Note: While Bodybuilding.com claims 197 reviews, we counted 194 available on their site.

Fail Rating Trend

  • 20%
  • Created over 6 days

We counted 194 reviews for this product over the span of 406 days, an average of 0.5 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 4 or fewer reviews on any given day.

However, we see the following 6 days exceeding this threshold:In total, we found that 39 reviews were created on just 6 days. The reviews on these high volume days have rated this product an average of 9.8 while reviews from other days have rated this product an average of 7.7. 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

Warn Deleted Reviews

Warn Sample Reviews
