulin and getting away with less AAS is better because you have less androgen load, less side effects, and more gains than you would have had just going the single pathway (AAS only) route.
I need trt anyways. When I get older (and shift my concern to longevity, quality of life) I'd probably run something like 2iu of GH 4 days a week along with 140 mg test, and some metaformin.
However from a bodybuilding perspective it's probably better to come off, save money and resensitize.
