The T series it the test series.
They are chemical that have come from an earlier series, the Putative Phase 1 trials, in which we tested over 70 chemicals, mostly on people who wouldn’t know what a pheromone was if it bit them. I think we may have just hit 80.
Everything in the test series shows some pheromonal activity, or is at least claimed to be a pheromone by another company.
TAC (and TAK which is similar), for instance, have been requested by some clients. We didn’t bother to test them as putatives very long, although I’d have to say they’re not exactly the most exciting pheromones in the world.
TAA, on the other hand, is very exciting. The full nature of it isn’t know yet, but I’ve yet to see it really spoil a mix. If I had to describe it with one word, I’d almost call it: Manpolish. Silly, but, hey, we all like and understand a good car wax 
It seems to give you kind of a sheen, and a focused confidence.
I appreciate your time, as well.
