LaCroy IMPI Original, commonly sold as IMPI Red, is a 15 mL scented pheromone cologne for men. Unlike neutral fragrance additives, it combines a deliberately earthy, musk-led scent with four named steroid-derived odorant compounds. LaCroy markets the mixture around strength, masculinity and seduction. Those are positioning claims: no independent clinical trial of the finished IMPI formula establishes that spraying it on causes another person to feel attraction, desire or respect.
Research method: We compared the LaCroy manufacturer’s IMPI page, the US IMPI Red retail listing and Aroma Fero’s UK stock and pricing information. Information about components, pricing, bottle format and scent comes from these sources; effectiveness claims are evaluated separately. This is not a hands-on fragrance or laboratory test.

Our verdict: pros and cons
Pros
- Four identified ingredients: unusual clarity compared with proprietary blends that name none.
- Manufacturer-declared total: 4.5 mg across the 15 mL bottle makes approximate total loading understandable.
- Complete fragrance proposition: earthy, resinous and musky notes rather than an unscented additive.
- Clear use instructions: LaCroy suggests two or three sprays.
- US seller refund offer: Pheromones.com advertises a 60-day refund of product cost, subject to terms.
Cons
- Independent evidence for the finished cologne’s attraction and dominance claims is lacking.
- Individual compound doses and third-party batch assays are not provided.
- Manufacturer and UK listings show stock limitations.
- The earthy/musky profile may be polarizing compared with a fresh daily cologne.
- The $60 price is relatively high for only 15 mL when effects are unproven.
Formula: four ingredients, but how transparent is it?
LaCroy identifies androstenone, androstenol, androstadienone and androstanone and states a total of 4.5 mg selected pheromones in each 15 mL bottle. That averages to 0.3 mg/mL of total claimed pheromone material, assuming the listed amount applies to the entire finished product. It does not establish how much of each substance is present, nor the deposited dose from a specific spray pump. Those require individual concentration figures, atomizer output data and, ideally, third-party batch verification.
Androstenone and androstenol
These steroid-derived compounds have been investigated as constituents of human body odors and are frequently used in commercial pheromone marketing. Individual sensitivity to their odor varies. Their presence in a fragrance does not demonstrate that a wearer becomes more dominant, attractive or sexually appealing to others in daily life. Context, expectation, fragrance liking and ordinary interaction are major uncontrolled variables in buyer accounts.
Androstadienone
Some research has examined androstadienone in laboratory settings with questions concerning mood or perception. Such studies do not establish that a commercial blend reliably changes dating outcomes. LaCroy’s statement that its own studies show increased masculine and sexual perception should be understood as a manufacturer claim unless methods, raw data and independently replicated results are available for inspection.
Androstanone and mixed-formula uncertainty
Androstanone is another named member of the mixture, but the company does not disclose how the four compounds are proportioned. Formulation ratios may affect odor character and skin feel, yet the absence of a public formula breakdown means we cannot infer a unique behavioral effect or quantitatively compare IMPI with another brand. The African essential oil component further shapes the scent, independently of pheromone claims.
What does IMPI Original smell like?
LaCroy describes an earthy opening inspired by African essential oils, a warm resinous and slightly spicy middle, and a smooth, musk-led base. A US reseller likewise characterizes the fragrance as dry, earthy and subtle rather than a highly projecting nightlife spray. That places it closer to a skin-conscious masculine scent than a bright, citrus-heavy everyday perfume, at least according to the sellers’ descriptions.
We have not worn or smelled IMPI ourselves. Scent impression, strength and longevity should therefore not be treated as independently confirmed. The US retailer says its pheromone fragrances typically last six to eight hours, but this broad retail statement is not a controlled IMPI-specific longevity measurement and does not establish duration of any behavioral effect.
Application and comfort
The company instructs customers to use two to three sprays on skin or clothes. Start with the actual label’s directions rather than automatically increasing dose. Because IMPI is an alcohol-based scented spray, avoid spraying toward eyes, inhaling mist or applying to damaged or irritated skin. Allow it to dry and keep it away from ignition sources. Anyone sensitive to fragrance or essential oils should proceed cautiously.
Even an enjoyable cologne cannot manufacture consent or genuine chemistry. Its best-supported role is as a fragrance that the wearer and people nearby may or may not enjoy.
IMPI Original vs. IMPI-X and other pheromone colognes
IMPI Original versus IMPI-X: The original is a 15 mL aluminium spray with an earthy musk-led profile and a claimed 4.5 mg load. The manufacturer’s IMPI-X is a 10 mL oil-based roll-on, advertised as fresher, sportier and more practical for daytime wear. It is a separate product and should not be confused with the original IMPI formula and presentation.
IMPI versus LaCroy NPA Touch for Men: NPA Touch is an unscented 12 mL fine-mist spray with 2.5 mg claimed pheromone content, designed to layer with a preferred cologne. IMPI is scented and lists four named ingredients, with a higher stated total load. Differences in total bottle content are not evidence of superior efficacy.
IMPI versus Apex Imprint: The latter is marketed toward bonding and scent memory, while IMPI emphasizes assertive masculine presence. These are advertising angles, not independently verified effects on other people’s thoughts or decisions.
IMPI versus Nexus Pheromones: Both occupy the male-pheromone fragrance category, but buyers should compare scent, cost, bottle format and guarantee conditions instead of accepting specific attraction promises.
Price, availability and return policy
The manufacturer and US retailer each show $60 for IMPI Original/Red, equivalent to $4 per mL before taxes and other charges. The manufacturer currently marks its listing unavailable, whereas the US seller shows an active shopping route. A product displayed for sale is not a guarantee of immediate inventory, so verify availability at checkout.
Aroma Fero advertises a reduced £42.90 price from £55 for the 15 mL spray, but explicitly labels it out of stock. Currency, delivery costs, duties and return policies differ between markets. The US retailer advertises free USPS delivery within the US and Puerto Rico and a 60-day product-cost refund; review detailed terms before purchasing.
Who should buy IMPI—and who should skip it?
Consider IMPI if you enjoy earthy or resinous scents, like musk-forward colognes and want a 15 mL travel-sized specialty fragrance from an established supplier. Its known four-compound list may appeal to readers comparing label transparency.
Skip it if you prefer clean citrus, need a bargain everyday spray, require fully disclosed concentrations and clinical product testing, or expect the scent to guarantee sexual interest or respect. The dominant consideration should be fragrance preference and real purchase value, not the manufacturer’s projected social effects.

How many sprays should I use?

Does IMPI scientifically increase attraction?
There is no reliable independent clinical trial of the finished IMPI spray establishing predictable romantic or dominance effects.
Final verdict
LaCroy IMPI Original is worth evaluating as a distinctive earthy, musk-led specialty cologne, but its behavioral claims remain unproven. It offers a compact 15 mL spray, four named compounds, a claimed 4.5 mg total loading and a $60 US price. Those concrete details are more persuasive than claims about dominance and instant attraction. Current manufacturer and UK stock restrictions, the absence of individual dosage data, and a lack of independent finished-product efficacy studies limit our recommendation. If you choose it, buy for its scent and format—not for a promised response from other people.
