Because of the slowed diffusion I can get away with wearing quite a few "inches" of LP phero perfumes, depending on the fragrance. For PheroGirl and Tantric Butterfly, for example, at least 12 inches and sometimes more, applied to neck, torso and arms.
Try putting some on your forearms and then wiping it on your hair - hair diffuses madly especially if it's swinging around.
I don't think the oil-based pheros are as likely to blow you (or others) out of the water, compared to alcohol-based sprays.
