## 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 a given volume 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.

## What the labels and the guideline say

| Source | What it says |
| --- | --- |
| Depo-Testosterone (testosterone cypionate) label | For replacement in hypogonadal males, 50 to 400 mg every two to four weeks |
| Testosterone enanthate label | Total doses above 400 mg a month are generally not required; injections more often than every two weeks are rarely indicated |
| Endocrine Society guideline (2018) | Typical starting doses of enanthate or cypionate: 75 to 100 mg a week, or 150 to 200 mg every 2 weeks |
| Endocrine Society guideline (2018) | Aim for testosterone levels in the mid-normal range during treatment |

## What judges whether a dose is enough

- 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.

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.
