I am an advocate for anyone that truly needs trt. BUT a lot of people have uninformed expectations about what it will do for you. (even if you are truly coming from a hypo-gonadal state which a lot of people seeking are not).
NOTHING will be as important in your quest back to being in shape as 1)Lifestyle, 2)food intake, 3) training.
Even the most perfect hormone profiles, or more than perfect
will not overcome if any of the above are missing.
My advice is if you are overweight, lean to lose that weight. Seek outside nutritional help if you must. Start training. Again, seek outside help if you must. Hormones would be LAST on my list. You likely did not end up where you are now because your hormones were not ideal. It is not a bad idea to consult a dr who specializes in wellness....but be aware, there are many out there willing to write a TRT script and will promise you it will cure all your woes. It is not. But if you are truly suffering symptoms, it can help with those. But symptoms of low-t are very broad and mimic the symptoms of other hormone deficiencies, as well as being similar to what one might feel when they dont live a good lifestyle.
If you are out of shape, your cures will not come in a shot or a pill. That may turn out to be a very small part of the equation, but for true success, you have to recognize that many things about your life brought you to this point and you will have to willing to change those or nothing will work. In general most people fail because they really dont want to change. That is up to you but it is indeed possible. Good luck
