PeptideSuppliers.tech Explains How It Scores 400+ Peptide Manufacturers and Suppliers

WILMINGTON, Del. - Amzeal -- PeptideSuppliers.tech, a B2B directory of peptide manufacturers, CDMOs and suppliers, now lists more than 400 companies in more than 25 countries.

Why it was built

Demand for peptides has grown quickly, and so has the number of companies selling them. For buyers, a manufacturer with a GMP facility and a reseller relabeling bulk powder can look much the same online. There was no central place to compare peptide suppliers on evidence, and no shared standard for what counts as evidence.

"Buyers kept asking the same question: how do I know this supplier is real?" said a PeptideSuppliers.tech spokesperson. "We're not a regulator and we won't get every call right. But we can check what's public, show it clearly, take no commission from the suppliers we list, and refuse to let anyone pay their way to a better score."

How it works

Each listing gets a confidence score from 0 to 100, based on evidence anyone can check:

• A named company: the legal company name and address
• Certification: GMP or ISO certification from a named body
• Lab reports: COAs from a lab that ran the test itself and can confirm the result
• Regulatory record: FDA warning letters and import alerts

Scores are re-checked regularly and can go up or down.

Basic listings are free. Companies can pay for a Verified listing or a Featured placement, which buys visibility and a more detailed review. Payment never adds points, and Featured placement is only open to companies that have already passed verification. The directory has no affiliate links and earns no commission when a buyer orders from a listed supplier.

What the directory shows today

• More than 400 listed companies, including over 230 manufacturers
• Around 100 with GMP certification
• Roughly half with third-party lab testing
• Listings across North America, Europe and Asia, plus global distributors

Based on what suppliers publish, about half of listed companies show no third-party lab testing, and only about one in four show GMP certification.
