Was on 200mp weekly Cyp for TRT for years but kept getting hematocrit issues. Dr switched me up to 50mg e3.5 days (sat am and tues pm) for past year. Good news is hematocrit issues went away and E2 fluctuations not as bad but my Free T results on the LabCorp test keep showing very high. Range of 6.8 to 21.5 on test but my results show 27.2 up to 29 on Free T and Total T 900-1100. These were all taken on Tuesday’s (so Day 3 out of 3.5 for me). These numbers are way higher than my previous 200MG a week so seems odd. Same test cyp supplier from Kroger in same bottles, same syringes, etc.
All in all I feel ok, just a bit of brain fog but that has been my issue every since I started TRT 6 years ago. E2 ranges from 19-30 usually so that seems ok and I got the full panel ($700 in tests) early in the year and all things looked in range except for high free T.
Wondering is free T is really that high or if the test I get from LabCorp is not right. I do not notice any difference, am still 6’0" and 185 lbs and maintaining strength and muscle so no gain or loss now at 44 years old.
Thoughts on why free is so high? IM injections in glutes.
