Using Percocet for premature ejaculation is a pretty bad workaround. Yeah, opioids can blunt orgasm, but they also bring dependence, sedation, and a bunch of other baggage that has nothing to do with fixing the actual issue. If the question is what makes more sense practically, dapoxetine is at least a PE-specific option people look at instead of messing around with opioids. I would keep it simple and compare the actual active ingredient, seller transparency, and packaging details rather than chasing random forum hacks.
