First off. With regards to your TRT. You should be injecting the test twice a week. 50mg on monday and thursday for example.
My opinion about upping the dose and throwing in the orals. Wait. Youve only been on TRT for 5 months. Plenty of progress can be made on the TRT alone.
But you are a 45 year old man, so if you want to run a cycle, who's going to stop you? I still think you are far to overweight to NEED supraphysiological doses to gain muscle and lose fat at the same time. You should be able to do that just fine by dialing in the trt.
You should really check out the TRT forum in more detail. Youve made no mention of an AI for estrogen control. ANd the fact that youre injecting twice a month instead of twice a week is not a good sign. It does make a huge difference.
