Hey i bought TAC from the product line and it says molocule C on the bottle Did they send me the wrong stuff or is that how it comes and what its really called?
No that is TAC, have fun.
TAC’s label is Molecule C, just like TAA is “Molecule A” etc… 
thank you was kinda worried there for a min.
Good! Now that that’s straightened out… let’s get some testing going!!! 
And HAVE FUN doing it!!!
Anything with the “TA” prefix are usually referred to by Molecule A, C, F, H, K, L.
Respectively.
What you purchased typically are used by people who have had at least some sort of pheromone usage that’s already proven effective (anything from the “Instant” series, AMMO, and A314.)
You do what you want and you may be a quicker learner than most people but it’s hard to base reactions if you haven’t honed in your senses to single molecules at first.
Either way good luck, and start small and work your way up till you find what’s called a sweet spot.
However for your own benefit, I don’t know if you ordered anything else but I would start with the commercial products first instead of Putatives/Experimones.
