Note: While Bodybuilding.com claims 4,810 reviews, we counted 4,173 available on their site.

Fail Deleted Reviews

We discovered a total of 282 deleted reviews for this product, with an average rating of 8.3. 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.

Fail Rating Trend

  • 3%
  • Created over 11 days

We counted 4,173 reviews for this product over the span of 2,364 days, an average of 1.8 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 8 or fewer reviews on any given day.

However, we see the following 11 days exceeding this threshold:In total, we found that 141 reviews were created on just 11 days. The reviews on these high volume days have rated this product an average of 9.1 while reviews from other days have rated this product an average of 8.5. 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.
