Just to provide a little more clarity for you…
There are two sections to the store.
Consumer products… These are the to-go mixes and the mens and women’s products like Instant sexiness or AMMO IO IH ect ect .
Then there is the advanced user section. his section if for serious users and people who want to participate in the testing of mixes and putatives.
There are three major section in the advanced section.
Experimental mixes are more then one putative/pheromone mixed together to create a certain effect. They have a MX followed by a number.
Putatives are single molecules that are suspected to act as pheromones. (They are in testing). These have a P followed by a number
Experimones are basically the single molecules they know act pheromonally.
You will also see people refer to the T-series. These are also single molecule mones that begin with a T. TAH TAL TAA TAC TAF TAC. Why they named these differently is a mystery only AD can explain LOL
This part gets a little confusing. Some people write 2X to indicate they used 2 sprays.
However most of us say 2X to mean we bought our product with 2 times the strength of pheromones in it. 4X would be 4 times the amount of mones. You can usually figure it out by reading there whole post. If not just ask them to clarify it.
Copulins are only made by females. They are the vaginal secretions from young fertile females. (synthetic of course) They dont sell them here any longer.
LS is another pheromone company. Love Scent. They sell copulins called EOW. You dont really need them being a male but some guys like that just got laid effect.
This post will help you with even more great info to get you started
Happy reading
