I’m sure your aware that you get bloods for the sake of knowing your overall values, in particular CBC, CMP, Lipids, etc. Getting either of the Testosterone values, in my humble opinion, really serves 2 things: (1) you learn over time to establish what your baseline Test levels are; in other words how sensitive you are to a particular dose. And (2) assuming you have established your baseline, you can use that as a benchmark when testing you and new UGL.
Free Test values works the same way ie establish your sensitive baseline. What’s fascinating to see is when you run other compounds, such as Mast, you can realize the synergy between compounds.
