If you are concerned about high blood sugar, you can always test your blood sugar and see for yourself what it is. GH can cause higher blood sugar for sure and long term, with high dosing, this can be a problem, but I wouldnt just assume it was a problem for you. I would use testing to KNOW for sure. It becomes more of a problem as the dosing gets higher. Not to say it cant happen at 3iu, but it is less likely. And if you are going to run it long term, like for the rest of the time you plan to do bodybuilding, I would consider taking a month off for every 9-10 months you are on just to give your body a break. Really though, I would not just expect to have this issue. Many people use this dose or more, long term and are just fine
