Analysis Summary

The reviews show a moderately suspicious pattern with several red flags. The product has an extremely high 5-star concentration (11 out of 15 reviews are 5-star, 73%), which is unusual for legitimate products. Multiple reviews exhibit classic fake review characteristics including exaggerated results ('tons of growth' in barely a month, visible nail growth in just 4 days), generic praise without substance, and repetitive language patterns. However, there are also authentic-seeming reviews with specific details, dosage concerns, and mixed ratings that balance the assessment. The presence of Japanese language reviews and detailed negative experiences suggests some genuine feedback exists.

Understanding This Analysis

What does Grade D mean?

This product has significant review authenticity issues. Many reviews show patterns consistent with fake or incentivized reviews. Exercise caution.

Adjusted Rating Explained

The adjusted rating (3.50 stars) represents what we estimate this product's rating would be if fake reviews were removed. This product's adjusted rating is lower than Amazon's displayed rating (4.40 stars), suggesting positive fake reviews may be inflating the score.

How We Detect Fake Reviews

Our AI analyzes multiple factors: language patterns (generic vs. specific), reviewer behavior (history, timing), temporal anomalies (review clusters), verification status, sentiment authenticity, and statistical outliers. No single factor determines a review is fake - we look at the combination of signals.

Important Limitations

No automated system is perfect. Sophisticated fake reviews can evade detection, and some genuine reviews may be incorrectly flagged. Use this analysis as one data point in your purchasing decision, not the only factor. Reading actual review content yourself is always valuable.
