Why is it the only one that is hidden from the rest of the population? What chemicals are in it exactly that make it so special?
its a secret 
What ever is in that putative, it has some potent effects. No need to say more lol.
It is only restricted because current popularity has caused a run on the product and AD is experiencing supply problems. This happens every so often, when a rash of good reports increase interest in a particular molecule/mix - a few months back it was P75, last year it was MX297, Meo-EST and so-on.
So until that is sorted, sale is limited to reporting users (search it!) who will give feedback on how they use and get on with it.
Putatives are single suspected pheromones not a mix of them. P83 is probably one of the more popular ones. I dont think they hide it but they do make it difficult to get for the non reporting user.

Ahhh thank you all that was very helpful.
It is costly when a rash of people who have no intention to properly report on a rare molecule start hoarding it. Unfortunately this was the only way for us to ensure that it is available to people who have proven they can utilize responsible reporting techniques and aren’t afraid to report in on their results.
It could change when we restock, of course.
Non-reporters see a lot of reporters saying it works and they get narrow minded and forget there are tons of other amazing molecules out there. It’s like a lot of people say granny smith apples are great and suddenly people forget red delicious exist.
That makes a lot of sense. Thank you!
