The short answer is no.  You do have to pay for shipping and handling for the product which comes to about $6-8, depending on your location.  Additionally, FRS will enroll you in their automatic replenishment system that will send out a new supply of product each month.  However, you can cancel this service by contacting FRS at any time and they have a very generous return policy, outlined below.

The FRS Company stands behind FRS healthy energy products.  If you’re unhappy with your purchase for any reason - even if you’ve used all of the products - you can return the products or the empty containers for a full refund of the purchase price minus shipping and handling.

They even provide a return shipping label on each packing slip.  You still have to pay to ship the products or empty containers back.

So, while you do have to pay for shipping and are enrolled in an automatic replenishment program when you sign up for the free trial, you can cancel the service anytime, without any difficulty, and the shipping is a minor cost to try out a great product.
