MASKED is one format. ULTRASONIC is an alternate format.
Imagine that you buy some Vitamin C.
It may be in tablet form.
Or it may be in syrup form.

Either way it’s the same vitamin C. It’s just in two different forms.
Why?
Because some people prefer or respond better to tablets. Other people prefer or respond better to syrup.
Now, your vitamin instructions say:
“Take 90 mg of Vitamin C each day.”
90 mg of Vitamin C equals one tablet.
90 mg of Vitamin C also equals one spoon of syrup.
So, if you’re following the instructions and taking the prescribed amount of Vitamin C, then each day you will take either one tablet or you will take one spoon.
Remember: they are the exact same Vitamin. You choose one based on your preference and/or based on which form you think works better for you.
But whichever form you choose, you should still stick to the recommendation of taking 90 mg per day.
So on each listening day, you choose to play one loop (i.e., one repetition or one play) of either the MASKED file or the ULTRASONIC file.
Which you choose is up to your own preference. Some prefer Masked and others prefer Ultrasonic. So Sub Club provides both.
Now, for a more advanced situation, we go back to the vitamins:
your doctor or nutritionist might tell you, “In your case, 180 mg is a better dose for your needs. So take that for a month and then go back down to 90 mg.”
In this case, you’re taking 180 mg of Vitamin C. So you could take:
- 2 tablets of Vitamin C
- 2 spoons of Vitamin C
or
- 1 tablet and 1 spoon of syrup
Again, that would be up to your preference and your judgment.
Whatever combination you choose, you’ll still be getting 180 mg of Vitamin C. And that’s the point.
So, one “loop” or play-through of your subliminal is 90 mg of Vitamin C. Take it as Masked (the tablet) or Ultrasonic (the syrup). But the important thing is that you stay within the recommended dosage: 1 or 2 loops, every other day.
Every 3 weeks you take 5 days of non- listening. This gives your body-mind necessary time to process and digest what you have been taking in.
