Using shock therapy with Extension exercises.

Is it okay to do shock therapy ( something like the Phoenix Acoustic Wave device ) then follow up with using an extension device?

Li eswt units are for treating ED, not for PE. A component of the treatment regime is to pump after eswt treatment. This insures fresh blood movement throughout the penis.

Will it hurt to extend after a treatment? I think it unlikely.
Will you get gains from it? Very unlikely from the eswt treatment, possibly from extending.

FYI I have ED and after paying a dr for expensive gainswave treatments (which do work for ed), I purchased my own unit and have been self treating for a couple years or so.

ESWT not only will not work for penile growth, but it also shrink it.

Read Kyrpa’s thread, he did extensive testing with ESWT after growing his septum with US therapy.

Will ESWT work for your erection quality? Yes.

I’ve used an eswt for a few years and never had shrinkage from it.
