Difference between comfort Phero's

OK, so I was looking up info on numerous products when I happened upon this site, among them what Liquid Trust which while not technically a pheromone is touted as having phero like effects. I come here and then the androtics order site and I see Instant Openness, Instant Honesty etc. and I’m wondering what the differences are between these products as in many ways they sound like they’re designed with the same effects in mind
