When starting or adjusting testosterone therapy, one of the most common questions is: is 1ml of testosterone a week enough? For men using TRT for muscle growth or hormone optimization, understanding the right dose can make a major difference in both safety and results.
Let’s break down how 1ml translates into milligrams, whether that dose is effective, and how it compares to what bodybuilders or optimized TRT users might experience.
How Many Milligrams Are in 1ml of Testosterone?
In most TRT protocols, 1ml of testosterone cypionate = 200mg. So if you’re injecting 1ml weekly, you’re taking 200mg of testosterone a week—a standard high-end dose in therapeutic ranges.
Some formulations vary (e.g., 100mg/ml or 250mg/ml), but at Endless Vitality, our protocols usually involve 200mg/ml cypionate unless personalized otherwise.
