Short answer: Androstenone is an odorous steroid that occurs in human body odor and is a well-established chemical signal in pigs. People can perceive it very differently, partly because of variation in an odor receptor gene. That does not establish that an androstenone spray makes a person more attractive, dominant, or confident. The evidence for those product claims in humans remains insufficient.
Established: People differ in whether and how they smell androstenone; the OR7D4 receptor contributes to that variation.
Studied: Experiments have examined perception, mood, and social judgments under specific conditions.
Unproven: An androstenone cologne reliably causes attraction or alters real-world dating outcomes.
Buying implication: Judge a scented product by its fragrance, disclosure, price, and return terms, not a promised social result.
What is androstenone?
Androstenone, also called 5α-androst-16-en-3-one, is one of the 16-androstene steroids studied in animal and human chemical communication. It has a documented pheromone role in pigs and has also been detected in human body odors. A chemical’s function in one species cannot be assumed to carry over to another. Calling androstenone a proven human sex pheromone goes beyond the available evidence. See the research review by Tristram Wyatt.
What does androstenone smell like?
There is no universal answer. In a human odor-perception study, people described the compound as unpleasant and sweaty or urinous, pleasant and sweet or floral, or effectively odorless. Variation in the OR7D4 odorant receptor helped explain differences in sensitivity and pleasantness ratings. That is evidence about smell perception, not evidence that the chemical attracts other people.
In a finished cologne, the fragrance oils and the compound’s concentration also affect what a wearer notices. A product calling itself “androstenone” may be scented or unscented and may contain other compounds. Read the actual ingredient and concentration disclosures rather than assuming two products with the same marketing term will smell or wear alike.
Does androstenone increase attraction?
Research on human chemical communication is ongoing, but no robust evidence establishes androstenone as a human pheromone with a predictable attraction response. Wyatt’s review argues that widely marketed steroid candidates require rigorous testing from first principles. An older controlled experiment exposed 200 students to androstenone or comparison odors while they rated a photograph and their mood. It found some condition-dependent judgments, but it did not show that wearing androstenone increases dating success or attraction. Findings in a laboratory task should not be translated into a guarantee for a retail spray.
There is also no established “alpha” dose that reliably creates dominance or instant attention. A pleasing fragrance may influence a wearer’s confidence or another person’s impression in ordinary ways; that possibility does not prove a specific pheromone mechanism. Testimonials cannot isolate the role of one ingredient from the scent, expectations, behavior, and setting.
How to read an androstenone product label
| Check | Why it matters |
|---|---|
| Compound name | Confirm the seller actually identifies androstenone; “pheromone blend” alone gives no composition. |
| Amount and bottle size | Milligrams per bottle and volume help compare what is disclosed, but a higher amount is not proof of better outcomes. |
| Carrier and fragrance | Alcohol, oil, and added fragrance affect application and scent preference; review the ingredient label if sensitive. |
| Testing | Ask whether claims come from controlled tests of the finished product, not general studies of isolated molecules. |
| Price and returns | Check current terms, especially whether an opened fragrance can be returned and who pays postage. |
For an example of a multi-compound product whose maker names androstenone and gives a total blend amount, see our IMPI Red review. The disclosed total does not reveal the amount of androstenone alone or demonstrate an attraction effect.

Common questions
Is androstenone a human pheromone?
It is a recognized pig pheromone and an odorous compound detected in humans. A reliable human pheromone function, especially an attraction response, has not been established.
Why do people disagree about its smell?
Human sensitivity and perceived pleasantness differ. Research links part of that variation to the OR7D4 odorant receptor.
Will a stronger concentration work better?
No reliable dose-response rule establishes a better attraction outcome in commercial colognes. More of a strong-smelling ingredient may simply change the fragrance experience.
Can I judge a blend by the androstenone listed on the label?
Only partly. Other ingredients, concentration, fragrance, and carrier matter. The presence of one compound does not establish the finished product’s effects.
Final verdict
Androstenone is an interesting odorant with measurable differences in human perception. It remains a poor basis for promises of instant attraction or “alpha” behavior. If you are shopping for a pheromone cologne, choose a scent you like and check the maker’s disclosures and return policy. Read our Nexus review for a product-level assessment.
