What settings are recommended for ShockWave Therapy Device?

I have bought this ShockWave Therapy Device.

Apparently it works for improving erections.

Question - what settings in terms of Frequency and Intensity would be optimal settings for ER treatment?

And what gel or oil you use as lubricant for electricity to work?

You’ve asked the same question 7 times now. All the information is available to you if you read through the threads and the referenced medical studies. There is no guide and there is no single recommended protocol, although they do seem to be grouped in a close range. The various medical studies report the results of the treatment protocols they used.

You will need to decide which exact settings you use. You may decide to change your settings and compare the results from your previous efforts and decide which is best for you. I did this, still do, as has Dick Limpen and Whacky76 and others.

Fixing my own ED with shockwave therapy: Treatment protocol

I suggest two treatments per week for 3 or 4 weeks, depending on your response, and you decide what that is, then take a couple months off to allow the treatment to work and your penis to rest.

I am now in a rest cycle and will begin my next treatment cycle soon.
