I’ve been experimenting with shorter pulse cycling using a pulsator that I just recently put together (see my post towards the end of the thread below), and I think I agree, that cycling between 3" and 10"Hg with cycles lasting no longer than maybe 2-4 secs, combined with heat (I use a pad), seems to making a much bigger difference in maintaining length and girth gains than longer cycles of low pressure, which really just creates a temporary edema. Vacuum cannot be maintained long enough for use as traction without getting a blister, bruise, etc, but short cycle stretching over and over is working much better for me.
I’m also using a silicone sleeve from ABSilicone to control any edema swelling and combined with the pulsation, I can do sessions as long as 60 mins without any noticeable negative effects, though I’m not sure if there’s any benefit going that long. I suspect multiple shorter sessions per day, say 3 at 30-40 mins each, is better. After a good session and I remove the sleeve, I’m astonished at how long I seem to stay elongated, thick, and firm.
On a side note, some years back I actually read Willem Kannengießer’s book on penis pumping for health and growth (in German), and in it he mentions that 3 sessions per day at up to 40 mins each combined with massage, was most effective.
Another side-effect I’ve noticed is, approximately 6 hours later, I seem to be able to get solid erections easily (I’m 60 and have mild ED), so if I do a session in the morning, I have to watch my thoughts during the day like I’m back in 8th grade again(!), and if I do a session before retiring at night, I’ll wake up in the night with wood so hard it’s almost uncomfortable, which is probably why it woke me up.
(I’ve wondered medically what’s going on here. My guess is that short cycle vacuum stretching combined with heat is indeed stretching while simultaneously circulating blood and fluids in and out of the tissues, which is basically rejuvenating).
