Gut theory? It's just the first one he personally came into contact with, and being autistic, decided it was the best. I recall early one, when he first got into it, him mentioning "There are other pheromone products out there...", so he's aware they exist, but I'm just assuming Bond Tactical was the first he actually stumbled across as claimed for himself.
A lot of that overpriced dogshit tends to use over the top MANLY MAN™ advertising, which you know works like magic on retards like him.
Duke Cannon fucking rules. But you can't watch this dumbass commercial and tell me it's not intentionally targeting no confidence having mongoloids.
