TRT California: Who Can Prescribe and the State Rules

How It Works

How TRT in California Actually Works

TRT in California works by video for most men, and the order of the steps matters more than the setting. A clinician authorized to treat a patient located in California takes a history, orders bloodwork, reads it, and writes for testosterone only when the labs and the symptoms agree. That sequence separates a medical practice from a storefront:

A symptom history first. Fatigue, low sex drive and slow recovery bring most men in, and each has explanations unrelated to testosterone.
Fasting morning bloodwork, drawn twice. The Endocrine Society guideline recommends a fasting morning total testosterone as the initial test, confirmed on a second morning before any diagnosis (PMID 29562364).
A prescription written against the numbers, with a documented reason to treat or not to.
Repeat panels on a calendar. Hematocrit, PSA and estradiol all move once treatment starts.

Protocol Health runs TRT for men in that order for California patients, by video and by mail, with blood drawn at a lab near you. There is no Protocol Health office in California, so every step happens remotely apart from the blood draw.

Who Can Prescribe

Who Can Legally Prescribe TRT in California?

Only a clinician licensed in California may legally prescribe TRT to a patient located in California. The Medical Board of California puts it without hedging: physicians using telehealth to treat patients located in California must be licensed in California, though they need not live here. Prescribing without a license is a public offense under Business and Professions Code 2052.

California offers no side door, and this is where it parts company with Florida. Florida lets an out-of-state clinician register as a telehealth provider and prescribe without a Florida license. California has no equivalent registration. Its exceptions to the license requirement are narrow and none of them fits routine hormone care: Business and Professions Code 2052.5 reaches only patients with an immediately life-threatening condition, and Business and Professions Code 2060 exempts an out-of-state practitioner only when in actual consultation with a practitioner licensed in California, and bars that practitioner from giving orders or holding ultimate authority over a patient located here, which leaves the California licensee as the prescriber either way. What the license must match is where you are sitting, whether Los Angeles, San Diego, Sacramento or the Bay Area, so a practice with no California office can still be the right one to prescribe TRT to you.

Schedule III

Testosterone Is Schedule III, and California Lists It by Name

Testosterone is a Schedule III controlled substance, and California lists it by name rather than leaving it to the federal schedules. Health and Safety Code 11056 sets out California's Schedule III, and subdivision (f), covering anabolic steroids, names testosterone at paragraph (30). The federal Anabolic Steroids Control Act of 1990 had already placed anabolic steroids in federal Schedule III, so a California testosterone prescription sits inside Schedule III twice over.

Two things follow. Buying testosterone without a prescription is a controlled-substance offense in California, and every lawful route runs through an accountable prescriber. The scheduling also decides what reaches you next: because testosterone is Schedule III rather than Schedule II, the Schedule II telehealth bars some states impose, of which Florida's under Statute 456.47 is the clearest, do not reach it, while the Schedule III database duty below does.

Exam or Video

Do You Need an In-Person Exam to Start TRT in California?

You do not need an in-person exam to start TRT in California, but you do need a real examination, and one statute says both. Business and Professions Code 2242 makes it unprofessional conduct to prescribe dangerous drugs "without an appropriate prior examination and a medical indication." Its next sentence settles the telehealth question: an appropriate prior examination "does not require a synchronous interaction between the patient and the licensee and can be achieved through the use of telehealth, including, but not limited to, a self-screening tool or a questionnaire, provided that the licensee complies with the appropriate standard of care."

That proviso does the real work. California permits the questionnaire; it does not excuse the standard of care, which the Medical Board of California states is the same by telehealth as in person. California also has no anabolic-steroid rule of the kind New Jersey applies, where a board regulation demands a full physical examination before testosterone. Consent is the remaining state step: Business and Professions Code 2290.5 requires the provider to obtain the patient's verbal or written consent to telehealth and to document it.

One federal layer sits above it, identical in every state. The Ryan Haight Act normally requires an in-person evaluation before a controlled substance is prescribed, and telemedicine is the exception. The DEA and the Department of Health and Human Services have currently extended those flexibilities through December 31, 2026. As of October 2026 that extension is what permits a first testosterone prescription in California without an in-person visit, so ask any clinic what happens after it.

CURES

CURES: The Database Your California Prescriber Must Check

CURES is the California database your prescriber must check, and in 2026 it stopped recording the one drug this page is about. CURES is the state's prescription drug monitoring program, run by the Department of Justice, and Health and Safety Code 11165.1 requires every California practitioner authorized to prescribe Schedule II through V drugs to register for access once they hold a DEA certificate.

The duty is specific. Health and Safety Code 11165.4 requires a prescriber to review the patient's controlled-substance history for the previous twelve months before prescribing a Schedule II, III or IV drug for the first time, and at least once every six months after that if the prescriber renews the prescription and testosterone remains part of the treatment. Testosterone is Schedule III here, so a TRT prescription falls inside that duty, subject to narrow exemptions including a single nonrefillable seven-day supply, surgical and emergency settings, and occasions when CURES is not operational.

Here is the part that changes the picture, and that none of the three pages ranking for this search mentions. Health and Safety Code 11165, subdivision (k)(1), now provides that "a prescription for or the dispensing of testosterone or mifepristone shall not be reported to the department, CURES, or a contracted prescription data processing vendor." That provision became operative on 1 January 2026, and the Department of Justice must purge earlier testosterone records by 1 January 2027.

Be careful what you conclude, because the two rules do different jobs. Reporting testosterone into CURES is now barred, so a CURES check will no longer show a patient's testosterone history. That is not the same as the consultation duty disappearing. Section 11165.4 still stands, and AB 82 did not touch it. The practical effect is that the database your prescriber must still check has been made deliberately blind to testosterone itself.

Risks

The Risks Worth Weighing Before You Start TRT

The risks worth weighing before you start TRT belong in the same conversation as the reasons to want it. A prescriber who cannot name them unprompted is the wrong prescriber.

Fertility. Testosterone from outside suppresses the body's own production, and sperm counts can fall with it. The Endocrine Society guideline recommends against starting testosterone in men planning fertility in the near term. Enclomiphene, which is not FDA-approved for any use, acts on the same feedback loop rather than replacing the hormone; whether it fits is a decision for the treating clinician.
Hematocrit. Testosterone raises red cell mass, and the Endocrine Society guideline directs clinicians to measure hematocrit as part of standard monitoring. Our guide to lowering hematocrit on TRT sets out the monitoring.
Prostate. PSA is tracked throughout. The guideline recommends against starting testosterone in men with prostate cancer, a palpable nodule or induration, or a PSA above 4 ng/mL, and above 3 ng/mL at increased risk, without urological evaluation.
Conditions that rule it out. The same guideline recommends against starting testosterone in men with breast cancer, an elevated hematocrit, untreated severe obstructive sleep apnea, severe lower urinary tract symptoms, uncontrolled heart failure, a heart attack or stroke in the previous six months, or thrombophilia.
Cardiovascular safety. The TRAVERSE trial randomized 5,246 men aged 45 to 80 with hypogonadism and existing or high cardiovascular risk to transdermal testosterone or placebo. A major adverse cardiac event occurred in 7.0% on testosterone and 7.3% on placebo, meeting the noninferiority margin. The trial recorded a higher incidence of atrial fibrillation, acute kidney injury and pulmonary embolism on testosterone (NEJM 2023).

None of that argues against treatment. It argues for a prescriber who measures, and for treating the monitoring panel as therapy rather than an upsell, which is how these risks are managed.

Our Approach

TRT at Protocol Health: California by Telehealth, Scarsdale in Person

TRT at Protocol Health reaches California by telehealth, and Scarsdale is the only place we see anyone in person. Protocol Health is a physician-led longevity practice in Scarsdale, New York, treating patients in person there and by telehealth in New York, New Jersey, Connecticut, Florida and California. There is no office in California.

Protocol Health prescribes testosterone therapy, anastrozole alongside it where estradiol management is clinically warranted, and enclomiphene. We have a commercial interest here and say so, which is why this page rests on the California statutes and the Medical Board's own guidance. Three points of regulatory status:

Testosterone cypionate, enanthate and undecanoate injections are FDA-approved drugs; compounded testosterone preparations are not FDA-approved. Prescribing them for age-related low testosterone is an off-label use.
Anastrozole is an approved drug. Using it alongside TRT in men is also off-label, is not routine, and is decided with the prescriber holding your estradiol results.
Enclomiphene is unapproved, meaning not FDA-approved for any use. We prescribe enclomiphene rather than Clomid.

The treating clinician decides whether testosterone is appropriate, in which form and at what dose, against your labs and history. This page sets no dose and gives no individual advice. Start with the two-minute health quiz, or see what advanced lab testing covers. TRT at Protocol Health runs end to end by telehealth for California patients, and Scarsdale stays the only room we meet anyone in person.

FAQ

Frequently Asked Questions

Is TRT legal in California?

Yes, with a prescription from a clinician licensed in California. California lists testosterone by name in its own Schedule III at Health and Safety Code 11056(f)(30), so buying and self-injecting it without a prescription is an offense. What governs is where the patient is located, not where the clinic keeps an office.

Is testosterone a controlled substance in California?

Yes, in Schedule III. Health and Safety Code 11056 places anabolic steroids in California's Schedule III and names testosterone at subdivision (f)(30). The federal Anabolic Steroids Control Act of 1990 placed anabolic steroids in federal Schedule III, so the state and federal classifications agree.

Can you get TRT through telehealth in California?

Yes, when the prescriber holds a California license, because the patient's location governs rather than the clinic's address. California has no out-of-state telehealth registration of the kind Florida offers under Statute 456.47, so a clinician without a California license cannot lawfully prescribe to you here.

Do you need an in-person exam to start TRT in California?

No. Business and Professions Code 2242 requires an appropriate prior examination and a medical indication, and the same section states that examination can be achieved through telehealth, including a self-screening tool or questionnaire, provided the licensee complies with the appropriate standard of care. Unlike New Jersey, California has no anabolic-steroid rule requiring a physical examination first.

Does a California TRT prescription show up in CURES?

No, not since 2026. Health and Safety Code 11165(k)(1) provides that a prescription for or the dispensing of testosterone shall not be reported to CURES, operative 1 January 2026, and the Department of Justice must purge earlier testosterone records by 1 January 2027. The separate duty on prescribers to consult CURES before writing a Schedule III drug is not repealed by it.

Does Protocol Health have a clinic in California?

No. Protocol Health's only in-person clinic is in Scarsdale, New York. California patients are treated by telehealth, with labs drawn near home and medication shipped.
