Testosterone supplementation is very unlikely to be causative for what you're running into. Test is incredibly mild in psychological effect (unless you're deficient). This kind of stereotype comes from trenbolone, but I think you shouldn't under-estimate the intersection of steroid users and cocaine users. It's bigger than you might intuitively guess.

Aggression certainly isn't limited to tren, high testosterone & DHT levels in general increase it. This is well understood.

Using TRT for its prescribed effect (baseline "normal" range) likely won't have any impact on this but taking it to go above normal levels certainly could.
