Clinical Information
Evidence-based details for healthcare providers
A valid prescription from a DEA-registered prescriber is required.
Limited to 5 refills within 6 months of the original prescription date.
Subject to state and federal controlled substance regulations.
Use only as directed by your healthcare provider. Your provider will decide how much to use and how often based on your testosterone levels, symptoms, age, and lab results. Do not change your dose, inject more often, or stop treatment without medical advice. If you miss a dose, contact your healthcare provider or pharmacist for guidance. Regular blood tests and follow-up visits are important during treatment.
Testosterone cypionate is a long-acting form of testosterone, the main male sex hormone. After injection, it is slowly released into the body and then changed into active testosterone. It works by attaching to androgen receptors in many tissues, including muscle, bone, skin, brain, and sex organs. This helps support normal male hormone activity, including sex drive, energy, mood, red blood cell production, muscle mass, and bone strength. Testosterone levels usually begin to rise within 24 to 48 hours after an injection, but symptom improvement may take longer. Some people notice changes in energy or sex drive within a few weeks, while benefits for body composition and bone strength may take several months. The effects last for days to weeks depending on the dose and dosing schedule chosen by your healthcare provider.
Do not use if you are allergic to testosterone cypionate or any ingredient in the product. Do not use if you are pregnant, may become pregnant, or are breastfeeding because testosterone can harm an unborn baby. Do not use in men with known or suspected prostate cancer or male breast cancer because testosterone may worsen these conditions. Do not use if you have serious untreated heart, liver, or kidney problems that cause swelling, unless your healthcare provider decides the benefit outweighs the risk. Do not use in children unless specifically prescribed by a specialist, because testosterone can affect bone growth and sexual development. Do not use if you have high red blood cell counts, untreated severe sleep apnea, or a history of serious blood clots without careful medical review.
This medication may interact with blood thinners such as warfarin, which can raise bleeding risk and may require closer lab checks. It may change blood sugar control in people using insulin or diabetes medicines, so blood sugar may need closer monitoring. Testosterone can increase fluid retention when used with corticosteroids such as prednisone, especially in people with heart, liver, or kidney disease. It may also affect the action of medicines that influence hormones, including some fertility treatments. Using other anabolic steroids or testosterone products raises the risk of side effects and should be avoided unless specifically prescribed. Alcohol does not directly block the medicine, but heavy alcohol use may worsen liver strain, mood changes, and sexual health problems. Tell your healthcare provider about all prescription drugs, over-the-counter products, vitamins, and supplements you use, including bodybuilding products and herbal testosterone boosters.
Common side effects include acne or oily skin, injection site pain, mild swelling, mood changes, increased sex drive, headache, and changes in sleep. Common lab changes include higher red blood cell counts, changes in cholesterol, and changes in liver tests. Some men may notice breast tenderness, reduced fertility, testicle shrinkage, or worsening male pattern hair loss. Serious side effects can include blood clots, chest pain, shortness of breath, stroke symptoms, severe swelling, worsening sleep apnea, high blood pressure, and serious mood changes such as irritability, aggression, depression, or suicidal thoughts. Testosterone may also increase prostate-related symptoms such as trouble urinating and may raise prostate-specific antigen levels. Contact your healthcare provider right away for leg swelling, sudden shortness of breath, severe headache, yellowing of the skin or eyes, or an allergic reaction such as rash, hives, or swelling of the face or throat.
Store at controlled room temperature, generally 68-77 degrees F (20-25 degrees C), unless your pharmacist gives different instructions. Keep in the original carton to protect from light. Do not freeze. Protect from excessive heat and moisture, and do not store in a bathroom or near a sink. If the solution looks cloudy, has particles, or has changed color, do not use it and contact the pharmacy. Keep out of reach of children and pets. Used needles and syringes must be placed in an approved sharps container. Dispose of expired or unused medication through a pharmacy take-back program when available.

Do not give yourself extra medicine to make up for a missed dose. Contact your healthcare provider or pharmacist for advice on when to take the next dose.

Yes. Your provider will usually check testosterone levels, blood counts, liver tests, and may also monitor prostate health, cholesterol, and blood pressure. These tests help make sure the medicine is working safely.

Yes. Testosterone can lower sperm production and may reduce fertility, sometimes significantly. If you want to have children now or in the future, talk with your healthcare provider before starting treatment.

Can women or children use testosterone cypionate?
This product is generally not used in women, especially during pregnancy or breastfeeding, because it can harm a baby. Children should only use testosterone if a specialist prescribes it and closely monitors growth and development.
