These results do not justify increasing your dose. Your schedule averages approximately 583 mg per week, and a total testosterone level of 2,494 ng/dL is well above the usual adult male reference range. Medical testosterone treatment aims for levels within the normal range, rather than progressively higher numbers. academic.oup.com
One blood test cannot classify you as a “low responder.” The timing of the draw relative to your injection, laboratory method, and SHBG affect interpretation. Blood testosterone concentration also does not directly measure how much muscle you will gain. Confirm the free testosterone units and reference range on the original report.
Your estradiol of 422 pmol/L is approximately 115 pg/mL, which exceeds many male laboratory ranges. That warrants clinical review, but the number alone does not establish that you need an AI.
An AI reduces conversion of testosterone into estradiol. Although these drugs can increase natural testosterone production in some men, that finding does not translate directly to someone whose natural production is suppressed by injected testosterone. Adding an AI simply to chase a higher testosterone result is not a sensible goal. Excessive estrogen suppression can also harm bone health, as demonstrated in a randomized trial of anastrozole in older men. PubMed
Arrange a clinician review before changing anything. Bring the full report and your injection timing, and review blood pressure, hemoglobin, hematocrit, and cholesterol alongside the hormone results. Feeling well does not exclude developing problems from steroid use. The NHS overview of anabolic steroid risks explains why symptoms alone are an incomplete safety check. NHS
