Yes, 600 mg of testosterone per week is significantly too high for any medically prescribed hormone replacement therapy (HRT).
To put this in context:
Standard Medical Dose (TRT): Typical prescribed doses range from 50 mg to 200 mg per week. Even at the high end (200 mg), doctors monitor closely for side effects.
600 mg per week: This is considered a steroid cycle dose, used by bodybuilders for muscle growth, not hormone replacement.
Taking 600 mg of testosterone carries substantial health risks, including:
Severe cardiovascular strain: Increased risk of high blood pressure, heart attack, stroke, and dangerous blood clots.
Estrogen-related side effects: The body converts excess testosterone into estrogen, leading to water retention, high blood pressure, and gynecomastia (breast tissue growth in men).
