Here’s another. No extra charge. 
People often overlook the fact that putatives (and even perhaps the molecules listed in the ExperiMone section aren’t promised to be stuff naturally on the skin. I can’t remember if DHEA S is on the skin. -eNone is on the skin. As I recall, it’s poorly soluble in water. The purpose of sulfation is to take the DHEA and make it soluble in urine. The same would be true of saliva. Imagine if P75 does not occur on the skin naturally at all. How would people react if they smell a mone that came from saliva or urine. If the brain has receptors, it would react. But it would be freaky, alien stuff. The brain has opiate receptors. It will react to the opium poppy. But something like an opioid oxycodone hits the same receptors but never existed until man made it. P75 is like LSD, hella potent at just micrograms. So, apparently, we’ve evolved to respond to women’s pee. Note that sulfates are very heavy and highly electronegative molecules. I’ve never been crystal clear what impact that has on mixes. However, DHEAS is heavier than androstenone. Oxygen is a way bigger atom than hydrogen. More electrons. More charges. Look at the pics and see if you don’t think the little hydrogens in alpha nol, for example, get tugged quite a bit by the much bigger Oxygen. Fat chance finding any science discussion about that online!
