Managing Estradiol (E2) and AI use on Testosterone Cypionate

Managing estradiol (E2) is a balancing act, as some estrogen is essential for bone health, libido, and neuroprotection. At HeydayMD, we typically recommend starting with frequent injection schedules to minimize the hormonal spikes that lead to excess aromatization before reaching for an aromatase inhibitor. If you do experience symptoms like sensitive nipples or significant water retention, it's crucial to use a sensitive E2 assay and start with the lowest possible AI dose to avoid 'crashing' your levels. Our clinical team focuses on treating the patient's symptoms rather than just chasing a specific number on a lab report.
