Our testing notes.
This is a 3-pack of PherX's "attract men" oil at $199.90, marketed as "20mg human pheromones, extra strength."
The real core, androstenone, androstenol, androstadienone and copulins, is reasonable, but the headline misleads. Pheromones are active at microgram doses, so "20mg / extra strength" sounds impressive without being a meaningful quality signal, and the listed oxytocin is filler on skin. Buying three bottles at this price compounds the risk, given PherX's poor independent reputation.
Judge it on the genuine compounds and ignore the dosing marketing. Unless you're a committed user, a single bottle of a disclosed, validated brand is a far better starting point than a $199 3-pack.
