Quick summary

  • What they are: pheromone colognes are fragrances with added steroid compounds, usually androstenone, androstenol or androstadienone, that are marketed as human sex pheromones.
  • Do they work? Independent reviews find no robust evidence that any of these compounds is a human pheromone. Positive studies tend to be small and have not held up when repeated.
  • What might help: wearing a scent you like can raise your own confidence, and one study found that this changed how women rated men on video. That effect came from an ordinary fragrance, not pheromones.
  • How to choose: look for named compounds with amounts, a full ingredient list, honest claims, a named maker with an address and a clear refund policy.
  • Safety: patch test first if you have sensitive skin, and check for androstenedione if you are a tested athlete or have a hormone condition.

We do not rank specific pheromone colognes in this guide. We have no reliable data showing that one works better than another, so we explain how to judge a label instead.

What are pheromones?

A pheromone is a chemical released by one member of a species that sends a signal to another member of the same species. A 2001 review in Chemical Senses proposed the working definition “chemical substances released by one member of a species as communication with another member, to their mutual benefit”. Pheromones are well established in many animals, which is why the 2015 review below argues it is possible that humans have them too.

Pheromone colognes rest on the idea that certain steroids linked to male odour, such as androstenone, which is derived from testosterone, send a signal to women when bottled and sprayed on.

That Chemical Senses review looked at whether humans have a working vomeronasal organ, an organ linked to pheromone detection in other mammals. It found conflicting evidence on that question. It also said chemical communication does appear to happen between people, but that several reported examples did not meet a proper definition of a pheromone.

Do pheromone colognes work? What the science says

The honest answer is that there is no reliable evidence they make you more attractive.

The main reviews

A 2015 review in Proceedings of the Royal Society B, by a University of Oxford zoologist, concluded there is “no robust bioassay-led evidence” that androstenone, androstenol, androstadienone or estratetraenol are human pheromones. It said positive results were “highly likely to be false positives”, citing small samples, overestimated effects, publication bias and lack of replication.

In a 2020 follow-up in Philosophical Transactions of the Royal Society B, the same author noted that almost 60 studies had reported significant results for androstadienone and estratetraenol, which “are quite possibly false positives”. He still thought humans may have pheromones, but said better methods, such as pre-registered studies, would be needed to find them.

A 2025 review in Physiology & Behavior looked at androstadienone again. It concluded that calling it a human sex pheromone “remains inconclusive”.

Positive and negative studies

Pheromone brands often cite a handful of positive results. Here is what those studies tested:

  • Speed dating (2008). In a study in Hormones and Behavior, women exposed to androstadienone rated men as more attractive at speed-dating events, in two out of three studies. The women were exposed to the compound; the men were not wearing it as a cologne.
  • Men’s diaries (1998). In Archives of Sexual Behavior, 38 men used a “synthesized human male pheromone” or a placebo for six weeks in a double-blind trial. More men on the pheromone increased intercourse and sleeping next to a partner, and the authors said the results needed replication. A 2004 reanalysis in Physiology & Behavior found no statistically significant increase in any behaviour in the pheromone groups, and “no support in data” that wearers became more attractive.
  • Faces (2017). A double-blind study in Royal Society Open Science exposed 94 people to androstadienone, estratetraenol or a control scent. The compounds had no effect on how attractive they rated opposite-sex faces.

People smell these steroids differently

A 2007 study in Nature found that androstenone smells “sweaty, urinous” to some people, “sweet, floral” to others and like nothing at all to others. Variation in a single smell receptor gene, OR7D4, explained part of this, and the same receptor responds to androstadienone. So a cologne loaded with androstenone might be pleasant, unpleasant or undetectable depending on who is standing next to you.

The confidence effect

There is one finding that may explain why some men feel these products work. In a 2009 study in the International Journal of Cosmetic Science, men were given either a scented, antimicrobial spray or an identical-looking spray without those ingredients. Men using the scented spray reported more self-confidence. Women rated them as more attractive on video clips, but not in still photos, which points to a change in the men’s behaviour. No pheromones were involved. Any fragrance you enjoy wearing could have this kind of effect.

What is in pheromone cologne?

Most products are a normal fragrance base (alcohol or oil plus scent) with one or more of these added:

Compound Where it comes from What the evidence shows
Androstenone An odorous steroid derived from testosterone No robust evidence it is a human pheromone; perceived very differently between people
Androstenol (alpha or beta) A related steroid Named in the 2015 review among compounds without robust evidence
Androstadienone The most studied “putative” male pheromone Mixed results, several null studies, status called inconclusive in 2025
Androsterone, epiandrosterone, androstanone Other steroids some brands add We found no human trials testing them as a worn fragrance for attraction
Androstenedione A testosterone precursor Not established as a pheromone; see safety below
Copulins Short-chain fatty acids from vaginal secretions Identified in humans in the 1970s, after work in monkeys; a 1976 rhesus study reported a lack of effect, and we found no good human trials

Two problems apply to nearly every product:

  1. Undisclosed amounts. Most brands name the compounds but not how much is in each spray. “Concentrated”, “amplified” or “10X” means nothing without a figure.
  2. Hidden ingredients. In the US, fragrance components can be listed simply as “Fragrance”, so you may not know what else is in the bottle.

Pheromone sprays vs oral pheromone supplements

Pheromone products come in two forms:

  • Sprays, oils and colognes put the compound directly on your skin, where it can evaporate and be smelled. This is the only route that matches how pheromones work in other mammals, although the human evidence is still weak.
  • Oral “pheromone boosters” are capsules marketed to raise your body’s own pheromone output. We found no clinical trial showing that a supplement changes body odour in a way that increases attraction.

In the US, a fragrance “marketed for promoting attractiveness is a cosmetic”, according to the FDA. Cosmetics do not need FDA approval before sale. If you are interested in supplements for testosterone or libido rather than scent, see our evidence guides to testosterone boosters and boosting sex drive and libido.

How to judge a pheromone cologne

Since no product has strong evidence behind it, judge the seller on transparency and fair terms. Here is what we check:

  1. Named compounds with amounts. The label or website should say which compounds are in it and how much, for example in micrograms or milligrams per millilitre. Names alone cannot be compared.
  2. A full ingredient list. Look for the base, the solvent and any known allergens. This matters if you have sensitive skin.
  3. Claims you can check. “Makes women want you” or “instant attraction” is a promise no study supports. Be more wary the stronger the claim.
  4. Citations that match the product. If a brand cites a study, look it up on PubMed. Check that it tested the same compound, in the same way, and that the quote matches the paper.
  5. A named company and address. You should know who makes it and where they are based.
  6. A clear refund policy. Check the time limit, whether opened bottles are accepted and whether shipping is refunded.
  7. Price per millilitre. Bottle sizes vary widely. Work out the cost per mL before comparing prices.
  8. Reviews with care. Testimonials on a seller’s own site are marketing. Reports of success are hard to judge because people who expect a product to work often feel more confident.

Are pheromone colognes safe?

Pheromone colognes are generally sold as ordinary fragrances, but a few points are worth knowing.

  • Skin reactions. The FDA lists fragrance as a major group of cosmetic allergens. Reactions can include hives, itchy skin, a rash, flaking skin and eye, nose and mouth irritation. Test a small amount on your inner arm first and stop if your skin reacts.
  • When to see a doctor. The NHS advises seeing a GP for persistent, recurrent or severe contact dermatitis. The FDA says to get medical help immediately for signs of anaphylaxis, such as wheezing or facial swelling.
  • Androstenedione. Some products list this testosterone precursor. In 2004 the FDA acted against androstenedione in dietary supplements, saying it “may increase the risk of serious health problems”, as reported in the Journal of the International Society of Sports Nutrition. That concerned pills. We found no data on how much is absorbed from a spray, but if you are a tested athlete or on hormone treatment, ask your doctor or anti-doping body first.
  • Application. Keep sprays away from eyes, mouth and broken skin.

Nexus Pheromones: a pheromone spray, not a pill

Nexus Pheromones, from Leading Edge Health, is sometimes described as a supplement. We checked the maker’s pages: it is a spray that you apply to your pulse points “like a cologne”, one to three sprays on the neck and chest. It lists seven compounds (androstenone, alpha-androstenol, androsterone, epiandrosterone, beta-androstenol, androstenedione and androstanone) but gives no amounts. On 27 September 2026 one bottle was listed at $49.00, and the maker offers a 67-day money-back guarantee, minus shipping and handling.

Its strengths are a named maker, a named compound list and a return window. Its weaknesses are the same as the category: no amounts, no study of the product itself, and a “Scientific Proof” quote that comes from a study of androstadienone, which is not in the formula. Read our full Nexus Pheromones review for the details, or see the official Nexus Pheromones site for current prices and terms.

Our verdict

Pheromone colognes are fragrances with a scientific-sounding story. The research does not show that androstenone, androstenol, androstadienone or copulins make people more attracted to you. If you want to try one, choose a scent you actually like, buy from a seller that discloses its ingredients and offers a fair refund, and patch test it first. Expect any benefit to come from how you feel wearing it, not from a chemical signal.

FAQ

Do pheromone colognes actually work?

There is no reliable evidence that they do. Independent reviews find no robust proof that androstenone, androstenol, androstadienone or estratetraenol are human pheromones, and several controlled studies found no effect on attractiveness ratings.

What is the best pheromone cologne for men?

We do not name one, because we found no reliable data showing that any product works better than another. Choose a product that discloses its compounds and amounts, lists all ingredients, avoids attraction promises and has a clear refund policy.

What pheromone attracts women?

None has been proven to. Androstenone and androstadienone are the most marketed, but the research is weak and mixed, and people perceive androstenone very differently, from pleasant to unpleasant to odourless.

Are pheromone colognes safe?

For most people they are like any fragrance, but skin reactions are possible. Patch test first. Some products contain androstenedione, a testosterone precursor, so tested athletes and people on hormone treatment should ask a doctor first.

Are pheromone pills better than sprays?

We found no clinical trial showing that an oral pheromone supplement increases attraction. Sprays at least put the compound where it can be smelled, although the evidence for sprays is also weak.

Can you wear pheromone cologne with regular cologne?

Some makers say you can, including the maker of Nexus Pheromones. We found no research on whether layering changes any effect, so this is a matter of which scent you prefer.

Is Nexus Pheromones a cologne or a supplement?

It is a spray worn like cologne, not a supplement. The maker lists seven steroid compounds without amounts and offers a 67-day money-back guarantee.
