Analysis Details

Note: While Bodybuilding.com claims 217 reviews, we counted 201 available on their site.

Fail Unverified Purchases

107 of the 201 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 10.0 while the verified purchasers have rated this product an average of 9.3. 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.

Take-Back Reviewers


20 of the 201 reviewers have had at least one of their past reviews for another product deleted. While this is more Take-Back Reviewers than we'd expect to see, it does not appear to have a significant impact on the overall rating.

Single-Day Reviewers


31 of the 201 reviewers have written multiple reviews but posted all of them on a single day. While this is more Single-Day Reviewers than we'd expect to see, the discrepancy in ratings between the Single-Day Reviewers and all other reviewers isn't significant enough to rule out the possibility of it being due to random chance.

Warn Deleted Reviews

We discovered a total of 8 deleted reviews for this product, with an average rating of 9.9. 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.

Warn Rating Trend

  • 8%
  • Created over 5 days

We counted 201 reviews for this product over the span of 2,126 days, an average of 0.1 reviews per day. If these reviews were created randomly, there would be a 99.9% chance that we would see 2 or fewer reviews on any given day.

However, we see the following 5 days exceeding this threshold:In total, we found that 16 reviews were created on just 5 days. Although any days with a larger number of reviews than expected is suspicious, the discrepancy in ratings from reviews created on these high volume days and reviews created on other days isn't significant enough to rule out the possibility of it being due to random chance.
