Androsterone

Evidence: Anecdotal

A weak-androgen metabolite present in human sweat and urine that the community rates highly as a "respect and status" pheromone.

Androsterone is one of the oldest names in this whole story — a weak androgen metabolite first isolated from human urine in 1931, in the work that helped open up steroid chemistry. The pheromone community rates it near the top as a “respect” molecule, tied to perceived leadership and status. It has a firmer identity and more history than most list entries, which makes it a clean test of the balanced view: a real compound, consistent reports, and thin direct evidence.

What it is, structurally

Androsterone is 3α-hydroxy-5α-androstan-17-one, a saturated androstane and a downstream metabolite of testosterone and DHT. It occurs naturally in sweat, urine and blood, and it has weak androgenic activity in its own right. Because it sits at the end of an androgen pathway rather than the start, it is a genuine component of the body's steroid output, not a synthetic add-on.

CAS number and chemistry

The CAS Registry Number for androsterone is 53-41-8. Molecular formula C19H30O2, molar mass 290.4 g/mol, PubChem CID 5879, systematic name 3α-hydroxy-5α-androstan-17-one. It is a well-characterised molecule with a long registry history — no ambiguity to flag here, which is a pleasant change from some of its neighbours on this list.

What wearers report

Androsterone is one of the more consistently described “status” molecules in community field reports: users say they come across as more authoritative, respected and taken seriously, with a steadier, leadership-leaning presence rather than an overt attraction hit. These are self-reports, and expectancy is always part of a deliberately worn scent. But the profile is specific and repeated across independent users, which earns it an honest hearing.

The mechanism worth crediting

Androsterone has a more direct claim than the pure precursors, because it is genuinely present in human body odour. As a saturated androstane it also sits in the same axillary steroid pool as the 16-androstenes and can parallel or feed that signature. The plausible reading is that added androsterone reinforces a steroid profile other people already read subconsciously — close in spirit to how androstenone is thought to work. What is missing is a controlled human trial of worn androsterone as a status signal, so the mechanism is credible and undemonstrated.

Does any pheromone product use it?

Androsterone is a staple of dominance- and status-leaning blends, often paired with androstenone and epiandrosterone . If a product markets a “respect” or “authority” profile, androsterone is frequently the molecule behind that framing. Our best pheromone perfumes for men roundup notes which picks lean this direction.

The honest read

Androsterone is a real, long-known body-odour steroid with consistent community reports of a respect-and-status effect and a plausible mechanism through the axillary steroid signature. It is one of the better-founded “hormone-adjacent” entries on this list — which still means field reports plus reasonable chemistry, not a controlled trial. Wear it as a credible status note with honest expectations.

How to use it, and what to expect

Androsterone is a subtle, status-leaning note, and it tends to show best in the settings where being read as steady and credible actually helps — work, negotiation, formal social situations — rather than as a loud attraction play. It is commonly paired with androstenone for a harder dominance edge, or with epiandrosterone to add likability to the authority.

As with the whole family, apply it lightly on warm skin and let the social feedback guide you rather than piling it on. The reported effect is a shift in how you are perceived before you speak, not a switch that flips a room — so the realistic goal is a small, steady edge, used consistently, not a dramatic overnight change.

FAQ

Is androsterone a pheromone?

It is a genuine component of human body odour and a strong pheromone candidate by that measure, widely reported as a status molecule. Direct controlled evidence for the worn effect is still lacking.

What does androsterone smell like?

Faintly musky and much subtler than androstenone; most of its reputation is about the social read rather than a strong odour.

How is androsterone different from epiandrosterone?

Epiandrosterone is the 3β epimer — the same skeleton with the hydroxyl flipped — and is described more as a likability/charm molecule than a status one.

How should you wear androsterone?

Lightly, on warm pulse points, usually as part of a blend rather than raw. It suits professional and formal-social settings where a steadier, more credible read is an advantage.

Is androsterone a steroid or a pheromone?

Both. It is a genuine steroid metabolite of testosterone and DHT that is present in human body odour, which is exactly why it is also a strong pheromone candidate. The two descriptions are not in conflict — the pheromone case rests on it being a real body steroid.
