Our verdict: Pherone Formula M-15 (“Power”) is a 10 mL dab-on pheromone formula marketed to men. Pherone lists 3 mg of androstenone in the bottle and a $49.95 price, but does not name or quantify the other components of its blend. That is more specific disclosure than many pheromone products offer, yet it does not establish that wearing M-15 reliably changes anyone’s attraction or mood. Consider the product only with realistic expectations, follow its small-dose directions, and review the 30-day return terms.
How we reviewed Formula M-15
We checked the current Pherone M-15 product listing, the company’s guarantee and ordering and shipping information on October 4, 2026. We compared its stated formula and application with the claims in the former review. We have not bought or worn M-15, independently assayed its contents, or measured attraction or social outcomes.

What is in M-15?
Pherone’s listing calls M-15 a blend and states it contains 3 mg of androstenone in a 10 mL bottle. That is the maker’s stated amount, not an independent laboratory result. The page does not identify the “synergistic” compounds, their doses, or the full carrier formula. The old review named androsterone and androstenol and claimed an optimal ratio, but we could not verify either molecule in this specific formula from the current disclosure.
Pherone compares M-15 with M-11, saying M-15 emphasizes androstenone more strongly. Its M-11 page states 1 mg of androstenone, providing a concrete difference in the maker’s claims. The comparison does not prove which formula produces a better social outcome.
Does it improve attraction or confidence?
Pherone markets M-15 as a way to gain attention and make women feel relaxed and happy. Those are intended effects stated by the seller. Ingredient identity and dose alone do not establish the behavior of a finished mixture in everyday settings. A research review of proposed human sex pheromones explains the need for careful chemical identification and controlled behavioral work. We did not find a published controlled trial of this exact M-15 product establishing the advertised effects.
The company displays favorable customer testimonials. They describe individual experiences, not blinded comparisons. We also could not verify the prior article’s claim about “thousands of users” or its declaration that M-15 is among the most consistently effective products. Those assertions have been removed.
Scent and how to apply it
Pherone’s general FAQ calls its formulas unscented and says they can be worn with a cologne. We have not smelled M-15 and cannot confirm the old article’s “clean, musky” description or a six-to-ten-hour effect. The current M-15 page instructs buyers to begin with one dab and use no more than two drops at a time. That contradicts the old review’s one-to-two-spray directions. Follow the current bottle label and avoid overapplication.
The seller says a 10 mL bottle can last for months of daily use. Actual duration depends on drop size and frequency; it is not a measured wear-time claim. If you are sensitive to a carrier or fragrance, ask for the complete ingredient list before use.
Price, shipping and returns
At our check, M-15 was listed at $49.95 for 10 mL. The product page advertises free shipping on orders of $75 or more, while Pherone’s ordering page also lists older-looking per-order shipping prices and free shipping with two items. Because these terms are presented differently, confirm the actual charge at checkout. Delivery times and promotions can change.
The guarantee page says dissatisfied buyers may return an order within 30 days after receiving it for the purchase price. It instructs customers to email returns@pherone.com with the order number to obtain a Return Authorization before sending it back. Shipping and handling are excluded or may be deducted, including a standard shipping charge if the original order shipped free. A return without authorization may incur a restocking fee.
How does M-15 compare with Nexus?
M-15 is a concentrated, dab-on formula whose seller discloses a stated androstenone amount. Nexus is a men’s pheromone fragrance with a different scent experience and seller policy, covered in our separate review. Compare the use you want, available ingredient information, total cost and returns. We have not measured attraction outcomes for either finished product.
Frequently asked questions
Is Pherone M-15 a spray?
No. The product page gives dab/drop directions for a 10 mL bottle. The old review’s spray instructions were incorrect.
How much androstenone is in M-15?
Pherone states 3 mg per 10 mL bottle. That is a seller declaration; we have not assayed the product independently.
Does M-15 contain androstenol or androsterone?
The current M-15 page does not name those compounds. It describes additional synergistic pheromones without identifying them, so we cannot verify the prior review’s ingredient list.
What is the return window?
Pherone says returns are accepted within 30 days after receipt. Obtain a Return Authorization first, and expect shipping and handling exclusions or deductions.
Final verdict
M-15 provides a stated androstenone amount, a small dab-on format and a published 30-day guarantee at a $49.95 list price. It leaves the rest of the blend undisclosed, and we found no controlled finished-product evidence for the promised attraction or mood effects. Judge it on those concrete product and purchase details rather than the old article’s unsupported performance claims.
Editorial note: Product, shipping and guarantee details checked October 4, 2026. This is a research-based review; we have not independently tested M-15 or measured attraction outcomes.
