Test Your Retatrutide
You bought it. But did you get what you paid for?
When you order Retatrutide (GLP-1, GIP, and GCGR agonist) online, you’re trusting a vendor you’ve likely never met, distributing the product of a manufacturer you’ll never hear of, handling a compound that arrives as an unlabeled white powder. That’s a lot of trust.
Testing removes the guesswork.
What You’ll Learn
We send your sample to a commercial analytical lab for HPLC testing. You’ll receive a report that answers three critical questions:
Identity
Is this actually Retatrutide, 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.
Optional Testing Add-Ons
For a more complete safety profile, you can add:
Endotoxin Testing
$110Detects bacterial contamination that can cause immune reactions
Heavy Metals Panel
$120Screens for lead, arsenic, cadmium, and mercury contamination
We Publish Results. Here’s Why.
Your test results will be published on the Finnrick website with full vendor and product details. This creates accountability. When manufacturers know their work will be evaluated publicly, quality improves. When vendors know their supply chains will be scrutinized, they choose better partners.
This isn’t about shaming anyone—it’s about building a transparent market where quality is rewarded and poor performance has consequences.
Prefer to test anonymously?
We understand. You can still get your sample tested for $120 without providing vendor information. You’ll receive your full report, but we won’t publish the results publicly.
We’ve already published 1602 test results of Retatrutide sourced from 128 vendors. By choosing a public test, you contribute to a growing database that helps everyone make informed decisions. Your results become part of the solution.
Tested by Commercial Labs
Finnrick partners with commercial analytical laboratories with deep experience in research chemicals testing. These aren’t hobbyist setups—they’re professional facilities with calibrated equipment, trained technicians, and documented quality control procedures.
When your sample is analyzed, you’ll receive a formal Certificate of Analysis (COA) that documents exactly what was found.
Public testing is free. Anonymous testing available for $120.
Do you distribute peptides?
Finnrick offers professional testing services for vendors who want to verify their supply chain and build trust with customers through independent quality assurance.
