This FAQ is built for visitors using the site as a supplier-comparison and education resource. It focuses on how the directory works, how documentation is interpreted, and what the site does not claim.
The answers below are meant to be practical reference points before opening supplier listings or review pages.
The FAQ works best as an orientation page. Once a question moves into documentation, supplier methodology, or research-use-only framing, the deeper guides usually provide the necessary detail.
Use these pages for COA and testing questions that go beyond the basics.
Use these guides to understand supplier rankings, checklists, and red flags.
Use these pages for site framing, disclosures, and educational boundaries.
No. PeptideSuppliers.org is an educational directory and review resource. It does not sell peptides, process orders, or provide medical advice.
Supplier pages are compared using visible documentation, site clarity, research framing, and buyer-fit signals rather than marketing claims alone.
On this site, verified refers to a documented review of public-facing supplier information. It does not mean a supplier is medically approved or guaranteed to be the best fit for every visitor.
No. A COA is one documentation signal. It is more useful when the batch details, dates, method, and supplier page all line up clearly.
Research-use-only language is meant to describe how a supplier frames a listing. It should appear consistently across product pages, policies, and support documents.
Some suppliers mention international shipping, but availability changes. Visitors should always confirm the current shipping policy before relying on a listing.
Affiliate relationships may exist on some pages, but the site's published methodology and disclosures explain how reviews are framed and where commercial relationships are disclosed.
Suppliers can use the contact page to request a correction and provide updated documentation, policy links, or other public-facing details that should be reviewed.
Review cadence varies by page type, but supplier pages are revisited when documentation changes, categories expand, or public-facing policies materially shift.
Check the supplier's documentation, batch-testing visibility, labeling consistency, shipping language, and site-wide disclosures before relying on any product page.
