Peptide Vendor Research.
Evidence First.
Independent analysis of vendor documentation, testing transparency, and business practices.
What We Evaluate
Vendor Records
We examine the availability, consistency, and clarity of vendor policies, product documentation, and supporting records.
Testing Transparency
We explain what certificates of analysis and analytical reports say, what methods they reference, and what cannot be concluded from the documents alone.
Business Practices
We review publicly available information about customer support, shipping and refund policies, disclosures, and accountability.
Our Review Methodology
1. Review the Evidence
We identify which documents are available, when they were issued, which product or batch they refer to, and whether the source can be established.
2. Explain the Methods
Our educational guides explain analytical methods such as HPLC and mass spectrometry, including their uses, limitations, and the questions a report may leave unanswered.
3. Disclose Limitations
We distinguish independent verification from vendor-supplied material. We do not describe a product as independently tested unless supporting evidence justifies that statement.

Transparency Is the Standard
Our goal is to make the available evidence easier to understand—not to replace it with marketing language. We aim to disclose limitations, correct errors, and clearly identify affiliate relationships where they exist.
