Athena Pheromone 10X is an unscented additive for men who want to keep wearing their own cologne or aftershave. It has a small published placebo-controlled study, which makes its research history more concrete than most pheromone products. The study is preliminary, however, and the product is expensive for something whose attraction effect remains uncertain. In our men’s pheromone buyer’s guide, Nexus remains our best overall shopping pick; Athena is a more specialized choice for buyers who specifically want a fragrance additive.
How we reviewed it: We checked Athena Institute’s current product page, mixing instructions, posted return policy, and the published men’s study. We have not worn 10X, independently analyzed the vial, or tested whether it changes how others respond.

Our verdict
Best for: Someone who already likes an alcohol-based cologne and wants to try an unscented additive while understanding that the research does not establish a predictable attraction effect for an individual buyer. Athena is less convenient if you want a spray you can use immediately, or if you expect a trial period for an opened vial.
- What we like: It does not require changing your preferred fragrance, and the men’s product has a published controlled study to examine.
- What to weigh: The study is small and relies on the men’s own activity logs; the formula is proprietary; mixing requires a separate screw-top bottle; the posted return policy applies to unopened items.
What the 10X study actually found
In a 1998 paper in Archives of Sexual Behavior, 38 heterosexual men ages 26 to 42 recorded a two-week baseline and then used either a pheromone additive or placebo for six weeks in a double-blind trial. More men in the active group reported increases over baseline in intercourse and sleeping beside a romantic partner. The paper’s authors described the findings as initial data needing replication.
That is relevant evidence for Athena 10X, but it is not a direct measure of women’s attraction: the outcomes came from men’s behavior logs, the group was small, and the research included Athena founder Dr. Winnifred Cutler. It does not tell us how likely a new buyer is to notice a change. The studies of Athena 10:13 concern the women’s product and should not be treated as additional proof for 10X. A later scientific review of proposed human sex pheromones also cautions against treating commonly marketed molecules as established human sex pheromones.
Formula, scent, and mixing
Athena describes 10X as a colorless, unscented additive. The full compound list and amounts are not public, so we cannot independently assess what is in the vial. The seller says it should not change the scent of your own cologne; we have not tested that claim on skin.
The manufacturer’s mixing guide says to pour the vial into a screw-top container of alcohol-based cologne or aftershave, then dab the blend on the skin at least every other day. Its product page specifies roughly 2–3 oz of fragrance and says to shake gently before each use. The original vial is not resealable after opening. Do not put the mixture in an atomizer or mix it into cream or oil; Athena sells a separate mixing bottle if your fragrance normally comes in a spray. The seller estimates a vial lasts four to six months when used as directed, which we have not independently checked.
Price and purchase terms
The manufacturer currently lists one vial for $99.50 and a six-pack for $500. Shipping options depend on the order. The site’s posted return policy says unopened, undamaged items can be returned within 30 days of receipt and that shipping charges are not refundable. Since 10X must be transferred out of its vial for use, do not assume you can try it and return an opened product. Confirm the current terms with Athena before ordering if returns matter to you.
Athena 10X vs. Nexus
Athena is designed to be added to a fragrance you already own. Nexus is a lightly scented spray that can be used on its own or layered under cologne. Athena’s small published trial is a meaningful distinction in its favor, while Nexus is simpler to use. Neither provides enough evidence to promise that it will make a specific wearer more attractive.
Frequently asked questions
Is Athena 10X the same as Athena 10:13?
No. 10X is the men’s product; 10:13 is marketed for women. Their studies and customer accounts should be evaluated separately.
Does Athena 10X have a scent?
The seller describes it as unscented and says it will not alter your cologne. We have not worn it to verify that.
Can I add it to a spray bottle?
Athena says no. Transfer it into a leakproof screw-top bottle with an alcohol-based fragrance and apply it by dabbing, following the current manufacturer instructions.
Does the study prove it works?
No. The 38-man study reported promising differences in self-recorded behaviors over a short period, and its authors said the initial findings needed replication. It cannot predict an individual buyer’s results.
Can I return it after trying it?
The posted order instructions describe returns for unopened, undamaged items within 30 days of receipt. Check with Athena before purchase for its current policy.
