Test Peptide Products

Independent peptide testing is the process of sending a peptide product sample to a commercial lab so the public can see measured results, not just marketing claims. In gray-market supply chains, the core problem is uncertainty: the label is often the only “spec” you can verify at the point of use.

Finnrick reduces that uncertainty by publishing peptide testing results by product, so the public can interpret what is being sold based on a large volume of consistent measurements with a transparent methodology.

Finnrick accepts a growing list of peptide products for testing. The product table above shows, for each compound:

• whether testing is Free for the public or offered for a fee
• how many test results have been published so far
• the link to register: Test my [product] sample

If you do not see a product listed, check in the “other products” menu of the sample registration form, as additional products are listed there. You can also get in touch to suggest a product for future testing.

At a high level, the peptide testing workflow is:

1. You choose a product from the list above or the “other products” menu, and register your sample.
2. You ship the sample to Finnrick’s facility.
3. The sample is sent to a commercial lab for analysis.
4. You receive a Certificate of Analysis (COA) and the results are published when public testing is selected.

For details on scoring and how Finnrick translates lab results into ratings, see the Testing and Rating Methodology.

Finnrick uses HPLC (High Performance Liquid Chromatography) as the primary analytical method for peptide purity testing and quantity verification.

In general, HPLC-based testing is used to measure:

• Identity: whether the expected active substance is present.
• Purity: how much of the sample is the expected substance compared to peptide impurities or degradation byproducts.
• Quantity / potency: how the measured amount compares to the claim (the “label claim” listed on the vial, or a vendor-published “batch claim”).

These measurements help the public compare products using consistent test methods.

A vendor-supplied Certificate of Analysis is valuable: it states the vendor’s claim regarding a product batch they are bringing to market. However, it doesn’t serve the same purpose as independent verification. The public must be able to publicly verify:

• which sample was tested,
• what claim is being evaluated,
• and how results are being interpreted and published.

A vendor-supplied COA does not allow such a verification, and should therefore be treated differently. The Finnrick approach is designed to publish results, with a fully-transparent sample collection and testing methodology, so the public can interpret data with full context.

Published test counts and product availability change as new results are published and new products are added. For the most current view, review the product listings.
