Supplement this thread with a DRs appointment. Wish you the best sincerely.

Well based on your body size I dont think HRT will get you "huge" unless your diet is just "garbage". It takes sometime to get "huge"

Also keep in mind all doctors are not created equal. Some want to help, some just stick to numbers and are very rigid. Just be honest, but sometimes a second opinion is necessary to find someone who is willing to go the extra mile.
Endos sometimes are really hard headed too, if it's not exactly what they were taught in school they dont want to think out the box. My wife has hashimoto disease and regular synthetic thyroid medications really dont help. She found relief after trying armour thyroid. This took me 9 months to get her straightened out.

Guyz and Goose are right.
For base line get doc to send you to endo doc.
Get all bloods and test done and go from there.
Then you will know for sure and know what to do next.
Cheers

Bro Being 45 is still very young, but life and stress make us feel older. Goose24 and Halsey said it perfect.. go to a doctor. It could be a hormone thing or a medical issue.

HRT has it advantages along with its disadvantages. So do your research and find a good endo. My wife had an endo that was very over weight and told my wife that she just needed to eat less. She also prescribed Something to lower her appetite. My wife later found a great endo who helped lower her inflammation that became an issue after our kid was born.

So just do the research - and it will definitely pay off

Hope you get what you need bro. We all want to feel our greatest.

Goose24 has you below, you need to see a doctor and have him run a full blood panel, check your thyroid, prostate, e.t.c. And also welcome to getting older. Do it right and live a long happy life.

This is the best advice you’ll get...
1) go to your doctor and tell him what’s going on.
2) Have doctor recommend an endo doc
3) go to the endo doc and have him do bloods
4) based of your blood work formulate a plan.

Don’t ask random dudes on steroid board what to do. Go see a real doc.

Get blood work done, including test panel and thyroid panel. Then we can talk. No free lunch here, but with some work bloodwork and research you can become a new man. I'm 45 too and trt.

Review what your eating drinking, your sleep pattern. Make sure you get plenty of veg and fruit, Multi vitamins etc. Eat regularly throughout the day.

Not sure drugs are really needed? As once your off you could feel even less motivated?

My input anyway.
