If you have a copy of your BW please post it up. If not, get a copy for your records and start maintaining all of them as it will benefit you in the future. You should want to know why your T is low, not just that you have low T as that's not good enough. Many things can cause low T with hypothyroidism being a main culprit. It could also be simply due to aging. Regardless, you need to know what the cause is to enter into this with a clear conscience or to fix the issue.
You can be either primary hypogonadal (testicular failure) or secondary hypogonadal (pituitary failure) or a combination of both. This can help determine treatment as well.
If you do embark on TRT make sure your doctor is both familiar with, and willing to prescribe and AI and HCG. When it comes to testosterone delivery method, most here will tell you injections are the way to go. I agree with that but that's a personal decision and lifestyle / convenience should be considered as well. Patches, gels, pellets, injections and even long term injections (Aveed / Nebido) are options that are available. It's what works for you that's important.
With injections don't automatically assume you need 150 - 200 mgs per week. It's always best to start out lower (say 100 mgs) and then titrate dosage as needed. Starting higher and then having to mitigate unwanted side effects is not the best option, imho. Walk before you run in otherwords.
When it comes to where you want your T levels to land, remember that total T does not matter. It's your free T that matters as that's what works for you. Naturally most want their free T near the top of the range. Once you establish a solid protocol with reliable numbers based on BW then you're good to go for whatever extra-curricular activities you choose. Just remember doc's require labs so don't screw yourself.
Also know that simply restoring your T levels to that of a much younger man will do wonders for you over time. I'd strongly suggest you wait a year before deciding to cycle. You'll be amazed at the progress you can make with a high normal T level!
Take some time and read all the stickies here. Be prepared to discuss why you may need an AI and why you do need HCG. A female doc doesn't have testicals to be concerned with, you do.
