“I have read some amazing replied by extremely intelligent people.”
You must set the bar really low =)
First off, how old are you? That info is slightly helpful.
Testosterone levels can vary WILDLY between morning and evening. Although your score of 330ng/dL is low, it could be that your AM score is well within the healthy range.
“Tough time getting to bed at night, tough waking up. Feel brain fogged. Drink coffee every day. Start feeling better around 4-6pm every day.”
This is kind of self-answering. You have a hard time sleeping, so you have a hard time being forced to wake up in the morning. Coffee keeps you going throughout the day, and you “get over” your sleepiness in the early evening. Then, I’m guessing that, since you’re more awake in the evening, you’re more active in the evening/night time. Since your brain is being stimulated, it’s keeping you from falling asleep. Lather, Rinse, Repeat. A lot of that is guesswork on my part, but aside from the caffeine consumption I could have written the same thing about myself.
Have you had a sleep study done to rule out apnea or other things that could be making your sleep less restful? Have you ever been seen/treated for insomnia? Do you ever “binge sleep”, like after several days of having little/no/really shitty sleep do you sleep for an insane amount of hours if the situation permits?
Just an FYI, insomnia can cause low testosterone.
“Perhaps a serious deficiency or adrenal fatigue?”
Your cortisol looks fine, but I don’t know what the result should be since it wasn’t the 8am test. The 8am test is a specific test, not a general “you should test it sometime in the AM” type thing. There is a non-8am test, which I’m guessing is what they did for you, but I know so little about it I won’t comment other than to say that you’re smack in the middle of the range, so it’s really unlikely you’re having adrenal issues.
For your other labs, don’t kill yourself to get up early and get them tested, but do try to get them done as early as possible. I don’t see 9:45am being a problem.
You should get your ferritin levels checked since this can cause fatigue issues as well. Getting B-12 done too would be good.
You probably want to bring your D3 up. I don’t get a ton of sunlight so I take 5k IU a day. Wouldn’t hurt to start with that dose and see where you are in a month. Opinions will vary, but getting it between 60 and 100 is a good goal.
Aside from that your labs look good. Why is your doctor adding another round of tests? Just would be good to clarify you and him/her are digging at. You’re going to want to retest everything you had above if possible, just so you can get your morning “peak” values.
Good luck! Hope I didn’t answer this too late/past the cut-off.
