“Contrary to what would seem obvious, the SPS is as effective at 3 x 30 minutes daily as the dynamic is at 8~12 hours daily. Combine that with heat and I think we’re on to something.” - That’s amazing if correct. It would suggest that the penismaster (weight hanging, pumping, etc.) are all inefficient and that instead a simple device which you just screw out to a certain length (providing the constant strain) would be best (like Piet’s homemade stretcher). Of course the question then becomes how much strain is needed - which one can get a feel for with the stress-strain plot.
About the question of heat, I was just throwing out the possibility that too much heat (applied over long times) might hinder growth, though the HSPs are quite interesting and may be why some people have success removing discoloration by heating and then massaging the discolored areas.
