The LaCroy Approach

At LaCroy, we focus on the research, synthesis and formulation of highly purified pheromone compounds. Our pheromones are produced to pharmaceutical-grade purity, verified through analytical testing to ensure concentration and consistency. Every formula is put through rigorous lab analysis. Our lab ensures only the purest, most potent pheromones reach you—with visible analytical data to prove it.

These compounds are then carefully incorporated into refined fragrance compositions designed to complement natural chemistry rather than overwhelm it.
