Test Your Tesamorelin
You bought it. But did you get what you paid for?
Community testing is free for eligible samples, subject to publication requirements.
When you order Tesamorelin online, you are trusting a vendor you have likely never met, distributing the product of a manufacturer you will never hear of, handling a compound that arrives as an unlabeled vial or powder. That is a lot of trust.
Testing removes the guesswork.

What You’ll Learn
We send your sample to a commercial analytical lab for HPLC testing — free for eligible Community samples. You receive a report that answers three critical questions:
Identity
Is this actually Tesamorelin, 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.

Every add-on is layered on top of the identity, purity, and quantity analysis your Tesamorelin sample receives anyway — see everything we can test for.
We publish results. Here’s why.
Your test results are published on Finnrick with full vendor and product details. This creates accountability: when manufacturers know their work will be evaluated publicly, quality improves, and when vendors know their supply chains will be scrutinized, they choose better partners. This is not about shaming anyone — it is about building a transparent market where quality is rewarded and poor performance has consequences.
The Confidential option costs an additional $120 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.
