If you think it really is a pec tear, seek medical advice and get a scan(probably an ultrasound) to assess how bad the damage is. Other wise if you deny it, keep on training don't be surprised if you get a complete rupture.
When you are off a steroid cycle you are supposed to deload a bit: weight, volume, intensity and even frequency.
Not really much point trying PR's when your not on a cycle either. I try to consolidate my strength gains when not on a cycle, rather than expect massive increases like you get when on cycle.
What are your goals? Strength/powerlifting or bodybuilding. If its bodybuilding you don't need to bench heavy weight, low reps.
If its powerlifting that's not my field of expertise, but they cycle their poundages and change exercises, so even though they are training to improve their competition bench, they won't be doing full range reps all year round.
Remember train smart, not hard.
