This sounds more like an underlying condition exacerbated by drugs rather than a purely drug-induced phenomenon. You could probably get this addressed pretty easily.
For example, it is not unlikely for a person with an underlying anxiety disorder to experience heightened anxiety symptoms when he or she ingests caffeine. Along the same lines, schizophrenics who chug a pot of coffee can induce a psychotic episode. While there is a phenomenon called caffeine-induced psychosis, where people with no underlying issue experience psychosis after exposure to tons of caffeine, it's very rare, to the point that it hasn't been well documented or occurred often enough to be well-described. On the testosterone side of things, there are compounds that are known to make people go nutty, but modest doses of test aren't among them.
If you tend toward paranoid ideation anyway, it's much more likely that caffeine or test is pushing you in that direction rather than causing fully novel thought patterns. Treating whatever anxiety you have organically will probably take care of whatever this is.
Also, I agree about those stimulant-packed preworkouts. I could take in 500 calories of fingernails that I chew through from the anxiety those things can crank up.
