My opinion and probably that of every hardcore long time female user of pheromones is that copulins are the #1 essential signaler in a woman’s arsenal for sexual attraction. No other pheromone I have ever used (and I have used alot) evokes such a strong sexual attraction.
Its not just the scientifically proven rise in testosterone that SK mentioned thats at play. Copulins signal youthfulness especially for women who are older, approaching menopause or are on the pill. The AJ study show men rated women with higher cop signatures as prettier or more attractive then those with low copulins signatures.
To many experiences to write here really so I will condense it. Men show more interest when I use copulins. They flirt more, make eye contact more, use IOI body language more and they hit more. I find that targets are not age or race dependant. I find there are two types of men. Ones who are more laid back in nature and hold back there response till appropriate and those who are more blatant and aggressive who hit hard and fast.
There are times when I have worn copulins around a person who seems unaffected at all only to find out weeks later at a party that I was driving them to distraction (in a good way) all this time.
There are times when I have worn it when they have worked to well and I have been literally stalked. (search my name and copulin mall incident)
If we compared it to mones emitted in the animal kingdom it would be the equivalent of sending the heat signal or being in heat. However human males, as randy as they may be do have a logical side and while it attracts them it doesn’t mean every single male will be into you and ignore there other preferences and requirements in attraction.
When I first used copulins I had a tough time finding a dose that affected my husband. I found out I was using to little for my age and because I was on the pill. The pill stops ovulation which stops the production of copulins. The very thing that makes it so your more free to have sex also makes men less attracted or aroused by you pheromonally. Ironic I know LOL.
Unless testing I always use a little copulins. Just enough to increase that feminine sexy vibe without causing to much distraction. When I want a heavier more blatant response with hubby then I kick it up to my normal dose. His reactions have run between more interest and attention to blatant sexually aggressive depending on the environment we are in at the time.
On the smell…
I have worn some of the most rancid smelling copulins ever made. I have the earlier formulas that are concentrated. You could smell those 20 feet from the mailbox when they delivered them. ( I gave the mailman a huge tip that year LOL)
The brands you get now are much less offensive. They still stink but not half as bad. I have worn copulins with and without cover. Fully expecting to get a “eww you stink” reaction when I was out only to be shocked by the number of “Mmm you smell so good” reactions from both males and females. The only bad reaction on actual smell I got was when my (70 something at the time) mother smelled them. She mentioned I smelled like a french whore LOL I never met a french whore so I cant tell you what that smells like, I asked her though and she said they smell like sex.
I did report once on my parents, they came over for a picnic and my mother was in my room with me chatting and used one of my perfumes she liked before I could stop her. I had spiked that particular one with copulins. Later that day I caught her making out with my father who was pushing 80 at the time on the back deck. They have always been affectionate but in all my years I have never seen them make out. Kiss yes but this was not just a kiss LOL. (snort) 
You definitely have to learn to use them, it takes practice to cover and you need to get used to that feeling of having a foreign substance on you. I believe women recognize there own copulin scent and when you wear them from a bottle consciously you know they are not yours. They never really match you perfect like your natural ones do which is not the case for mones which are all molecularly the same. Its probably why women always have that six sense when there guy is cheating even when they hide it well.
Many guys I know who have used cops while in a relationship have ended up in fights or on the couch with there partner pissed at them for no good reason.
AD stopped using copulins in there products a few years ago. Unless your buying a preowned bottle and I missed your mention of that your getting Instant sexiness B (no cops) from AD now. They dont sell A anymore.
