## Short answer

Testosterone enanthate is a long-acting form of testosterone given by injection. It comes in two FDA-approved forms: a 200 mg/ml multi-dose vial injected into the muscle, and Xyosted, a single-dose autoinjector given under the skin of the abdomen once a week in 50, 75 or 100 mg strengths. Testosterone is a Schedule III controlled substance, and treatment starts only after morning blood tests on at least two separate days confirm low testosterone. Your prescriber sets your dose.

## The two forms

| Detail | Testosterone enanthate vial | Xyosted autoinjector |
| --- | --- | --- |
| Strength | 200 mg/ml, 5 ml multi-dose vial | 50, 75 or 100 mg in 0.5 ml |
| Where it is injected | Deep in the gluteal muscle | Under the skin of the abdomen |
| Label dosing | 50 to 400 mg every 2 to 4 weeks; total doses above 400 mg a month are generally not required | Start at 75 mg once a week; adjust based on a trough level 7 days after a dose, after 6 weeks |
| Oil | Sesame oil | Preservative-free solution |
| Storage | Room temperature, 20 to 25°C (68 to 77°F); warm and roll the vial if crystals form in the cold | Room temperature; do not refrigerate or freeze; protect from light |

## Before you start

The labels say to confirm low testosterone with morning blood tests on at least two separate days before starting.

## Monitoring the labels describe

- Hematocrit about every 3 months (Xyosted label), because testosterone can raise red blood cell levels.
- Blood pressure, which testosterone can raise.
- Prostate symptoms in men with an enlarged prostate.
- Signs of blood clots in the legs or lungs.

These are the checks the labels describe. They are not a schedule you can set for yourself, and no dose on this page is a recommendation.
