I’m new on here, deciding to join after browsing for some time. There seems to be many knowledgeable and helpful people posting.
I’m a 48 year old male living in the UK. I have been suffering from the symptoms of low T for some years now. Main ones are low libido, often feeling lethargic/drained, some depression and low confidence. The exception is that my strength levels have been increasing steadily in the powerlifting exercises. I am in generally good shape at 93kg and approx 22% body fat.
I have been on TRT (transdermal) now for almost three months, after having low testosterone levels confirmed by two blood tests. It doesn’t seem to be working, despite my levels now coming up toward the upper end of the normal range.
I am suspecting a thyroid problem. I have had a thyroid blood test done by Medichecks, and have received the results recently:
TSH: 4.73 mIU/L (0.27 - 4.20)
fT4: 13.30 pmol/L (12.0 - 22.0)
fT3 5.81 pmol/L (3.10 - 6.80)
Thyroglobulin and thyroid peroxidase antibodies are at <10 and <9 IU/ml respectively.
From these, it appears that my TSH is high and my fT4 is low which would indicate hypothyroid. However, my fT3 levels don’t seem too bad.
I have started measuring my temperature with a digital thermometer (Geratherm Color), which is rather low:
05:30am 35.9°C (96.6°F)
09:00am 36.1°C (97.0°F)
14:30pm 36.3°C (97.3°F)
Some other results from an NHS blood test which may be of help:
Ferritin: 48 ng/mL (30 - 480)
Haemoglobin: 141 g/L (130 - 170)
Haematocrit: 0.435 (0.400 - 0.500)
These results were done at around 3 weeks on TRT.
While my T level is now fairly high, my E2 level is quite low at <44 pmol/L (0 - 192).
The only other thing I can think of is that I was treated with (Ro)Accutane for cystic acne when I was a teenager.
So I guess my question is, where do I go from here? More tests (rT3) for example? Try iodine or iron supplements?
Any help greatly appeciated!
