The Non-Financial Ledger

There is a specific kind of embarrassment that comes with buying something that was supposed to make you more lovable. Pheromone products are not sold to people who are simply curious about fragrance chemistry. They are sold to people who are lonely, or nervous, or freshly single, or quietly afraid that something about them is not enough on its own. The marketing knows this. It speaks directly to the part of a person that wonders if there is a shortcut to connection, a scientific edge that can be spritzed on before a first date or worn to a party where you don’t know anyone.

India Winslow bought the Pure Instinct True Blue Pheromone Body Spray on Amazon in March 2022. She read the label. She believed it. That is not a failure of intelligence; it is the predictable result of being told, in confident, clinical-sounding language, that a product contains “human-compatible pheromones” capable of “influencing moods, emotions and affections.” The company told her it was science, not myth. She trusted that.

What she actually received was a scented liquid. Whatever fragrance compounds were in the bottle, they could not do what the label said. They could not be detected by the people around her in any pheromone-mediated sense, because the human body does not have the equipment to receive that signal. The organ that would need to process pheromone information, the vomeronasal organ, is vestigial in adult humans. It has no working neural connections. It has been studied, repeatedly, and consistently found to be non-functional for exactly the purpose Pure Instinct claimed it served.

There is something uniquely dishonest about selling someone a product that exploits their desire for human connection while knowing, or having every reason to know, that the product’s core promise is scientifically impossible. This is not a case of a supplement with uncertain benefits or a cosmetic with overstated results. The mechanism Pure Instinct described on their website is one that does not exist in the human body. The organ they named as the pathway for their products to work is one the scientific community has documented as nonfunctional.

People bought these products to feel more desired, more magnetic, more capable of drawing someone toward them. They applied a body spray or dabbed on a perfume oil, went out into the world, and felt — what? Confidence, perhaps, from the placebo of believing the product was working. Or disappointment, when nothing changed. Or nothing at all, because the product was just a fragrance and did exactly what any fragrance does: it smelled nice. The price premium they paid for the pheromone claim bought them nothing. The science said so before they ever clicked “Add to Cart.”

The lawsuit describes the potential damages in terms of a “price premium attributable to the false and misleading pheromone statements.” That language is precise and legal and correct. But it does not capture what it feels like to realize you were sold a fantasy about your own desirability by a company that knew — or should have known — it was impossible to deliver.

There are tens or hundreds of thousands of people who bought these products. Some of them spent real money they couldn’t easily spare. Some of them were teenagers. Some of them were people navigating grief or social anxiety or the slow work of rebuilding a life. Every single one of them was told it was science, not myth. Every single one of them deserves their money back.

Legal Receipts: What The Filings Actually Say

The complaint filed February 19, 2025 contains direct quotes from Pure Instinct’s own marketing. These are not interpretations. These are the words the company put on its website and product labels, side by side with what the science says.

“Human-compatible pheromones . . . capable of influencing moods, emotions and affections and triggering social responses.”

— Pure Instinct website, as cited in Complaint ¶14

“It’s not myth, it’s science.”

— Pure Instinct website, as cited in Complaint ¶14

“Enhance your natural magnetism and attraction” and “amplify your . . . desirability.”

— Pure Instinct product descriptions, as cited in Complaint ¶15

“Alluring fragrance[] with human-compatible pheromones” and “the first pheromone fragrance.”

— Pure Instinct Amazon product listing for “The Original Pheromone Infused Essential Oil Perfume Cologne,” as cited in Complaint ¶16

“The human VNO has no function in perception and processing of the most likely human pheromone and a control odor . . . these results provide strong evidence that the human VNO has no obvious function.”

— Frasnelli et al., Human Brain Mapping (2011), cited in Complaint ¶20

“Androstadienone has ‘never been shown to be a human pheromone.'”

— Wyatt, Royal Society Proceedings B (2015), cited in Complaint ¶23

Societal Impact Mapping

Public Health: The Regulatory Violation Hidden in the Bottle

This case carries a public health dimension that goes beyond a simple consumer fraud dispute. The FDA’s classification of aphrodisiac-claim products as unapproved drugs has serious implications for the safety framework around over-the-counter personal care products.

• Under 21 C.F.R. §310.528, any product that claims to “arouse or increase sexual desire” is classified as an aphrodisiac drug product. Such products are “misbranded” under federal law unless they receive formal FDA approval, which requires safety and efficacy data. Pure Instinct’s products carry no such approval.
• The FDA has stated on record that there is “a lack of adequate data to establish general recognition of the safety and effectiveness of any of these ingredients, or any other ingredient, for OTC use as an aphrodisiac.” The complaint directly quotes this regulatory language, establishing that the agency has already reached a categorical conclusion.
• By allowing unapproved drug-claim products to remain on the market without regulatory challenge, the system creates a loophole: companies can make drug-equivalent claims about their products while sidestepping the clinical trial and approval infrastructure that protects consumers from ineffective or unsafe interventions.
• The complaint argues that any violation of 21 C.F.R. §310.528 also constitutes unlawful conduct under California Health & Safety Code §109875 et seq., the Sherman Food Drug and Cosmetic Law. California’s parallel framework means these violations carry state-level consequences in addition to federal ones.
• Consumers who use products believing they have FDA-recognized functional properties may also forgo other legitimate approaches to the concerns the products claim to address. The exploitation of trust in scientific language specifically undermines public understanding of what regulatory approval actually means.

Economic Inequality: Who Pays the Pheromone Premium

The financial harm in this case is structured in a way that concentrates its damage on people with the least capacity to absorb it. The pheromone premium is a tax on loneliness, and it falls hardest on those who can least afford it.

• The complaint identifies the primary injury as the “price premium attributable to the false and misleading pheromone statements.” That premium exists entirely because of the scientific claims. Remove those claims, and the products are ordinary fragrances sold at fragrance prices.
• Pure Instinct products are sold primarily through Amazon, a retail platform where price comparisons are easy and where marketing copy carries significant weight in purchase decisions. Consumers on Amazon who see the word “pheromone” and read clinical-sounding descriptions have no easy mechanism to access the peer-reviewed literature that dismantles those claims.
• The complaint estimates tens or hundreds of thousands of class members. The amount in controversy exceeds $5,000,000. Each individual transaction may have been relatively modest, but the aggregate transfer of money from consumers to two California corporations, based on a false scientific premise, represents a significant upward wealth transfer.
• The lawsuit’s structure as a class action is itself a recognition of economic reality: individual class members likely could not afford to bring solo lawsuits to recover the cost of a body spray or perfume oil. The class mechanism is the only path to accountability at the scale of the harm.
• The complaint also notes that if consumers had known the truth, “the price of Defendants’ Products would crater.” This framing is significant: it acknowledges that the entire price structure of the product line was built on deception. Every consumer who paid that price paid a premium for a lie, and that lie was equally accessible to consumers at every income level who shopped on Amazon.
• Plaintiff India Winslow is domiciled in Patterson, California, a Central Valley city where median household incomes are significantly below the state average. The products she purchased were sold online, available nationally, positioned specifically to appeal to people seeking a scientific solution to personal and social challenges. That is a marketing strategy that reaches people in every economic bracket, and extracts money from all of them equally for something that cannot work.

The “Cost of a Lie” Metric

The complaint places the amount in controversy at over $5,000,000. Here is what that number means in human terms.

What Now: Watchlist, Accountability, and Action

Two California corporations built a brand around a scientific claim that multiple peer-reviewed studies had already dismantled. They received formal legal notice in October 2024 and did nothing. Here is who has the power to act, and what you can do.

The Defendants

• W.T.F.N. Inc. (dba Classic Erotica / Pure Instincts) — 20950 Lassen Street, Chatsworth, California. The manufacturer and primary marketer of the Pure Instinct product line. Received CLRA demand letter October 22, 2024. Did not agree to correct violations.
• Oui Lab, Inc. — 15362 Valley Blvd., City of Industry, California. Owns and operates IntiMD.com. Identified in the complaint as holding itself out as the owner of the product line and managing the support email for the products sold under W.T.F.N.’s brand. Received demand letters both constructively (October 25, 2024) and directly (February 14, 2025).

Legal Team on This Case

• Benjamin Heikali, Katherine Phillips, and Ammad Bajwa of Treehouse Law, LLP, Santa Monica, CA — lead counsel for plaintiff.
• Zachary Arbitman and George Donnelly of Feldman Shepherd Wohlgelernter Tanner Weinstock & Dodig, LLP, Philadelphia, PA — co-counsel (Pro Hac Vice application forthcoming).

Regulatory Watchlist

• FDA (Food and Drug Administration): The primary federal body with authority over mislabeled and misbranded drug products. 21 C.F.R. §310.528 is directly cited in this complaint. File a consumer complaint at fda.gov/safety/report-a-problem.
• FTC (Federal Trade Commission): Jurisdiction over deceptive advertising and unfair business practices. Pure Instinct’s “It’s not myth, it’s science” claim on its website falls squarely within the FTC’s deceptive advertising enforcement scope. Report at reportfraud.ftc.gov.
• California Department of Consumer Affairs: State-level enforcement under the California Consumer Legal Remedies Act (Cal. Civ. Code §1750 et seq.) and California’s Unfair Competition Law (Cal. Bus. & Prof. Code §17200). Both statutes are invoked in this complaint.
• California Health Department / Sherman Law Enforcement: The California Health & Safety Code §109875 et seq. (Sherman Food Drug and Cosmetic Law) parallels federal FDA requirements, including prohibitions on false and misleading labeling. California’s enforcement arm has independent authority to act.
• CFPB (Consumer Financial Protection Bureau): While primarily a financial regulator, the CFPB tracks and reports on deceptive product marketing that results in consumer financial harm. Documenting cases helps build the public record.

What You Can Do Right Now

• If you purchased any of the 15 Pure Instinct products listed in Exhibit A of the complaint, you may be a member of the proposed class. Visit ClassAction.org (which hosts this complaint in its searchable database) to track case developments and determine if you are eligible to participate.
• Leave documented, factual reviews on Amazon and any other retailer where these products are sold. Cite the lawsuit case number (2:25-cv-01393) and the scientific sources referenced in the complaint. Accurate information in public retail spaces disrupts the marketing pipeline.
• Share the complaint document directly. It is publicly filed in the Central District of California and is in the public record. Send it to anyone you know who has purchased or is considering purchasing pheromone products from any brand. The underlying science applies across the category, not just Pure Instinct.
• Support consumer protection advocacy organizations that monitor deceptive marketing in wellness and personal care categories. Organizations like the National Consumer Law Center and Consumer Reports actively track cases like this and advocate for stronger regulatory enforcement.
• Talk to your community. The people most likely to buy pheromone products are often the people with the least access to scientific literacy resources and the least free time to research purchase decisions. Word of mouth through trusted networks remains one of the most effective tools against predatory marketing.
