Analysis Details

Note: While Bodybuilding.com claims 2,148 reviews, we counted 1,889 available on their site.

Fail Rating Trend

  • 12%
  • Created over 15 days

We counted 1,889 reviews for this product over the span of 1,664 days, an average of 1.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 6 or fewer reviews on any given day.

However, we see the following 15 days exceeding this threshold:In total, we found that 222 reviews were created on just 15 days. The reviews on these high volume days have rated this product an average of 9.6 while reviews from other days have rated this product an average of 8.9. Based on our statistical modeling, the discrepancy in average rating between these two groups is significant enough to believe that the difference is not due to random chance, and may indicate that there are unnatural reviews.

Fail Brand Repeats

Brand Repeaters


564 of the 1,889 reviewers have reviewed other products for this brand. While this is more Brand Repeaters than we'd expect to see, the discrepancy in ratings between the Brand Repeaters and non-repeaters isn't significant enough to rule out the possibility of it being due to random chance.

Brand Loyalists

Warn Deleted Reviews

We discovered a total of 56 deleted reviews for this product, with an average rating of 9. Even though deleted reviews don't affect the average rating, the fact that action was taken to delete reviews raises some red flags about the integrity of the reviews for the product as whole.

There are a few limitations to keep in mind regarding the Deleted Reviews test:
  1. We don't have a magic ability to collect every single deleted review; we can only identify reviews as deleted if we collect them on one date and then notice they are no longer visible on a subsequent date.
  2. We have no information on reviews that were never published in the first place.
  3. We also don't know why these reviews were removed. It could be action from the platform, personal decision by the review author, part of an entire account closure, even some data error on our part, etc.
