*protocol 91mg T/week split 26 mg EOD.
Your FT was tested using 2 different assays (direct immunoassay/Equilibrium Ultrafiltration).
The same day you had your blood work done.
Your TT 759 ng/dL (reference range 264-916 ng/dL) was tested using the most accurate assay LC/MS-MS yet FT 12.2 pg/mL (reference range 7.2-24.0 pg/mL) was tested using the piss poor direct immunoassay which is known to be inaccurate and should not be used/relied upon when testing free testosterone!
Would have you and anyone believing that your trough FT is on the lower end.

Second FT test result.
Your TT 759 ng/dL (reference range 264-916 ng/dL) was tested using the most accurate assay LC/MS-MS and FT 29.45 ng/dL (reference range 5.00-21.00 ng/dL) was tested using Equilibrium Ultrafiltration which is one of the most accurate assays.
ED or UF are the assays people should be using/relying upon when testing free testosterone.
As you can clearly see your trough FT is high.
You are hitting almost 4% FT.
Yes, this is even with a highish SHBG 44.6 nmol/L.....who knew lol!

Just imagine how much higher it would have been if you had tested it using the same lab (Labcorp)/assay (Equilibrium Ultrafiltration) when you were running a very high TT 1167 ng/dL with an SHBG 36.6 nmol/L back when you had labs done on Jan.18/2022?
This is why it is critical for anyone pre/post trt to always use the same lab/same assay (most accurate) when getting blood work done!
Just imagine how many men have no clue where their trough FT level truly sits.
