When labs vary that much, I have doubts about what is going on.
Had you been taking/stopping any medications?
Thyroids: Some levels looked really good.
Have you always used iodized salt?
HTC is getting high. If you increase T levels, will get worse. Can you be a blood doner?
Higher albumin helps with bio-T
Did you do anything to lower cholesterol?
LH/FSH suggest some degree of primary hypogonadism. You could test DHEA-S to see if that was low and rate limiting DHEA-->T.
Your bio-T is good enough that you should not be having low-T symptoms.
FT is released in pulses and perhaps first lab caught a peak and second a trough.
Essential fatty acids are just that, essential because your body cannot make these. Sources are fish oil, flax seed oil/meal, nuts.
Do you take any supplements?
Do you ever get leg cramps? That is typically a magnesium deficiency.
