Perhaps not the case. I get excellent results w/ a far lower dose than most ppl use…20 mu vs. 100 mu. FYI, I’ve used both scented and unscented. The scented version seems to project the molecule better and I’ve received numeous comments about a vinegar/urine smell when using the unscented. A cover scent doesn’t seem to work as well as having the fragrance premixed w/ the pheromones.
