Androstenediol Drug Interactions, Uses, Effectiveness, Safety & More
What is this page for?
First and foremost: how Androstenediol interacts with medications. The heart of this page is the interaction list — every drug Androstenediol is known to interact with, and how serious each one is.
But these pages have grown well beyond that into a full monograph — what Androstenediol is, what people use it for and how strong the evidence is, its safety and side effects, and answers to the questions we’re asked most — written and reviewed by the clinical staff at HelloPharmacist. It’s educational information from our licensed clinical databases, not medical advice, and we don’t sell or endorse products. Our editorial policy

Add one medicationAndrostenediol Drug Interactions: The Bottom Line
From the HelloPharmacist Editorial Team · Updated July 2026Based on the available evidence, the overall risk of a clinically significant Androstenediol drug interaction appears low for most people, though anyone on hormone therapy should be aware of it. No interactions are rated major, and while the listed medications carry a moderate rating, the concerns come from theory rather than documented problems in people.
The interactions that deserve the most attention involve hormone medicines, specifically estrogens and testosterone. Because the body can convert androstenediol into these hormones, there is a concern it could add to their effects and side effects. That said, this conversion mainly happens when the body's own hormone levels are low, which is usually not the case for someone already taking hormone therapy, so the real-world impact may be smaller than it sounds.
Although the number of medications on the list looks large, they all fall into these two hormone groups, and the concern is theoretical rather than proven. We have not seen human evidence that combining androstenediol with these medicines causes meaningful harm, so the moderate rating reflects caution, not confirmed danger.

What Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
- Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From

The kinds of drugs Androstenediol affects
Every type of medication (drug category) Androstenediol is known to interact with. Open any category for the detail — or search your exact drug in the checker above.
Estrogens
Androstenediol is a precursor to estrogen and can increase levels of estradiol and estrone. There is some concern that taking androstenediol with estrogens might increase estrogenic effects and potential side effects. However, androstenediol is converted to estrogen in low estrogen environments. Patients who are taking supplemental estrogen do not have low estrogen levels. Therefore, androstenediol might not be converted to estrogen in these patients. It is unclear how this might alter the effects and side effects of androstenediol. Until more is known, use with caution or avoid using with estrogen-containing drugs. Some of these drugs include CombiPatch, Estraderm Transdermal, Kestrone, Vivelle Transdermal, and others.
Testosterone
Androstenediol is a precursor to testosterone and can increase levels of testosterone. There is some concern that taking androstenediol with testosterone might increase therapeutic and adverse effects of testosterone. However, androstenediol is converted to testosterone in low testosterone environments. Patients taking supplemental testosterone do not have low testosterone levels. Therefore, androstenediol might not be converted to testosterone in these patients. It is unclear how this might alter the effects and side effects of androstenediol. Until more is known, use with caution or avoid using with testosterone-containing drugs. Some of these drugs include Androderm Transdermal, AndroGel, Depo-Testosterone, Testex, Testoderm, and others.
Androstenediol: Uses, Safety & Side Effects
Androstenediol is a prohormone (a precursor the body can convert into testosterone and other hormones) marketed to raise testosterone and build muscle, but solid human evidence for these benefits is lacking and it carries real hormonal risks. In the United States it is a Schedule III controlled substance and is banned in most competitive sports. Talk with a doctor or pharmacist before considering any product containing it.

- Part used
- Not a plant; a steroid hormone (prohormone) made synthetically or naturally in the body
- Common forms
- Capsules, tablets, sublingual tablets, sprays (sold as 'prohormone' supplements)
- Boosting testosterone
- Building muscle and strength
- Enhancing athletic performance
- Anti-aging / general vitality
- Bodybuilding cutting or bulking cycles
Popular and traditional uses — not proof it works. See “Uses & effectiveness” below for the evidence.
It is a controlled anabolic steroid with hormonal risks and is best avoided unless prescribed and supervised.

Overview
Androstenediol is a steroid hormone that occurs naturally in the human body. It is a prohormone, which means the body can convert it into other hormones such as testosterone. It is not an herb or plant; the versions found in supplements are usually made in a lab.
Androstenediol has been sold as a 'prohormone' or 'testosterone booster' supplement, mostly to athletes and bodybuilders who hope it will raise testosterone, build muscle, or improve performance. Because of its hormonal activity and potential for abuse, the United States classifies it as a Schedule III controlled substance, similar to other anabolic steroids. It is also banned by sports organizations like the NCAA and the World Anti-Doping Agency (WADA).
How it works
Androstenediol sits one step away from testosterone in the body's hormone pathway. In theory, taking it gives the body more raw material to make testosterone and other androgens, which could affect muscle building, sex drive, and other testosterone-related functions.
It can also be converted into estrogen-type hormones in some people, which is why side effects can include breast tissue growth in men. Much of what we know is based on hormone chemistry and animal or small human studies rather than large, well-controlled trials, so the real-world effects in people are not well proven.
Does Androstenediol work?
How to read these evidence grades
Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.
Possibly Ineffective Athletic performance
Androstenediol taken orally, 100 mg twice per day, does not seem to add any significant increase in muscle strength or size when used for 12 weeks in conjunction with high-intensity resistance training.
Source & disclaimer. Effectiveness ratings and evidence summaries are provided by Natural Medicines (Therapeutic Research Center) and shown as licensed. Where Natural Medicines hasn’t rated a use, HelloPharmacist’s pharmacists may add their own reviewed rating and evidence (each such entry is labeled). This is educational information, not medical advice — talk with your pharmacist or doctor before starting, stopping, or changing a supplement.
Safety & precautions
Androstenediol is best thought of as a mild anabolic steroid, not a gentle supplement. Using it can disturb your body's natural hormone balance.
People who should avoid it include those with hormone-sensitive conditions (such as prostate, breast, or other hormone-related cancers), liver problems, heart disease, or high cholesterol. Teenagers and young adults whose bodies are still developing should not use it.
Pregnancy and breastfeeding: Do not use androstenediol if you are pregnant or breastfeeding. Androgen hormones can harm a developing baby, and the effects on a nursing infant are unknown.
Because it is a Schedule III controlled substance in the U.S., possessing or selling it without proper authorization may be illegal. Always check with a doctor or pharmacist first.
Side effects
Side effects are similar to those of other anabolic steroids and androgens. They may include acne, oily skin, hair loss or unwanted hair growth, mood changes or irritability, and changes in cholesterol levels.
In men, it can cause breast tissue enlargement (gynecomastia), shrinking of the testicles, and lowered natural testosterone production over time. In women, it can cause masculinizing effects such as a deeper voice, facial hair, and menstrual changes, some of which may be permanent.
More serious concerns linked to anabolic steroids include liver strain and increased cardiovascular risk. Stop use and seek medical care if you notice worrisome symptoms.

Dosing
There is no established safe or effective dose of androstenediol, and because it is a controlled substance, it is not a routine over-the-counter supplement. The body of research does not support a recommended amount.
If you are considering any product that contains it, do not rely on label claims. Speak with a doctor or pharmacist first, and never assume a higher dose is safer or more effective.
