You might try taking a full week off and giving it another go, starting at 2IU, assuming you reconstitute with 1.2 ml of water. I was having really bad CTS and major water retention (hands looked liked sausage) on my second kit of the 120s. I took a full week off and restarted. The water retention is basically all gone, and the CTS has minimized a lot. Someone else in here recommended that, because it worked for him, too. I also switched from morning injections to evening. My sleep has gotten better, and I have noticed faster body fat loss since I started back over two weeks ago. It also keeps me from eating late night.
Like I mentioned earlier, unfortunately, G is not an exact science like T replacement. Might be worth a try.? Good luck!
