Analysis Details

Note: While Bodybuilding.com claims 815 reviews, we counted 732 available on their site.

Fail Deleted Reviews

We discovered a total of 56 deleted reviews for this product, with an average rating of 7.6. 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

  • 17%
  • Created over 19 days

We counted 732 reviews for this product over the span of 1,916 days, an average of 0.4 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 19 days exceeding this threshold:In total, we found that 126 reviews were created on just 19 days. The reviews on these high volume days have rated this product an average of 9.0 while reviews from other days have rated this product an average of 8.3. 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


237 of the 732 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


126 of the 732 reviewers have reviewed multiple products but half or more of their reviews are for this brand. This is an excessively large percentage of Brand Loyalists which may indicate unnatural reviews.

Never-Verified Reviewers


385 of the 732 reviewers have never written a verified purchase review. While this is more Never-Verified Reviewers than we'd expect to see, the discrepancy in ratings between the Never-Verified Reviewers and reviewers who have written at least one verified purchase review isn't significant enough to rule out the possibility of it being due to random chance.

Fail Skewed Helpfulness
We examined the average net helpfulness score of negative reviews against the average net helpfulness score of positive reviews. The net helpfulness score is the number of times a review has been marked as helpful minus the number of times a review has been marked as unhelpful. We found that the negative reviews had an average net helpfulness score of -0.1 while the positive reviews had an average net helpfulness score of 0.1. Based on our statistical modeling, this discrepancy is significant enough to believe that the difference is not due to random chance, but possibly due to influence of unnatural voting patterns.

Warn Unverified Purchases

542 of the 732 total reviews for this product are unverified purchases. While this is a higher percentage of unverified purchases than we'd expect to see, the discrepancy in ratings between the unverified purchases and verified purchases isn't significant enough to rule out the possibility of it being due to random chance.

Warn Sample Reviews

44 of the 732 total reviews for this product mentioned the word "sample" within their review. This is more than we would expect see; the presences of any reviews that mention the word "sample" indicates that there may be more, since not all reviewers will disclose that they used a sample within their review.
