I got some mad bloat when I increased from 12iu to 14iu, had zero issues until then which seemed odd. Looked at my diet around the same time and it was a period where I lost the taste to keep eating a rice dish I was using and id started skipping meals and eating shit.
Been experimenting with it over the last 2 weeks and I'm now 100% sure that the sides I've been getting (water retention, numb hands/feet, pain in hands, lack of grip strength) is directly tied to eating sweet foods (sugar, sweeteners??) and dairy (The dairy though might not be, it just happens to be in a lot of the sweet shit I've been eating).
Cut the shit food out and got back to eating CLEAN.... All the sides are gone in 3 to 4 days. I've done this 2wks in a row now to test it, worked the same both times.
I really think the side effects that people experience from HGH are directly tied to the types of foods being eaten. Eat enough of a clean diet and I'm pretty convinced a lot of side effects for HGH will settle down and allow increased dosages for some people.
