Thank you for the help here really appreciate it going forward I will look to get my blood tests done on my true trough day off the back of my injection schedule.
It does seem it was a lab issue I redid the test at the same time (so not a true trough as it was 24hrs after my last injection)...
Thanks - I am not taking any supplements for biotin - I checked the dosage as its the same as it was before 200mg / ml.
I will look to get a retest in the new year see where I am.
hi guys thank you all for sharing your TRT experiences and knowledge its really useful to hear about everything people have experienced and learnt. Getting things dialled is one the hardest things it seems and to have such a huge evidenced based repository is invaluable.
I am on prescribed TRT...

Too high can cause side effects; too low can affect well-being.

prostate health, and masculinization effects.

Directly available for cellular uptake and biological effects.
