Analysis Details
Note: While Bodybuilding.com claims 187 reviews, we counted 163 available on their site.
Fail Deleted Reviews
Deleted Reviews
We discovered a total of 13 deleted reviews for this product, with an average rating of 10. 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 Suspicious Reviewers
Suspicious Reviewers
One-Hit Wonders
50 of the 163 reviewers have only reviewed this product. This is an excessively large percentage of One-Hit Wonders which may indicate unnatural reviews.
Never-Verified Reviewers
52 of the 163 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
41 of the 163 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
26 of the 163 reviewers have written multiple reviews but posted all of them on a single day. The Single-Day reviewers have rated this product an average of 10.0 while all other reviewers rated this product an average of 9.4. 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 Reviewer Ease
Reviewer Ease
The ease score is the average rating for all reviews that a given reviewer submits. The average ease score for reviewers of this product is 9.2, while the average ease score for reviewers in this category is 8.8. 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.

Warn Unverified Purchases
Unverified Purchases
86 of the 163 total reviews for this product are unverified purchases. While this is a higher percentage of unverified purchases than we'd expect to see, it does not appear to have a significant impact on the overall rating.
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.
Warn Phrase Repetition
Phrase Repetition
Reviews that contain one of these phrases are NOT necessarily devalued; read more about how this test works here.
27 of the 163 total reviews for this product use substantial repetitive phrases between them. While this is more than we'd expect to see, the discrepancy in ratings between the these reviews and reviews without substantial repetitive phrases isn't significant enough to rule out the possibility of it being due to random chance.
