It sounds like many of these effects are related to low blood sugar. Hyge's are strong, IME, on par with pharm grade growth. You may need to time your GH up with food consumption. Hypoglycemia can hit hard and fast after a shot is taken and can last an extended period, depending on how much you took and what your diet looks like. I would start by backig the dose down and makig sure that you get a good carb rich meal in your body before you inject. i would see if you get this effect at just 1iu. If you start to feel dizzy, take in some simple carbs right away and see if that helps within a few min. as long as you respond ok at this small dose, I would go up by .5iu every few days, always making sure to eat enough first. when you get to 4iu, you might want to consider spliting your dose into 2 daily shots of 2iu each, taking first thing in the AM and then again about 6 hours later.
