Revcontent Ads can't be approved

I am going to test a Nutra offer for weight loss, but the Landing Page keeps failing to approve, I have modified the Landing Page but it still fails to approve.

The Landing Page is a copy of a competitor's and many competitors are using this Landing Page, but why is my ad not approved.



Reason for rejection:
Advertorial Violation - False Comments
Weight-Loss Violations - Missing substantiation
Weight-Loss Violations - Unverified testimonials
Weight-Loss Violations - Unverified weight-loss claims
Time & Supply Claims

Many of my competitors' Landing Pages use countdown timers and have a lot of comments, so why are their ads not being rejected while mine keep getting rejected.

Do you guys have this problem?

Thank
