I wouldn't recommend rushing into TRT. It's a lifelong commitment. Injecting test once or twice a week, plus another couple of HCG shots on top of that, can get pretty old, pretty quick. Yes, it does become a routine. And yes, it isn't horrible. But, it can become a pain in the ass when you are on long-term travel or have a busy period in your life. I've been on for several years now, and my conclusion is that I wouldn't be on it if I was able to land somewhere in the middle to upper-middle of the normal range, naturally.
That being said, I'd see what your PCT numbers are, assuming you did a PCT. If you are in the vicinity of 600+, don't think about TRT. Those of us who are on TRT would kill to be there. Don't tank your HPTA because some legal juice sounds like a good thing.
If you do need it, several repeated blood tests will show. You will feel the typical symptoms of low T such as low libido, no energy, etc. If you check those boxes and your diet and lifestyle are in check, a knowledgeable and competent doctor will recognize the need for TRT and set you up. A knowledgeable doc will know about the TRT trifecta: Testosterone, HCG and an AI, if needed. The easiest way to find a knowledgeable doc is through a TRT clinic. If you feel like trying primary care docs, endos or urologists, you could be in for a long journey. You may find that guys on TRT in your area can refer you to a good doc, or you can spend lots of time and money trying to find one who knows their stuff. It's amazing how many endos and urologists know very little about, or are afraid to touch this area of practice. It seems to be the stigma of prescribing a steroidal hormone and the association between athletes and the misuse of steroids. I liken it to diabetics though: if you are diabetic, you are deficient in the ability to secrete insulin, and you are prescribed insulin. Why should it be any different if you cannot produce enough testosterone? And don't let a doc tell you that 300 ng/dL is a normal number because it is in the normal lab range. It may be normal if you are an 80 year old man, but you aren't. If you get fed that line as I was several times before initially going the clinic route, it's a good indication that you are talking to the wrong doc anyway.
