250ml or 250mg? You do mean mg, I assume.
"Estrogen blocker" once every two weeks?
Have you had bloodwork? THAT part is pretty important...
You've been on test for a year and a half at this dosage? Are you planning on being on test for the rest of your life, or going off of it at some point? That's a long time to be taking extraneous test... depending on your age, that could be long enough to shut down your natural production for good (you're not producing natural test right now).
For what it's worth, 200mg/wk is the upper end of TRT. I got bloodwork before starting, after 1 month, at 3 months... then every 6 months. @200mg, I'm at the high end of "normal". Some are that high with 100mg/wk.
CBC (hematocrit), Test, Estradiol. One should really, really keep an eye on hematocrit when taking Test, 'specially if you're above supraphysiological levels. I'm guessing that 250mg has you above.
