I’ve just hit 40 years of age have seen a marked decrease in lean muscle mass over the last four years or so. I used to train heavy in my twenties, but in my thirties I’ve been up and down with my training as I’ve had to juggle family and work. Lately, training has been very difficult, with little gains even though I’ve applied sound training, nutrition, and rest. Clinically, I’m presenting some classic low-T symptoms - fatigue, loss of muscle mass, poor concentration etc…
I’ve had the full battery of tests and came up with some strange numbers:
Total T = 600 ng/dL
Free T = 6.8 pg/ml
Bio T = 156.77 ng/dL
SHBG = 54 nmol/L
Even more strange, I happened to have a Free T test when I was 26 and it was 21.96 pg/ml.
So there is an unusual decline over 14 years, not what you would expect. Total T is fine, but the Free T is quite low and the SHBG is high.
My doctor was ready to try me out on some T-replacement, based on the Free T results and historical decline, but balked when he saw the total T level.
Has anybody had similar confounding results? Any idea what it could mean?
