Is 1 ml of testosterone a week enough?
Short answer
It depends on the vial. Testosterone cypionate comes in 100 mg/ml and 200 mg/ml strengths, and testosterone enanthate vials are 200 mg/ml, so 1 ml a week is either 100 mg or 200 mg a week. The Endocrine Society’s 2018 guideline lists typical starting regimens of 75 to 100 mg a week, or 150 to 200 mg every 2 weeks. So 1 ml of a 100 mg/ml vial is within the weekly range, and 1 ml of a 200 mg/ml vial is double the upper weekly figure. Whether any dose is enough is judged by blood tests and symptoms, and only your prescriber should change it.
What 1 ml contains
| Volume | At 100 mg/ml | At 200 mg/ml |
|---|---|---|
| 0.25 ml (25 units on a U-100 syringe) | 25 mg | 50 mg |
| 0.375 ml (37.5 units) | 37.5 mg | 75 mg |
| 0.5 ml (50 units) | 50 mg | 100 mg |
| 0.75 ml (75 units) | 75 mg | 150 mg |
| 1 ml (100 units) | 100 mg | 200 mg |
Read the strength printed on your vial. The same volume from a different vial can be a different dose.

How "enough" is judged
Blood levels. Your prescriber checks testosterone during treatment and adjusts the dose to reach the target range. For the weekly autoinjector Xyosted, the label times the check 7 days after a dose, after 6 weeks of treatment.
Hematocrit. Testosterone can raise red blood cell levels; the Xyosted label advises checking hematocrit about every 3 months.
Symptoms and side effects, discussed with your prescriber.
These are the checks a prescriber uses. They are not a target you can set for yourself, and no dose on this page is a recommendation.
Weekly vs every two weeks
The Endocrine Society lists both a weekly schedule and an every-two-weeks schedule. Your prescriber chooses the schedule and checks levels at the right point between injections.
