I am new to the site, I recently started HGH cycle. I took 2ius for first 10 days then went up to 4ius. Ever since I started taking 4 ius a day I have had pretty bad headaches throughout the day. Sometimes after I eat, the headache will go away or lessen in pain but its always here. Is there something I am doing wrong? is this a side effect that will go away in time? any help would be great. I am also getting tested this week from doc. to make sure I have healthy levels and not becoming a diabetic from this. Thanks for your time and help
