Growth Hormone is one many hormones( epinephrine, cortisol, glucagon) that rises glycemic levels.That's one of the reasons it is mostly released at night , when glycemic levels are dropping at your sleep.The instant you inject it, glycemic levels start to rise. That of course, stimulate insuline release. With time,long usage with high doses, and specially in genetic prone people, diabetes can develop. At first, it is basically a "more glucose than I can handle"kind of situation, but at time goes by, and with no care, it leads to pancreatic failure, and insuline dependant Diabetes. If you are using HGH, you have to monitor your glicemic levels closely, cause you are going to be using insulin also.There is an answer for people usin HgH alone and being hypoglicemic.They are producing tons of insulin to compensate the hyperglicemia, and after a spurge of insulin ( endogen) becoming hypoglicemic.With time, as with others, pancreas will fail to overcompensate, and then... HGh/insulin it's a tricky combo, and along with diuretics are, IMHO, the most dangerous drugs to handle.They are not for begginers/uneducated.
