Why there are no ratings on this page
This site sells nothing and collects no customer reviews. A star rating without a verified purchase, without a date and without any statement of how it was collected would be worthless and legally vulnerable in advertising. So there are none here.
What you will find instead is guidance on how to read reviews found elsewhere and how to spot fabricated ones.
How to spot implausible reviews
Warning signs: only top marks with not a single critical voice, texts of similar rhythm and length, reviews without dates, a burst of reviews within a few days, names without verification, and wording that describes symptoms and recovery.
A second signal is substantive. If reviews describe effects the manufacturer would not legally be allowed to claim, they are serving the same purpose as unlawful advertising.
Why personal experience is hard to interpret
Musculoskeletal symptoms fluctuate naturally. Starting during a bad phase makes the subsequent return to baseline feel like an effect. Expectation effects are strong where endpoints are subjective, as pain is.
That is exactly why serious research uses control groups. A single testimonial cannot fill that role, however honestly it is meant.
Making your own observation usable
Fix a start date, note intake, tolerance, physical load and sleep, and change as little else as possible during that time. Record how the two weeks before the start went as well.
This record does not replace a study, but it is considerably more reliable than a recollection after eight weeks and helps you decide whether to continue or stop.
