About The Peptide Catalog

What We Do

The Peptide Catalog is an independent education and price comparison platform for research peptides. We publish dosing guides, benefits breakdowns, and clinical research summaries backed by peer-reviewed studies — then help you find the best price from COA-verified vendors.

We cover 50+ peptides with tools like our reconstitution calculator and ranked vendor pages that compare real prices across multiple sources.

Why We Exist

Peptide information online is fragmented. Some of it is behind paywalls. Some is marketing disguised as education. And most “reviews” are written by the vendors themselves.

We built The Peptide Catalog because we wanted one place with honest, research-backed information and transparent pricing — not sponsored content dressed up as science.

How We Make Money

Transparency matters. When you click a vendor link on our site and make a purchase, we may earn a commission. This is how we fund the site.

What we don't do: let affiliate payments influence rankings. Every vendor on our site is scored by the same algorithm:

  • Price (40%) — real per-mg cost, updated regularly
  • COA verification (30%) — third-party lab testing is required, not optional
  • Reputation (30%) — shipping reliability, customer feedback, and track record

If a vendor doesn't meet our standards, they don't appear on the site — regardless of commission rates.

Our Standards

  • COA required — every listed vendor must provide Certificates of Analysis from independent labs
  • PubMed citations — our articles reference peer-reviewed research, not forum posts or marketing claims
  • No hype — we report what the evidence says, including when it's limited or inconclusive
  • No brand names — we use generic peptide names only, keeping content focused on the compounds, not pharmaceutical marketing
  • Not medical advice — we're an educational resource. Always consult a healthcare professional before using any peptide

Who's Behind This

We're a small team of developers and researchers who got tired of sifting through bad information and inflated prices. We built the tool we wished existed — and decided to share it.
