Krause Analytical is a minority-owned contract laboratory in Austin, Texas, led by a principal chemist with more than 45 years of analytical-chemistry experience. Finnrick partners with the lab for independent peptide testing — every sample is analyzed on calibrated, professionally operated equipment and returned as a formal Certificate of Analysis (COA) documenting exactly what was found.

What you’ll learn
Krause Analytical runs your samples through HPLC analysis, and sends back a certificate of analysis, detailing test results. Computed through your choice of Finnrick safety standards, this sample is then declared as “passing” or “failing”, depending on the answers to three critical questions:
Identity
Is this actually what the label claims, or something else entirely?
Purity
Are there other peptides, proteins, or contaminants mixed in with your compound?
Quantity
Did you receive the amount of active ingredient you paid for, or are you dosing based on wishful thinking?
HPLC is the standard analytical method for peptide characterization, used across research institutions and commercial labs worldwide.

How Finnrick publishes results
Finnrick publishes results when we can establish sample provenance and have enough evidence that the sample represents the product sold by the named vendor. Published results include vendor and product details, helping customers evaluate the available evidence and encouraging better supply-chain decisions.
Results that do not meet these requirements are shared with the requester and kept outside the public record. Read how Finnrick decides which results to publish →
Don’t want to share sample details?
The Confidential option costs an additional $99 per sample in Custom, on top of Basic testing, any product surcharge and selected tests. Standard already includes Confidential. Results are shared with you and not published publicly.
