Or possibly try one set at 95kg just to see how it goes. If you only get a couple reps then back off the weight for the next sets. You have no mechanical injury that you're risking making worse here, even if you're feeling weak I'd be surprised if you couldn't at the very least grind out one rep at 95 kg to see how you're feeling. Also curious what program you're on if you're doing 4 sets here.
