    Considering coming off after three years - advice needed

    Considering coming off after three years - advice needed

    Thanks for the help. Thyroid is my best bet, though I do think TRT is still an issue, as it gave me ED and worsened my libido well before I had any thyroid issues. Not sure if the two are interlinked.

    Considering coming off after three years - advice needed

    Thank you for your advice. With everything you said in mind, do you think I should remain on TRT? My levels were low pre-TRT, but my lifestle was also extremely poor. I just started a new job and was only getting 4-5 hours sleep a night, diet was all over the place etc. I'm not sure which of the...

    Considering coming off after three years - advice needed

    My situation is complex and this post will likely be quite long. I'm in quite dire states at the minute, so I'd be extremely grateful if you could read the post in it's entirety.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
