Testosterone cypionate is prescribed for men with confirmed low testosterone (hypogonadism), typically defined as total testosterone below 300 ng/dL combined with symptoms such as fatigue and low energy, reduced libido and sexual dysfunction, loss of muscle mass and increased body fat, depression, irritability, or mood changes, difficulty concentrating or "brain fog," and decreased motivation. A diagnosis requires both low lab values and clinical symptoms. Our providers will review your complete health picture to determine if TRT is appropriate.

Common side effects include injection site soreness or redness, mild acne especially during the first few months, increased red blood cell count (polycythemia), fluid retention, breast tenderness or enlargement (rare), and changes in mood or sleep patterns. More serious risks that require monitoring include elevated hematocrit requiring dose adjustment or blood donation, potential impact on fertility and sperm production, possible effects on prostate health, and cardiovascular considerations in certain populations. Regular monitoring helps identify and address any issues early.

Yes. Testosterone replacement therapy typically suppresses sperm production because external testosterone signals your body to reduce its own production. This can significantly decrease sperm count and may cause temporary infertility. If you're planning to have children, discuss this with your provider. Options include delaying TRT, using enclomiphene instead, or adding HCG to your protocol to maintain testicular function. Fertility typically returns after stopping TRT, though recovery time varies.

We recommend comprehensive lab work before starting TRT, at 6-8 weeks after starting to assess initial response, every 3-6 months during the first year, and annually once stable. Lab panels typically include total and free testosterone, hematocrit and hemoglobin, PSA (prostate-specific antigen), metabolic panel, and estradiol (estrogen). This monitoring ensures your treatment stays safe and effective.

Yes. Testosterone cypionate can travel with you. Keep it in its original prescription packaging with your name on it. For air travel, pack it in your carry-on with a copy of your prescription. Insulin syringes don't require special documentation. If traveling internationally, check the destination country's regulations regarding controlled substances.
