4 days after my weekly 200 mg test cypionate injection (Dr. administered), my total test was 678 ng/dl. This is normal for me on this protocol. What surprised me is the Free Test value that came back of greater than 49 pg/ml (reference range 6.8 to 21.5 pg/ml). This was the first time I had pulled the LabCorp Testosterone, Free plus Total LC/MS test. To this point, my doctor has used the calculated free test value that uses SHBG, Albumin, and Total Testosterone. Using this formula, I would have expected something between 15 and 18 pg/ml (within the reference range).
Anybody have an thoughts on why the measured free test might be so high for a middle-of-the-range total test?
I don't know that this is relevant, but I recently crashed my e2 and have since gotten off the adex entirely. Also, my SHBG is generally at the very low end of the range and total test prior to treatment was 167. I am 42 years old.
