Analysis Details

Note: While Bodybuilding.com claims 73 reviews, we counted 58 available on their site.

Fail Deleted Reviews

We discovered a total of 8 deleted reviews for this product, with an average rating of 8.9. 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.

Fail Unverified Purchases

47 of the 58 total reviews for this product are unverified purchases. The unverified purchasers have rated this product an average of 9.0 while the verified purchasers have rated this product an average of 6.9. 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.

Unverified purchases may be the result of Kindle Unlimited readers, buyers who didn't pay full price, or reviewers who did not purchase the product at Amazon. Read more about our Unverified Purchases test.

Fail Brand Repeats

Brand Repeaters


23 of the 58 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


14 of the 58 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.

Fail Suspicious Reviewers

One-Hit Wonders

Never-Verified Reviewers


31 of the 58 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.

Take-Back Reviewers


13 of the 58 reviewers have had at least one of their past reviews for another product deleted. This is an excessively large percentage of Take-Back Reviewers which may indicate unnatural reviews.

Single-Day Reviewers

Warn Rating Trend
