London, NPE (VED and extenders) has been proven effective on Peyronie disease more than meds.
If vacuum pumping is different from other forms of PE, the natural deduction would be : I’ll try other forms. Instead you want to believe at any costs that there is some magic pills out there.
Let me ricapulate for you : androgens - they have tried by many and no gains so far; DMSO, not even weak anectodal evidence so far that it works for gains; erection drugs - have been a failure as well, for gains, and beside that, what they are supposed to do? DTW’ post nailed it.
