Verdict: IMPI Red by LaCroy is a scented 15 mL pheromone spray with a warm, earthy musk fragrance. Its maker names four pheromone ingredients and says the bottle contains 4.5 mg in total, more detail than many competing listings provide. The amount of each compound and evidence that this finished cologne changes attraction have not been published on the product pages we reviewed. Buy it for the scent and format if those appeal to you, while treating its social-effect claims as unproven. See LaCroy’s specifications.

How we reviewed it
We checked the maker’s IMPI page, the Pheromones.com IMPI Red listing, its shipping terms and refund policy, and published research on human pheromones. This is a research-based assessment; we have not independently worn or lab-tested IMPI or verified individual testimonials.
Scent and wearing experience
LaCroy describes an earthy opening, a warm resinous and slightly spicy middle, and a musk-led base. The retailer similarly calls it a close-wearing masculine fragrance. These are seller descriptions, not our own scent test. A person who prefers bright or fragrance-free products may want a different option. Because it is scented, do not confuse it with LaCroy’s separate unscented products or the newer IMPI-X oil.
LaCroy recommends two to three sprays on skin or clothing. Pheromones.com gives a general six-to-eight-hour estimate for its scented pheromone products; real fragrance longevity can vary by amount applied, clothing, and skin. The old article’s claim that pheromone effects last only three to four hours had no reliable product-specific support and has been removed.
What is in the formula?
LaCroy identifies androstenone, androstenol, androstadienone, and androstanone and describes African essential oils in the fragrance. Its specification says 4.5 mg of selected pheromones per 15 mL bottle. That is a manufacturer claim about total content, not an independent lab result or a measure of clinical effectiveness. The maker does not break the total down by compound on its public product page. People sensitive to fragrance ingredients should check the package and ask the seller for the complete ingredient list before applying it.
Do its attraction claims hold up?
LaCroy says research involving androstenol and androstadienone supports its rationale. That does not establish that IMPI Red itself makes wearers more attractive or changes the behavior of people around them. A review of the search for human pheromones calls for more rigorous identification and testing of proposed compounds. We found no controlled test of the finished IMPI Red formula establishing the maker’s advertised social outcomes. The old page’s anonymous anecdotes about eye contact, flirtation, and respect were not sufficient evidence and have been removed.
Price, shipping, and returns
The retailer’s listing showed $60 for one 15 mL bottle when checked. That is $4 per mL before any tax. It lists free standard U.S. shipping, and its shipping page estimates three to five business days for USPS Ground Advantage. Faster and international shipping cost extra; international duties and customs charges are the buyer’s responsibility.
Pheromones.com’s refund policy, updated October 4, 2026, allows returns within 60 days of receipt, including opened bottles, for a refund of the product price. The buyer pays return postage, and shipping already paid is not refunded. Orders of $180 or more before discounts carry a 25% return processing fee. Its separate guarantee page also mentions a $10 fee for returned orders sent with free USPS shipping; because the pages differ in wording, confirm the fee with the retailer before ordering if it affects your decision. These are this retailer’s terms; another seller may have different policies.
Who is it for?
IMPI Red is most relevant to someone seeking a warm, close-wearing musk scent in a compact spray who values a disclosed total pheromone amount. It is less suitable for a buyer who wants individual ingredient concentrations, a light fresh cologne, or proven attraction effects. The small 15 mL bottle and $60 price also make scent preference and the return terms especially important.
Frequently asked questions
How much pheromone is in IMPI Red?
LaCroy says 4.5 mg of selected pheromones in the 15 mL bottle. It names four compounds but does not disclose the amount of each.
Is IMPI Red unscented?
No. The maker describes an earthy, spicy, resinous fragrance with a musk-led base.
Does it reliably increase attraction?
There is no controlled finished-product study cited on the pages we reviewed that establishes such an effect. Seller testimonials and research on isolated compounds do not prove the cologne’s outcome.
Can I return a used bottle?
Pheromones.com says opened bottles may be returned within 60 days of receipt. You pay return postage, and a fee may apply under its guarantee wording. Check the seller’s current terms before purchase.
Final verdict
IMPI Red has comparatively useful formula disclosure and a clearly described musk fragrance, but its 4.5 mg figure is seller reported and is no proof of attraction. At $60 for 15 mL, it makes the most sense for buyers who already like this style of scent and understand the retailer’s return costs. For our leading men’s pick, read our Nexus review.
