My blood test results on test cypionate

[RotnGun]

7 weeks ago I changed my TRT protocol to test cyp. My dosage has been 9mg/day injected by IM and 75iu of HCG injected by SQ. I recently had my blood test done. As last time, I did 2 test in one day. One test 8 hours after injection, and second one 25 hours after injection. Last time I was doing test enanthate at 12mg/day and between the 2 test, there was a wide difference of total test of 522ng/dL and estradiol of 31.5pg/mL within 25 hours. This time, I just have a minor difference of total test of 12ng/dL and estradiol of 2pg/mL within 25 hours. Why the large difference between 2 esters? I don't know. Maybe the test enanthate was in MCT oil while the test cyp was in cotton seed oil? The blood test were done at Lifelabs and I converted everything to the american metric system for simplicity. I used the online calculator for the free test.
