Testosterone enanthate: doses, forms, storage and cost
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.

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.
