Our Vendors directory is a business listing for companies in the peptide sector. It is kept separate from our evidence library and exists for outreach: helping businesses, researchers and journalists find the right contact. These rules apply to every listing.
1. Separation from research content
Directory listings appear only in the Vendors directory. Peptide profiles, blog posts and the community never link to listed companies, and a company's listing, affiliation or payment never affects what we publish about research. A listing is not an endorsement, review or recommendation, and we do not verify product quality.
2. Who may list
Lawfully operating businesses: manufacturers, suppliers and distributors, licensed compounding pharmacies, analytical and testing laboratories, and licensed clinics or telehealth providers. The person submitting must be authorized by the company. Pharmacies and clinics must hold the licenses required where they operate, and we may ask for proof. We may decline any listing.
3. What a listing may include
- Company name, logo, type, location, website and business contact details.
- Product and service category names only, without claims.
- Certifications and testing practices, shown as “self-reported” unless we have verified them.
- Shipping or processing information and social links.
- A discount code (see section 5).
4. Prohibited content
- Health, medical or therapeutic claims of any kind, including implied claims such as “healing”, “fat loss”, “anti-aging” or “recovery” wording.
- Dosing, reconstitution, administration or other human-use instructions, calculators or protocols.
- Before/after photos and images of people using products.
- Testimonials, reviews or ratings.
- Product listings, prices or “buy” links for substances, and any wording that markets “research use only” products for use in people.
- A “research use only” or “not for human consumption” label does not make a listing acceptable. In its August 2026 warning letters, FDA treated sellers' dosing guidance, dose calculators and bundled bacteriostatic water as evidence that products were intended for human use despite such labels. Listings must not include these, and we may consider a linked website's content when reviewing a listing.
- False, misleading or unverifiable statements, including claims of FDA approval or certification the company does not hold.
5. Discount codes and affiliate links
Discount codes and affiliate links are allowed on directory listings only. They are never allowed in peptide profiles, blog posts or the community, and listed companies may not ask community members to use them. Outbound links that may earn us money carry rel="sponsored".
6. Affiliated, owned and paid listings
Any listing for a company that is owned by, or connected to, the owner of The Peptide Informative, or that earns us money (through a discount code, affiliate link or payment), is labeled Affiliated and/or Sponsored on its card and profile, next to a plain-language disclosure. Payment or affiliation never buys a review, a Verified status, or any mention in profiles or blog posts.
Current affiliated listing: BioLabDirect is owned by Justin Houldson, who also operates The Peptide Informative. We may earn from purchases using its listing code, PI20.
7. Status labels
Unclaimed: added from public business information and not yet confirmed by the company. Claimed: the company has confirmed it controls the listing. Verified: we have checked the company's identity, business contact and any certification marked as verified. Affiliated: see section 6. Verification is not a quality review.
8. Reporting a listing
Anyone can report a listing using the report form or the “Report this listing” link on any profile. Listings that break this policy may be edited, suspended or removed, and repeat violations lead to permanent removal.
9. Updates and removal
Companies should keep their listings current. Each listing shows its last-updated date. Companies may ask for their listing to be corrected or removed at any time through our contact form.
10. No medical advice
Nothing in the directory is medical advice. See our medical disclaimer.
