Participants will receive a bottle of Slim21 to help them reach their summer body goals. The bottle is not to be opened until the challenge begins on the morning of the 14th of August. Participants will take 1 tablet a day for 21 consecutive days, ending on the 03rd of September.

This challenge will be judged by the Slim21 panel of judges based on the overall % of weight lost and the before and after photos.


Participants are required to send progress pictures on specific dates during the challenge, giving us all a chance to witness their amazing transformations! These dates and the terms and conditions around the photographs will be communicated to participants separately once finalised.
