Why list with us

Reach researchers where they compare.

  • Increased visibility

    Appear in the vendor directory in the Peptide Library app and on peptidelibrary.app.

  • Product & pricing exposure

    Your products and prices show up where researchers compare options for each peptide.

  • Reviews & ratings

    Researchers can review and rate your store, building trust with new customers.

  • Direct links to your store

    Every listing links straight to your store and product pages. We never sell your products.

  • Affiliate partnerships

    Tell us about your affiliate program and we’ll explore a partnership.

  • Promotional opportunities

    Offer an exclusive discount to Peptide Library users and we can feature it next to your prices.

  • International shipping visibility

    Researchers see where you ship, so international customers find you.

  • Automatic pricing updates

    Connect an API, feed or sitemap and your listed prices stay in sync with your store.

How it works

Three steps to your listing.

  1. 1

    Apply

    Tell us about your company, catalog, shipping and any affiliate or discount offers. It takes about 15 minutes, and your progress saves as you go.

  2. 2

    Review

    Our team reviews your application and may ask for changes or integration details. We never ask for passwords or API keys in the form.

  3. 3

    Go live

    Once approved, we confirm your final listing with you and publish it in the app and on the website.

What you’ll need

  • Your logo (square, at least 256 × 256 px)
  • Your website and a short company description
  • How we can read your catalog: API, feed, sitemap or product pages
  • Where you ship, and your shipping and returns policies
  • Affiliate program and discount details, if you have them
  • A partnership contact

Never enter API keys or passwords in the application. If we need them, we’ll send a secure way to connect your store after approval.

Independent by design

Listing is free. Affiliate commissions, coupons and promotions never change vendor rankings, scores or reviews. Peptide Library doesn’t sell peptides, and listing a vendor isn’t a certification of its products. How rankings work

Questions

Vendor FAQ

Anything else? Email support@peptidelibrary.app.

  • No. Listing in the Peptide Library vendor directory is free.

  • No. Vendor scores come from researcher reviews, and placement can’t be bought. Commissions, coupons and promotions never change rankings, scores or reviews. See how rankings work.

  • No. An API or product feed keeps prices most accurate, but most stores can be listed from their public product pages or product sitemap. Manual submission works too.

  • Never in the application. If an integration needs credentials, we’ll provide a secure method for connecting them after your application is approved.

  • Yes. Your answers save automatically. Sign in again any time to pick up where you left off.

  • No. We may ask about your testing practices to review your application, but Peptide Library does not certify, test or endorse any vendor’s products, and a listing is not a statement about product quality, safety or effectiveness.

  • We review applications in the order they arrive and email you as soon as there’s an update, including if we need anything else from you.
