How it works
Brands are different.
So are people’s experiences.
Peptide Index brings individual brand reviews together. The reviewer’s name, experience date and relationship to the brand stay attached to their words.
What to review
Share a firsthand experience with a brand: ordering, communication, packaging, delivery, documentation or support. Include enough detail to be useful. Keep other people’s private information, medical instructions and unsupported allegations out of your review.
Before a review appears
Submissions enter a private moderation queue. We check for relevance, spam, personal information, conflicts and abusive content. Positive and negative experiences follow the same publication rules. Publication does not mean we verified the purchase, identity or every claim. Your original review is not rewritten into a testimonial.
How the rating is calculated
The customer average uses the stars on published reviews marked as customer experiences. Reviews from owners, employees, affiliates and other disclosed relationships remain labeled and do not contribute to that average. One review per email address and brand is accepted. An email address is not proof of identity or purchase. We do not seed ratings or invent reviewers.
Your public profile
Your display name, review, rating, experience date and relationship disclosure are public if approved. Your email stays private and helps us associate submissions and handle review questions. Each submission receives a separate public review profile. We do not merge profiles based on an unverified email address; display names may not be unique.
Privacy detailsOur commercial relationships
Peptide Index is operated by the team behind Peptide Guide and is part of the same commercial project as PeptideGuide and BannedSupplements. Human Peptide Biolabs and other brands identified on their pages have supply or distributor connections to the operator. These are commercial conflicts. This site is not an independent publication.
Connected brands are labeled. Their relationship does not create a rating or a verified-purchase badge. Directory highlights are editorial selections, not a ranking. Some historical purchase links may generate a commission.
Peptide research articles
Our secondary research library contains AI-assisted, selected-source summaries with original papers and safety sources. They are not brand reviews, systematic literature reviews, product testing or medically reviewed advice. Source check dates and limitations remain visible.
