Launch with Finnrick
Some of the samples listed on this page were submitted by their vendor, as part of the Launch with Finnrick vendor support program.
The program is designed to help vendors get listed on the Finnrick web site while protecting the integrity of our rating system.
The vendor submitted four samples per product, two of which were tested by Finnrick for identity, purity and quantity according to our usual process. The vials were anonymized before being sent to the testing lab.
About CertaPeptides Test Results From Finnrick
CertaPeptides 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 0 products and 2 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.
