Even

after all these years in the business, I am still not sure what to make of this -pheromone smell is a question of

purity- position. I have the highest oppinion of Stone Labs and I know they stand on that platform or used to, but

as far as I can see, some pheromnes have a strong smell to them and some do not. You can\'t get that smell out

without destroying the pheromone. I will go so far as to say that that smell is your sign of purity; your signal

that you have the real deal there. Androstenone smells like urine for a reason, and that reason is that urine

smells like urine because of the androstenone in it. Urine smell and androstenone go together like water and

wet.

Animals smell the urine left by other animals and they can tell whether the animal is male or female, young

or old, agressive or passive, sexually active, and on and on all because urine has pheromones in it. I would be

very surprised to learn that you could somehow purify urine and expect it was still going to be able to do its

pheromone magic.

Specifically, about the AFA/Edge comparison: AFA contains NOL which in fact has very little

smell (regardless of whether you \"purify\" it or not) and Edge contains no NOL but rather other pheromones that

obviously do add to the \"bouquet\" as it were of the final brew. So, after years of hearing the occasional

argument that pheromones smell like urine because they have not been purified enough, I have yet to see/smell any

proof of that and simple reason would indicate otherwise.
