Why testosterone is a Schedule III controlled substance
If you're prescribed testosterone, you may have seen "controlled substance" on a pharmacy label, been told a refill needs a new prescription, or been asked about it before a trip. This guide explains, from federal sources, what the Schedule III listing is, where it came from, what it means for a prescription, and which records are worth keeping. Sources checked November 2, 2026.
It explains federal rules in plain terms. It's a summary of DEA's published guidance and the regulations, not legal advice, and it doesn't say whether any treatment is right for you. Your pharmacist can tell you how the rules apply to your prescription, and your state's rules may add to them.
The short answer
Yes, testosterone is a controlled substance in the US. The label:
Schedule III controlled substance · prescription only
Federal regulations name testosterone among the anabolic steroids in Schedule III (21 CFR 1308.13(f), item 84). DEA's Controlled Substance Schedules page lists anabolic steroids among its Schedule III non-narcotic examples, with a testosterone product, Depo-Testosterone, as its example. Federally it's Schedule III, not Schedule I, II or IV.
What the schedules are
The federal Controlled Substances Act sorts controlled substances into five schedules, I to V. DEA describes each one by whether its substances have an accepted medical use in the US and by their potential for abuse and dependence. For Schedule III, DEA says the substances have a "potential for abuse less than substances in Schedules I or II," and that misuse may lead to moderate or low physical dependence or high psychological dependence.
A schedule describes how a substance is regulated: who may prescribe and dispense it, and the rules for prescriptions and records. It isn't a measure of whether a medicine works, and it isn't a verdict on anyone who's prescribed it.
How testosterone came to be listed
- 1990. The Anabolic Steroids Control Act of 1990 was enacted on November 29, 1990, as Title XIX of Public Law 101-647. It added "Anabolic steroids" as a new item at the end of Schedule III in the Controlled Substances Act (21 U.S.C. 812(c)), taking effect 90 days after enactment.
- 2004. The Anabolic Steroid Control Act of 2004 (Public Law 108-358, approved October 22, 2004) replaced the law's definition of "anabolic steroid" (21 U.S.C. 802(41)). It now begins "any drug or hormonal substance, chemically and pharmacologically related to testosterone", with some exceptions, followed by a list of named substances that includes testosterone itself.
- The regulation today. DEA's regulations list the anabolic steroids in Schedule III at 21 CFR 1308.13(f). The listing covers "any material, compound, mixture or preparation containing any quantity" of the named substances, "including its salts, esters and ethers". Testosterone is item (84).
So the listing is about the substance, not one product. It covers preparations that contain testosterone, whatever their form. Product labels say so too: the AndroGel label on DailyMed shows its DEA schedule as CIII, and its section 9.1 says the product "contains testosterone, a Schedule III controlled substance".
What it means for a prescription
How it can be prescribed
Under 21 CFR 1306.21(a), a pharmacist may dispense a Schedule III, IV or V controlled substance only under one of these:
- a paper prescription signed by the practitioner;
- a fax of a signed paper prescription, sent by the practitioner or the practitioner's agent to the pharmacy;
- an electronic prescription that meets DEA's requirements for one;
- an oral (call-in) prescription from the practitioner, which the pharmacist promptly puts in writing.
DEA's manual for pharmacists adds that, to be valid, a prescription for a controlled substance must be issued for a legitimate medical purpose by a practitioner acting in the usual course of professional practice.
Refills
A Schedule III prescription can be refilled only if the prescription authorizes refills. 21 CFR 1306.22(a) sets two limits: it can't be filled or refilled more than six months after the date it was issued, and it can't be refilled more than five times. DEA's manual puts it plainly: after five refills or six months, whichever comes first, a new prescription is needed.
That's why the date the prescription was issued matters, not only the date you first filled it.
Moving a prescription to another pharmacy
Under 21 CFR 1306.25(a), the original prescription information for a Schedule III, IV or V substance can be transferred between pharmacies for refills "on a one-time basis only". Pharmacies that share a real-time, online database may transfer up to the maximum refills permitted by law and the prescriber's authorization. DEA's manual adds that an original prescription received on paper, by fax or orally can't be transferred before it's filled; after it's filled, the refills can be. The two pharmacists handle the transfer between them, so ask your pharmacy how it works for yours.
State rules
DEA's manual says federal controlled-substance laws "are designed to function in tandem with state controlled substance laws." Your state's rules apply as well as the federal ones, and they can be stricter. This guide doesn't list state rules: your pharmacist can tell you which ones apply to you.
Compounded testosterone
FDA approval and DEA scheduling are separate things. Approval belongs to a specific product, for the uses, form and route on its label. FDA says "compounded drugs are not FDA-approved," and that it doesn't verify their safety, effectiveness or quality before they're marketed. So a compounded testosterone cream or other compounded preparation isn't one of the approved products and doesn't share their approval, even though it contains the same active ingredient.
Scheduling follows the substance. The Schedule III listing covers preparations containing testosterone, so it applies to compounded testosterone as well. The testosterone page lists the FDA-approved testosterone products by route, with sources and check dates, and what FDA approved, investigational and compounded mean explains the terms.
What it doesn't mean
- It isn't a ban. Schedule III substances have an accepted medical use, and they're dispensed under a valid prescription.
- It isn't a judgement on your treatment. The schedule is about how the substance is regulated, not about you or the reasons it was prescribed.
- It doesn't make one product approved. Scheduling and FDA approval answer different questions (see above).
Records worth keeping
Because refills run against the prescription's issue date and a count, a few details are worth keeping in one place. Most of them are on the pharmacy label or paperwork, so a photo of each new label is an easy start.
- The prescription: the date it was issued, the prescriber's name and how to reach them, and the number of refills it authorizes.
- Each fill: the date, the pharmacy's name and phone number, the prescription (Rx) number, and the refills remaining as printed on the label.
- A transfer: the date, and which pharmacy it moved from and to.
- The product: its name, form and route as printed on the label, so your log matches what you were dispensed.
- What you took, as you entered it: each dose with its date and time, the route and, for an injection, the site. Record what you actually did, including a dose you didn't take.
- Anything unusual: if a supply is lost or stolen, tell your pharmacist and prescriber, and note the date and who you told.
Bring these to appointments (what to bring to an appointment) and keep a copy before you travel (traveling with testosterone).
How Peptimes helps
Peptimes is a private iPhone tracker for the compounds you already use, testosterone included. In the Library, testosterone entries show "DEA Schedule: Schedule III · Controlled substance · prescription only". No other Library entry names a DEA schedule.
You enter your own amounts and schedules, and Peptimes never suggests an amount. Log a Dose records the amount you entered, the route, the injection site when it's injected, and how you feel. Each dose has a Notes field, "Anything else you want to remember?", for something like the product name on your label. Dose History lists every dose newest first, with search and a chip for each compound, and Home and the Calendar let you mark a dose as not taken.
Your health records are stored on your iPhone, and Peptimes doesn't keep a copy of your records on its servers. Export your records as CSV or JSON, for yourself or an appointment: share your medication log with your doctor has the steps. Keep the prescription and pharmacy details above with your pharmacy paperwork or alongside your export. See how Peptimes works as a TRT tracker. Peptimes is a tracking app. We don't sell peptides.
