How to Submit a Sample for Free Peptide Testing

Finnrick offers free independent testing for members of the US public who want to verify what's in their peptide samples. Submit your free test request here. 

We currently cover 15 peptides in our free testing program. Testing for additional products, or more advanced analysis, is available as a paid service — see paid testing options. 

Is free testing right for you?

The free testing program is open to anyone in the US who has purchased peptides for personal use and wants an independent test of their sample.

We accept domestic US shipments only.

If you resell peptides, the free program is not the right fit — please see our vendor services instead.

How it works 

Step 1: Submit your request 

Fill out the request form at finnrick.com/free-sample-test. If you don't have an account yet, you'll be asked to create one so we can keep in touch with you to deliver results.

Step 2: Ship your sample 

Once your request is reviewed and approved, we'll provide a shipping address. Send your sealed, unopened vial to that address. Do not open the vial.

Step 3: Lab analysis and results 

When we receive your sample, it's anonymized and sent to one of our partner labs for analysis. Results are typically available within a few weeks and will be sent to you by email as soon as we get them. Results are also published on the site.

A few things to know

 We prioritize paid test requests. We do our best to review all free requests, but paid submissions move through the queue first. During periods of high demand, free test processing may be delayed.

 We test, we don't advise. Finnrick provides analytical results only. We don't sell peptides or offer guidance on their use.

 Paid testing is also available. If your peptide isn't in our free program, or you need a more detailed analysis, paid testing is available here.
