to add: that NO conversion at all in a male usually goes hand in hand with EBV titres and low testosterone too.

When FT4 is at your level yet no FT3 shows, your adrenals are usually ok too..but 4x in one day salivary kit...doc can order think you can get that yourself if you order from Canary Club.

Also..other things in males can cause this pattern...but I PERSONALLY would want a RX from the doc for low T3. Would be nice to see a RT3 too.
