About Oupeptide Test Results From Finnrick
Oupeptide 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 10 products and 192 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) and customer satisfaction reports with sub-scores that provide additional context. Use the table above to review purity, quantity accuracy, consistency between batches, and any notable outliers surfaced in Finnrick testing data.
