4-androsterone + Phenelzine Sulfate
Phenelzine Sulfate brand name: Nardil.
We found no known interaction between 4-androsterone and Phenelzine Sulfate in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.
4-androsterone and Phenelzine Sulfate
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Phenelzine Sulfate and 4-androsterone in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.
4-androsterone safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Why No Interaction Is Listed for Phenelzine Sulfate
Interactions in our licensed database are recorded against drug classes, not just single drug names. Phenelzine Sulfate is filed under 6 classifications — including monoamine oxidase inhibitors (maois), antidepressant drugs, serotonergic drugs. 4-androsterone has documented interactions with 1 drug class — the most serious being testosterone (moderate) — and none of Phenelzine Sulfate’s classifications are among them.
Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. 4-androsterone is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every 4-androsterone reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 27, 2026. The 4-androsterone and Phenelzine Sulfate records this page draws on were last updated July 10, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About 4-androsterone
What is 4-androsterone?
- Muscle building
- Strength and athletic performance
- Boosting testosterone
- Bodybuilding cycles
4-Androsterone (sometimes called 4-DHEA) is a lab-made prohormone marketed to bodybuilders as a way to raise testosterone and build muscle, but human studies are very limited and it carries real risks like liver strain, hormone imbalance, and cholesterol changes. Its legal status is uncertain in many places, and it may cause a positive result on drug tests. We do not recommend it without close medical supervision, and it should be avoided in pregnancy and breastfeeding.
Synthetic steroidal compound (not a plant part) · Capsules, tablets, transdermal gels or creams, liquid drops
An interaction check asks whether these two react with each other — it does not ask whether 4-androsterone is a good idea for someone in your situation. Here is what our 4-androsterone record says about it on its own.
4-androsterone: dosing
There is no established, medically recommended dose for 4-androsterone. Doses used in bodybuilding come from product labels and informal community advice, not from rigorous clinical research.Because purity and strength can vary between products and the risks are significant, we cannot recommend a specific amount. Never assume that a higher dose is safer or more effective.

About Phenelzine
What Is Phenelzine Used For?
Brand name: Nardil
Phenelzine treats depression in people described as “atypical,” “nonendogenous,” or “neurotic.” These patients often have a mix of anxiety and depression, along with phobic or hypochondriacal features (intense fears or excessive worry about health).
It is rarely the first antidepressant tried. It is more suitable for people who did not respond to the drugs more commonly used. Evidence is less conclusive for severe depression with endogenous features. These uses apply to Phenelzine Sulfate tablets and Nardil tablets.
Most-Reported Side Effects for Phenelzine Sulfate
From FAERS, the FDA’s public side-effect reporting system (0 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Phenelzine Sulfate Is Linked to Lower Levels of One Nutrient
Natural Medicines records Phenelzine Sulfate as a medicine that can lower these. This is not an interaction with 4-androsterone — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
