Is testosterone a steroid? Yes. Testosterone is the body’s main androgen, a steroid hormone made mostly in the testicles, and every anabolic steroid on the market is a manufactured version of it. It is also a controlled substance. As of September 2026, federal law lists testosterone in Schedule III of the Controlled Substances Act, the same schedule as ketamine and Tylenol with codeine. This page explains both answers, why the law treats a natural hormone this way, and what shifted in 2025 and 2026.
Quick answer: Testosterone is a steroid hormone and the parent compound of all anabolic steroids. It is unrelated in use to corticosteroids such as prednisone. In the United States it is a Schedule III controlled substance, so it is legal only with a valid prescription. As of September 30, 2026, the DEA still lists it in Schedule III, despite a 2025 FDA expert panel that urged a change.
Is testosterone a steroid? Yes, and here is which kind
“Steroid” describes a chemical family before it describes a drug. Britannica groups testosterone with the other steroid hormones and calls it an androgen, or male hormone. It is made by the testicles, by the ovaries in smaller amounts, and in small amounts by the adrenal glands in both sexes.
The confusion starts with the word itself. Most people hear “steroid” and picture one of two very different things: a bodybuilder’s syringe or a prednisone taper for poison oak.
Those are separate drug families. Cleveland Clinic describes anabolic steroids as manufactured forms of testosterone that work by switching on androgen receptors, while corticosteroids resemble cortisol and are used to calm inflammation and the immune system. A man on prednisone for asthma is taking a steroid. He is not taking an anabolic one.
How federal law defines an anabolic steroid
The legal definition is narrow and useful. Under the Anabolic Steroid Control Act of 2004, as summarized by the DEA in the Federal Register, a substance counts as an anabolic steroid if it is chemically and pharmacologically related to testosterone and is not an estrogen, a progestin, a corticosteroid or DHEA. Testosterone sits at the center of that definition. Everything else is measured against it.
So the plain answer to “is testosterone an anabolic steroid” is yes. It is the original one.
Is testosterone a controlled substance?
Yes. The DEA’s drug scheduling page defines Schedule III drugs as those with “a moderate to low potential for physical and psychological dependence,” and its examples are products with less than 90 milligrams of codeine per dosage unit, ketamine, anabolic steroids and testosterone. The DEA Diversion Control Division’s schedules list names “anabolic steroids such as Depo-Testosterone” in the same group.
Last verified: September 30, 2026. On that date the DEA still listed testosterone in Schedule III, and we found no final DEA rule changing that. Scheduling news moves quickly, so check the DEA page if you are reading this later.
Schedule III sits in the middle of the five federal schedules. The DEA Diversion Control Division describes it as covering substances with less potential for abuse than Schedules I and II, where misuse may lead to moderate or low physical dependence or high psychological dependence. Middle of the ladder.
Why is testosterone a controlled substance?
Congress put it there, against the advice of the American Medical Association. The Anabolic Steroids Control Act of 1990 took effect on February 27, 1991, and placed anabolic steroids, testosterone included, in Schedule III as a class.
The push came from sports and schools. A 1998 review in The Elder Law Journal by Jeffrey Hedges quotes the congressional record: lawmakers cited a 1988 study in which 6.6% of twelfth-grade males had tried steroids, and then-Senator Biden said steroid abuse among male high school students was “nearly as widespread as the use of crack cocaine.” The same review reports that the American Medical Association opposed scheduling, arguing that steroids had accepted medical uses and that their misuse did not produce the kind of dependence the Act requires, and that the FDA and the National Institute on Drug Abuse did not recommend control under the Act.
Our read is simple.
Testosterone became a controlled substance because of how athletes and teenagers were misusing anabolic steroids, and a man with a diagnosed deficiency inherited the rules written for that problem. That is not a fringe view. At the FDA’s December 10, 2025 expert panel, urologist Landon Trost, MD, described the classification as political rather than scientific and said Schedule III “creates barriers to care, both discouraging physicians from prescribing testosterone as well as dissuading patients from asking for it.”
None of this means misuse is harmless. Cleveland Clinic notes that nonmedical users often take doses 10 to 100 times higher than prescribed doses, with risks that include heart attack, stroke and liver damage, and it estimates that 3 to 4 million people in the United States use anabolic steroids for nonmedical purposes. The medical dose and the gym dose are different exposures. Our guide to TRT benefits, risks and delivery methods covers the medical side.
What Schedule III means if your doctor prescribes it
For a patient, scheduling shows up as paperwork and limits. Refills are capped by federal rule: under 21 CFR 1306.22, a Schedule III or IV prescription cannot be filled more than six months after it was written, or refilled more than five times.
That is why testosterone prescriptions renew on a schedule, and why lapses in follow-up can mean a lapse in the medication.
Telehealth is the other piece. The DEA’s fourth temporary extension lets DEA-registered practitioners prescribe Schedule II through V drugs by telemedicine without a prior in-person exam, effective January 1 through December 31, 2026. What replaces it in 2027 was still unsettled when we checked, and anyone getting testosterone only through a telehealth service should ask that service what its plan is.
States keep their own schedules too, and they do not always match federal law automatically. California’s AB 1778, chaptered on August 24, 2026, is one example: if testosterone is ever removed from federal Schedule III or moved to a lower schedule, California will follow without a new vote.
Is testosterone legal or illegal?
Both. It depends on how you got it. Testosterone is legal to use when a licensed practitioner prescribes it and a pharmacy dispenses it. Without that, possession is a federal offense. The Controlled Substances Act at 21 U.S.C. 844 makes it unlawful to possess a controlled substance unless it was obtained directly or through a valid prescription from a practitioner, and a first simple-possession conviction carries up to one year in prison, a minimum fine of $1,000, or both.
Travel, shared vials and “a friend’s leftover prescription” all fall on the wrong side of that line. A prescription covers the person named on it.
Can you buy testosterone over the counter?
No. Testosterone itself is prescription-only in the United States. The products on store shelves labeled “testosterone boosters” or “T support” are sold as dietary supplements. Testosterone is not a legal supplement ingredient.
Some do anyway. In May 2022 the FDA warned consumers about bodybuilding products containing hidden steroids or steroid-like substances, saying many were “illegally marketed unapproved new drugs” and linking them to serious liver injury, kidney damage, heart attack and stroke. A product that promises steroid results without a prescription is either weaker than it claims or riskier than it admits.
Myth: Testosterone is a natural hormone, so it cannot be a steroid.
Fact: Natural and steroid are not opposites. Testosterone is a steroid hormone your body makes, and it is the compound that all anabolic steroids are built from.
Myth: Controlled means dangerous, so a prescription is a red flag.
Fact: Schedule III includes Tylenol with codeine. The listing reflects a 1990 law about misuse, and an FDA panel in 2025 argued it no longer fits prescribed testosterone.
Myth: The FDA made testosterone uncontrolled in 2026.
Fact: The FDA changed label language in 2026. As of September 30, 2026, the DEA still lists testosterone in Schedule III.
What changed in 2025 and 2026, and what did not
It is easy to mix up label changes with scheduling changes. They are separate processes. Here is the sequence from the primary sources.
| Date | What happened | Did it change scheduling? |
|---|---|---|
| December 10, 2025 | FDA expert panel on testosterone therapy in men; panelists urged the agency to stop treating testosterone as a controlled substance | No. A recommendation only |
| April 20, 2026 | FDA Federal Register notice inviting makers to seek a new indication for low libido in men with idiopathic hypogonadism | No |
| June 18, 2026 | HHS and FDA request three label updates for testosterone products | No |
| August 24, 2026 | California AB 1778 chaptered, tying state scheduling to any future federal change | No. Takes effect only if federal law changes |
| September 30, 2026 | DEA scheduling pages still list testosterone in Schedule III | Current status |
The June label request is the biggest concrete change so far. According to the HHS announcement, the FDA asked manufacturers to remove the statement that safety and effectiveness in age-related hypogonadism have not been established, to narrow the prostate cancer contraindication to metastatic prostate cancer, and to revise the benign prostatic hyperplasia warning, citing the TRAVERSE trial of more than 5,200 men. The April Federal Register notice does not mention scheduling at all.
Will the DEA follow the panel? Nobody outside the agency can say yet, and a change to a category that Congress created by statute in 1990 may take more than a panel’s vote.

Frequently asked questions
Is testosterone a steroid or a hormone?
It is both. Testosterone is a steroid hormone, and reference sources such as Britannica group it with the other steroid hormones. It is the main male androgen and the compound all anabolic steroids are derived from. It is unrelated in use to corticosteroids such as prednisone, which resemble cortisol and are prescribed to reduce inflammation.
What schedule is testosterone?
Testosterone is a Schedule III controlled substance under the federal Controlled Substances Act. It was placed there as part of the anabolic steroid class by the Anabolic Steroids Control Act of 1990, effective February 27, 1991. As of September 30, 2026, the DEA still lists it in Schedule III.
Why is testosterone a controlled substance?
Congress scheduled anabolic steroids, including testosterone, in 1990 after concern about misuse by athletes and high school students. According to a review of the congressional record, the American Medical Association opposed the move, and the FDA and National Institute on Drug Abuse did not recommend it. The listing reflects misuse, not a finding about prescribed doses.
Is it illegal to have testosterone without a prescription?
Yes. Federal law makes it unlawful to possess a controlled substance unless it was obtained directly or through a valid prescription from a practitioner. A first simple-possession conviction can bring up to one year in prison and a minimum $1,000 fine. A prescription covers only the person it was written for.
Can you buy testosterone over the counter?
No. Testosterone is prescription-only in the United States. Over-the-counter “testosterone boosters” are sold as dietary supplements, and testosterone is not a legal supplement ingredient. The FDA has warned that some bodybuilding products hide steroids or steroid-like ingredients and has linked them to serious liver injury, kidney damage, heart attack and stroke.
