Participate in FSF Challenge

If you don’t know yet what is FSF Challenge, you can find out more from HERE

We want to show that our natural and good-looking products are really as effective and as convenient as we have said them to be. That’s why there are a few people every month trying the FSF Instants for 30 days and writing their experiences afterwards. We’re especially looking for people who in one way or another live a demanding life and could use a bit more energy, help to calm down or to fight diseases.

Would you like to take the 30 day FSF Challenge, or do you know someone who is a perfect fit for it? If so, you can apply for it by sending an email to info (at) and tell us why you should be chosen.

Notice: Applying for FSF Challenge doesn’t guarantee that you will be approved. We will let you know if you are approved.
