Pheromone dosage response curves

I have a question regarding adverse effects. People have talked about “self effects” of pheromones, OD-ing, and head rushes. Also, there was a post/article about how nursing mothers use (natural) pheromones to bond with their newborns: Using Pheromones for Attraction and Bonding

Are there potential negative, long-term side effects? Over time, one will become used to the pheromone signature and might have to up the dose or mix it up a bit to get the same effects, but are there any serious ones?? After readings the posts (my package comes in the mail tomorrow!) it seems pheromones are very potent and very serious stuff- very drug-like. Just wondering if you (or anyone) knows anything about long-term effects (eg. like messing up neuropathways/receptors, any effects while breast feeding, etc.). Thanks!
