About Peptide Vendor Reviews

Peptide Vendor Reviews publishes vendor records and analytical results for tested samples. We show the evidence and its limitations; we do not determine whether a vendor or product is safe, suitable or lawful.

Why vendor reviews need lab data

Most peptide vendor reviews are star ratings, forum anecdotes or affiliate lists. None of them tells you what an untested vial contains. A lab report describes only the sample tested.

So every review here starts with the vendor's lab record: how many independent tests exist, how many lots were filled to label, its median purity and how each product graded. Customer reviews and business details come after the evidence, not instead of it.

The full rubric is on how we grade vendors. If you're checking a shop we haven't covered, start with the vendor verification checklist.

Principles

Evidence over claims

Laboratory grades use recorded sample measurements. Shop-published certificates count at reduced weight and are identified separately. Marketing and customer ratings do not change analytical grades.

Every number has a source

Each test on a review links to the original certificate, with the lab, batch and date, so you can check us.

Bad results stay up

We don't remove or soften a result because a vendor asks, advertises or partners with us.

No grade without data

A vendor with no independent tests is shown as untested, not as safe or unsafe.

How the site makes money

Some links to vendors are affiliate links: if you buy, we may earn a commission. Partners are labelled on their reviews. Commissions do not change test results or calculated grades. Some alternative-link placements prioritize partners and are labelled separately from lab-score rankings. We don't sell peptides and don't take orders.

Who runs it

A small editorial team imports the independent lab results, grades each vendor against the published rubric and writes the reviews. Reviews are bylined to the team rather than to one person, and every number links back to its certificate.

Important information

Peptide Vendor Reviews is a free research tool, not a medical service. Nothing here is medical advice or intended to diagnose, treat, cure, or prevent disease. Consult a licensed physician for personal medical advice. Publication does not imply FDA or other regulatory approval.

We aggregate third-party lab reports but do not guarantee their authenticity or accuracy. Results describe specific samples—not every batch or product you may receive.

Our grades reflect the available reports, not an endorsement of any vendor or product or a guarantee of safety.

Peptide Vendor Reviews earns commissions on some vendor links. Partnerships and commission terms do not affect ratings, grades, or rankings.
