I have an appointment with a TRT clinic. I thought that they prescribe HCG but they do not. They prescribe weekly injections of test and an AI. This place sounded good because I would get seen by a PA and supposedly a doctor reviews everything even though I don't actually see him and my insurance covers it. Even though it's kind of expensive (four hundred dollars every seven weeks) I felt better knowing that I saw some sort of health practitioner and my insurance would pick up the bill after my deductible. My question is "is it always necessary to use HCG for TRT? Is there anyone on here that uses this protocol? If I didn't use HCG would my balls shrink?
