My thigh pain has been bothering me to the point that I could not squat without pain yesterday, and that was a light day. After a lot of experimenting and some knee pain I was able to do high, narrow-stance SSB box squats with 225 for 20 reps. Still had thigh pain but it was manageable. I will always find a way. 

Super-setted that with 225x20 deadlifts. First 10 regular, last 10 stiff-legged. Attacked next the upper-body with heavy band presses for 4 sets of 15-20 and super-set that with pull-ups. At the end, I did a 40-second pull-up. I have a minute in me, but the eccentric part started to strain my biceps as they lengthened and that'd be the dumbest thing to injure one of them on.
