Testosterone

Bioidentical testosterone for hormone optimization.

What it does

What Testosterone is and why doctors prescribe it.

Testosterone is the primary androgen in men and is also clinically relevant at lower physiological levels in women. In compounded HRT it's prescribed for hypogonadism (clinically low testosterone) in men, for select female patients with low-libido or hormonal-imbalance presentations the doctor identifies, and where manufactured products don't fit the patient's clinical needs (excipient sensitivity, dose precision, route).

How it works

Mechanism in plain English.

Testosterone binds the androgen receptor in muscle, bone, brain, and reproductive tissues. Compounded preparations include injectable esters (cypionate, enanthate) for sustained-release IM/SC dosing, topical creams and gels for daily transdermal delivery, and lower-strength female-dosed creams. The dosage form is chosen to match the patient's pharmacokinetic needs.

How long it's been studied

Research history.

Testosterone has been studied as an isolated steroid since the 1930s (synthesis, 1935). Modern guidelines from the Endocrine Society inform diagnosis and prescribing. Compounded testosterone is dispensed under 503A on a patient-specific prescription; injectable esters and topical preparations have been compounded for decades.

Dosing

Clinical context for the prescribing doctor.

Doctor-prescribed and lab-monitored. Male hypogonadism injectable testosterone cypionate or enanthate is commonly prescribed in the 50–200 mg per week range; topical creams use a different strength schedule; female dosing is much lower (typically a tenth of male dosing). Your doctor monitors total and free testosterone, hematocrit, PSA where indicated, and lipid markers, and titrates dose to clinical and lab targets.

This page is informational, not a dispensing aid. Testosterone is dispensed only on a patient-specific prescription written by a licensed doctor for an identified patient. Compounded drugs are not FDA-approved and should not be evaluated using branded-drug trial data. Availability varies by state and prescribed medication.
