Bioavailable Testosterone Test

I would prefer to be on injection just for the reasons mentioned. I spend a lot of time on the water during the summer so I swim a lot, also, I have a daughter who I do not want to transfer T to. I am now questioning if going off T was a bad descision. I feel like crap.

Bioavailable Testosterone Test

You might be correct. But do you think it is a good idea to see what my LH and FSH are prior to being on Testosterone to see if I am in fact Primary or Secondary or does it not make a difference.

Bioavailable Testosterone Test

Yes, there are red flags everywhere. Neither of the Docs spoke of Estradiol or SHBG or wanted to test. The Endocrinologist made a lot of good points as to the Urologists lack in testing LH and FSH so I thought she may have a better grasp on things. Also, my 1st testosterone test was 228...

Bioavailable Testosterone Test

Thanks Vince. This is helpful. I have not had my SHBG tested yet but will in a month. I just want to make sure I have all my basis covered so I can get an accurate diagnosis. My Urologist said I have primary hypogonadism from 1 Total Testosterone Reading of 228, I had an MRI of my brain...

Bioavailable Testosterone Test

So I clearly understand, you think I should have Free T, Total T and no need for Bioavailable T. I am very new to TRT... Also, what do you mean that I am on the wrong path. This is a new doctor who is an endocrinologist. My Urologist prescribed TRT but the Endocrinologist thought additional...

So I stopped taking TRT yesterday. It my be the placebo effect but it I am already feeling lightheaded and have a headache. I have been taking 100 mg of Testosterone Cyp each Sunday. Need to stay off TRT for a couple of months to have adequate testing done.

I will have PSA tests done as well. Sleep study results came in today and confirmed that I have moderate sleep apnea. Who knows, maybe this is my issue. I have been on TRT for a month and do not feel much different. I am curious how I will feel once I stop taking T.

My insurance company did cover the costs but I think that additional test should be done to have an accurate diagnosis as well as base line for future reference. I have had my thyroid, and cortisol tested. My thyroid tests typically come in a couple of points high but were well within range...

Hi All - I am 50 years old and have had symptoms of TRT for over 1 year. I do not drink, smoke or do any drugs and have never done steroids in my life. I eat a pretty balanced diet and used to run about 20 miles per week but since I am tired all the time, I stopped. About a month ago I went...
