Pure Copulins 2mg/10ml Pheromone Concentrate.

Pure Copulins is a building block, not a finished perfume. LAL sells it as an unscented concentrate of copulins, the aliphatic acids women produce naturally that the community ties to higher male testosterone response and lowered inhibition.

Copulins are among the most primal and most argued-over compounds in the category. Reports run from strong male attention to nothing at all, and the raw material carries a musky edge some people find off-putting, which is why it usually goes under a cover fragrance instead of worn alone. Subjective, as always.

This is an experimenter's product. One molecule, a trickle of reviews, best suited to women who already mix their own and want to add copulins on purpose. Newcomers are better off with a finished, scented LAL perfume. At $29.99 it's a low-cost way to test the waters.
