I’ve used Xist quite a bit over the last seven years or so, along with a fair number of other pheromone products from Liquid Alchemy Labs, Alpha Dream, etc.
I was first made aware of Sub Club from a post on a pheromone discussion forum.
I wore pheromones pretty much every day from August of 2013 until the Covid crisis hit, and at that point they didn’t seem as relevant, but I am shifting back into using them.
I do find they can smooth social relations, sometimes in amazing ways, but sometimes, also, they seem to have little effect. They are more catalyst than driver, as you would expect, and if you are not in a state capable of making use of them not much will happen.
