try upping your TRT dosage and if your taking an AI try lowering your dosage or removing it all together (as higher serum levels of estrogen will increase IGF)
Agree with both recommendations. At your level of T, there is absolutely no need for an AI or E blocker. You could stand to boost your E by increasing your T slightly so that it is closer to the upper 75th percentile of your age range (30 to 40 Y/O).
