I would like to know how many days I must be applying the frequencies, how many sessions for a specific treatment, at least.

The total time for successful sessions include:

a) the time to find out the best programs.

b) the time to clear the problem.
Usually "a" is a lot longer, and here practice and intuition helps a lot. In fact many times you get stuck into Phase "a" without being able to switch to phase "b". As a general rule, if you see no results for a progran in 3 days, better switch to another one.
If you have found the right program, the condition can be resolved in less than 5 minutes, or take a whole month or more.
During the last 25 years, I've seen how a severe cold clears in less than 3 minutes, and also I've seen a PSA going down from 12.9 to 2.9 in one month, among many many other successful stories.
BTW, I've also seen many times no effect at all, no matter how hard I tried.
