Muscle weighs more than fat, which you know already. So, although you’re on that damn scale everyday and it fluctuates between 187-190, those numbers might have taken a bit of a turn toward less BF and more muscle. That GH will not only cut some BF, but it will put on some muscle and tighten up your skin everywhere, too.
If you have time and one close, go get a baseline Dexa done. This way you will know where you stand on everything, including bone, which GH helps. Then, you. A start getting one done as frequently as you want to track your progress on the GH, higher Test and addition of Mast & TBol.
