Testosterone Cypionate
Injectable testosterone is one of several ways to administer testosterone replacement therapy. It may be an option for patients who prefer a prescribed dosing schedule instead of daily topical application.
*Prescription required. Results may vary. For additional information, see product information.
Typically administered via intramuscular injection (e.g. gluteal muscle) at a frequency and dose prescribed by your provider—often weekly or every other week at low doses for women.
Testosterone therapy is a clinical treatment that requires medical supervision to mitigate risks. Potential side effects are primarily managed through proper dosing and regular blood work.
Known side effects can include an increase in red blood cell count (erythrocytosis), which can increase blood viscosity; suppression of natural sperm production; and potential acne or oily skin.
Regular monitoring of your hematocrit and other key markers is a mandatory part of our protocol to ensure your safety.
You are encouraged to report negative side effects of prescription products:

Important Safety Information
Important Safety Information — Compounded Testosterone
What is this?
This Important Safety Information summarizes key warnings, precautions, contraindications, and possible side effects for compounded testosterone, a prescription medication used in certain patients when a licensed healthcare provider determines that testosterone therapy is medically appropriate.
This page does not include all possible information about compounded testosterone. Always follow your prescription label, pharmacy instructions, and the instructions provided by your ATHS healthcare provider.
Compounded testosterone is not FDA-approved. The FDA does not review compounded medications for safety, effectiveness, or quality before they are dispensed. Compounded medications may be prescribed when a licensed healthcare provider determines that a compounded preparation is medically appropriate for a specific patient.
Testosterone is a Schedule III controlled substance. Use only as prescribed.
Safety and effectiveness of testosterone therapy have not been established for men with age-related hypogonadism, sometimes referred to as late-onset hypogonadism. Your provider will determine whether testosterone therapy is medically appropriate based on your symptoms, medical history, physical risk factors, and laboratory results.
Important Warnings and Precautions
Compounded testosterone may cause or worsen serious medical problems, including:
- Increased blood pressure, which may require monitoring and treatment and may increase cardiovascular risk over time.
- Blood clots, including deep vein thrombosis and pulmonary embolism.
- Fluid retention or edema, which may be serious in patients with heart, kidney, or liver disease.
- Increased red blood cell count, also called polycythemia.
- Worsening of enlarged prostate symptoms or urinary obstruction.
- Growth or worsening of known or suspected prostate cancer.
- Suppression of sperm production, which may reduce fertility.
- Gynecomastia, or breast tissue enlargement.
- Hypercalcemia, especially in immobilized patients.
- Allergic or hypersensitivity reactions, including reactions to testosterone, carrier oils, preservatives, or other ingredients in the compounded medication.
- Serious psychiatric, cardiovascular, liver, reproductive, and withdrawal-related risks when testosterone is abused, misused, or taken at doses higher than prescribed.
Seek emergency medical care if you experience chest pain, sudden shortness of breath, symptoms of stroke, swelling or pain in one leg, sudden vision changes, severe allergic reaction, or a prolonged erection lasting more than four hours.
Who Should Not Use Compounded Testosterone?
Do not use compounded testosterone if you:
- Are allergic to testosterone or any ingredient in the compounded medication.

- Vision problems, including central serous chorioretinopathy.
- Any history of allergic reaction to testosterone, hormone therapy, injections, oils, preservatives, or compounded medications.
Also tell your provider about all prescription medications, over-the-counter medications, supplements, hormones, peptides, anabolic steroids, fertility medications, and performance-enhancing substances you use or have recently used.
Compounded Formulation and Allergy Information
Compounded injectable testosterone may be prepared in a carrier oil, which may include cottonseed oil, sesame oil, grapeseed oil, MCT oil, or another vehicle selected by the dispensing pharmacy. Some preparations may contain benzyl alcohol, benzyl benzoate, or other inactive ingredients.
Tell your provider and pharmacist if you have allergies or sensitivities to seeds, nuts, oils, preservatives, benzyl alcohol, benzyl benzoate, or any prior reaction to an oil-based injection. Severe hypersensitivity reactions, including anaphylactoid reactions, have been reported with testosterone products.
If your compounded medication contains benzyl alcohol, tell your provider if you are pregnant, may become pregnant, or are breastfeeding. Benzyl alcohol can cross the placenta.
Drug Interactions
Compounded testosterone may interact with other medications.
Tell your provider if you take:
- Blood thinners or oral anticoagulants.
- Insulin or diabetes medications.
- Corticosteroids.
- Medications that affect blood pressure.
- Other hormone therapies.
- Anabolic steroids.
- Fertility medications such as hCG, clomiphene, or enclomiphene.
- Supplements marketed for testosterone, libido, muscle growth, or performance.
Testosterone may increase sensitivity to oral anticoagulants. Patients using anticoagulants may require closer monitoring of prothrombin time or INR and possible anticoagulant dose adjustment by their healthcare provider.
In patients with diabetes, testosterone may affect blood glucose and could change insulin or diabetes medication requirements.
Monitoring During Treatment
Your provider may require periodic lab testing and follow-up visits while you are using compounded testosterone.
Monitoring may include:
- Total testosterone.
- Free testosterone.
- Hemoglobin and hematocrit.
- PSA, when clinically appropriate.
- Liver-related labs, when clinically appropriate.
- Lipids, including HDL cholesterol, when clinically appropriate.
- Blood pressure.
- Estradiol, when clinically appropriate.
- Other labs based on your medical history and treatment plan.
Do not skip recommended lab testing. Testosterone therapy can create risks that may not be obvious without blood work.
Possible Side Effects
Possible side effects of testosterone therapy include:
- Acne or oily skin.
- Increased body or facial hair.
- Male-pattern hair loss.
- Breast tenderness or enlargement.
- Changes in libido.

Contact your provider if side effects are persistent, worsening, or concerning.
Blood Clot Warning
Blood clots have been reported in patients using testosterone products. Symptoms of a blood clot may include:
- Pain, swelling, warmth, or redness in one leg.
- Sudden shortness of breath.
- Chest pain.
- Rapid heartbeat.
- Coughing blood.
- Sudden dizziness or fainting.
Seek emergency medical attention if these symptoms occur.
Cardiovascular and Blood Pressure Warning
Testosterone may increase blood pressure, which can increase cardiovascular risk over time. Your provider may monitor your blood pressure before and during treatment, especially if you have high blood pressure, heart disease, a history of heart attack or stroke, or other
cardiovascular risk factors.
Tell your provider if you have chest pain, shortness of breath, fainting, swelling, rapid weight gain, worsening exercise tolerance, or any new or worsening cardiovascular symptoms.
Seek emergency medical attention if you experience chest pain, sudden shortness of breath, sudden weakness, trouble speaking, sudden vision changes, severe headache, fainting, or symptoms of a heart attack or stroke.
Edema and Fluid Retention Warning
Testosterone may cause retention of sodium, chloride, water, potassium, calcium, and inorganic phosphates. Edema, with or without congestive heart failure, may be a serious complication in patients with pre-existing heart, kidney, or liver disease.
Tell your provider if you develop swelling of the ankles, feet, or legs; sudden weight gain; shortness of breath; or worsening heart failure symptoms.
Hypercalcemia Warning
Hypercalcemia may occur in immobilized patients using testosterone. Tell your provider if you are immobilized due to surgery, hospitalization, fracture, serious illness, or prolonged bed rest.
Symptoms of high calcium may include nausea, vomiting, constipation, increased thirst, frequent urination, confusion, weakness, or abnormal heart rhythm. If hypercalcemia occurs, testosterone therapy may need to be discontinued.
Prostate and Urinary Warning
Testosterone should not be used in men with known or suspected prostate cancer. Testosterone may also worsen symptoms of benign prostatic hypertrophy, including urinary obstruction.
Tell your provider if you experience:
- Difficulty urinating.
- Weak urine stream.
- Frequent nighttime urination.
- New or worsening urinary urgency.
- Blood in urine.
- Pelvic pain.
- Elevated PSA.
- History of prostate cancer or suspected prostate cancer.
Older patients treated with testosterone may have an increased risk of developing prostate enlargement and prostate cancer, although conclusive evidence is lacking.
Fertility Warning
Testosterone therapy can suppress the body’s natural testosterone production and may reduce sperm production. This may reduce fertility and may contribute to infertility in some patients.
Tell your provider before starting treatment if you are trying to conceive, plan to have children, or want to preserve fertility.
Hepatic Warning
Serious hepatic complications, including hepatic adenomas, hepatocellular carcinoma, and peliosis hepatis, have been associated principally with prolonged use of high-dose 17-alpha alkyl androgens. Testosterone cypionate is not a 17-alpha alkyl androgen, but liver-related lab changes and rare hepatic complications have been reported with androgen therapy.
Tell your provider if you experience yellowing of the skin or eyes, dark urine, persistent nausea or vomiting, unusual fatigue, abdominal pain, or other symptoms suggestive of liver problems.
Administration and Route of Use
Use compounded testosterone exactly as prescribed. Do not change your dose, frequency, or route of administration unless instructed by your healthcare provider.
If you are prescribed injectable testosterone, follow all instructions provided by your healthcare provider and pharmacy, including instructions for injection technique, storage, handling, and disposal of needles and syringes.
Abuse, Misuse, Dependence, and Withdrawal
Use compounded testosterone only as prescribed.
Testosterone abuse can occur when testosterone is used at higher doses than prescribed, used without medical need, combined with anabolic steroids, or used for bodybuilding or athletic performance enhancement.
Abuse of testosterone and anabolic androgenic steroids has been associated with serious adverse reactions, including cardiac arrest, heart attack, stroke, heart failure, liver injury, depression, mania, paranoia, psychosis, delusions, hallucinations, hostility, aggression, testicular atrophy, subfertility, infertility, and withdrawal symptoms.
Withdrawal symptoms after abrupt discontinuation or significant dose reduction may include depressed mood, major depression, fatigue, craving, restlessness, irritability, loss of appetite, insomnia, decreased libido, and hypogonadotropic hypogonadism.
Do not increase your dose, change your schedule, combine testosterone with anabolic steroids, or continue treatment against medical advice.
