Does GainsWave provide patients with permanent results?

It’s true that GainsWave typically requires several sessions before you see optimal results, but those results do last—in fact, it’s one of the longest lasting ED treatments available. Every patient responds differently to treatment, so the immediacy of results and the number of sessions needed varies. Most patients require 6–12 treatment sessions to achieve the results they want, and some start seeing the effects after just 1 or 2 sessions. Once your treatment is complete, results can last up to 3 years.

So give yourself at least 90 days to decide on effectiveness. Some people get results right away. Consider combining it with P-shot. I think it all depends regarding maintenance. I would repeat at least once every year or whenever you start noticing a difference.
