What you will see from GH is a slow long term recomp effect. The main thing you’ll probably see right away at 52 is faster recovery. That in itself is going to lead to better muscle growth. Of course its also going to come down to diet. If your diet isn't right, you’ll still hold fat while on GH. If you want to push the fat loss further and your diet is on track, look into t4 at 50 to 100mcg. This will increase your stores of T4, which is converted to T3. On GH, your body will speed the process of conversion of T4 to T3. Also, yes, more test would help with muscle growth! Going to 300-500mg would be a good level to really see a nice difference
