    The Nexphoria clinical standard

    Asked plainly, answered plainly

    Is Testosterone Cypionate FDA-approved?

    Compounded Testosterone Cypionate is prepared for you by a licensed 503A pharmacy under a physician's prescription, and compounded medications are not FDA-approved. Where a branded, FDA-approved version of the active ingredient exists, that approval does not extend to the compounded preparation. Compounded medications are not evaluated by the FDA for safety, effectiveness, or quality.

    Do I need a prescription?

    Yes. A licensed U.S. physician reviews your health questions and writes the prescription if it is right for you. Everything happens online.

    What bloodwork is required?

    A free at-home blood kit ships with your first order, so your physician sets your Testosterone Cypionate dose against your numbers. At week 12, the same full panel is drawn again, included, and your dose is adjusted from what changed.

    What should I expect in the first weeks?

    Wk 1: Your first dose. Everyone responds differently, which is why your blood panel at week 12 is part of the plan and your dose is adjusted from it.

    How is it billed?

    You buy a block of time, paid up front: one month to try it, or three, six or twelve months at 10, 15 or 20% less per month. Longer terms include more blood work. When your term ends, renewing is your choice.

    Your week-12 blood panel

    See how your body is responding.

    Testosterone is dosed against a number, so your baseline panel matters most here. Your physician sets your dose from your total and free testosterone, then reads testosterone, estradiol and red blood cell count at week 12 to adjust it.

    A full panel of 24 markers is included in your plan. See every marker and why it is there

    What your physician checks first

    Total testosterone · Free testosterone · Estradiol · Hematocrit · PSA · LH and FSH

    Your dose is set against your Total testosterone.

    Your physician checks for

    • Prostate or breast cancer
    • Untreated sleep apnea
    • Plans to conceive
    • High red blood cell count

    More than the medication

    Your medication, your physician, and the blood panel behind it.

    Compounded preparations are not FDA-approved, and the FDA does not review them for safety or effectiveness. Where an active ingredient is FDA-approved in other products, that approval does not extend to a compounded preparation. Prescribed only where a licensed provider determines it appropriate.
