Well, since Eq is going to be in your system for 3 weeks anyway, I don't see the point in stopping. 10-14 days is a while, but there is no true benefit to stopping now (unless he plans to end his cycle and take some time off).
I would take 5 days off of working upper body, then I'd buy some butterfly bandages, and put those suckers on the stiches to help hold the skin together, and begin working out again (a little lighter than normal), and see how it works.
It should be obvious whether the the workout is putting too much strain on the stiches. The butterflies will help keep the skin together, and less stress on the stiches themselves.
I'm not sure how long your cycle is, but I'm assuming 8 or 10, so you are at week 4 or 5, which means the Eq has barely (if at all) kicked in at this point. IMO, he would have better results if he just took some time off, instead of stopping his cycle (and restarting it down the road).
