About GrayPep Test Results From Finnrick
GrayPep is a peptide vendor with multiple products tracked in the independent testing dataset collected by Finnrick. This page compiles recent, batch-level test results across 1 product and 4 tests, including scores, test dates, batch IDs, and lab details. This enables you to compare quality over time, not just marketing claims.
Each tested sample receives a 0–10 score, with 10 being the best possible value. It is the total of three components: purity (0–4 points), quantity accuracy vs. the label or batch claim (0–4 points), and batch information quality (0–2 points).
When several test results are available for a product and vendor pair, you’ll also find a Finnrick Rating (A–E, where A is best and E is worst, X if an insufficient number of tests is available, or F in rare cases of documented and widespread fraud). Use the table above to review purity, quantity accuracy, consistency between batches, and any notable outliers surfaced in Finnrick testing data.
