About Peptide Bureau

Our Story

Peptide Bureau was founded out of frustration. The people who started it spent countless hours searching for reliable information about which vendors actually deliver quality products, how to use these compounds safely, and what really separates one supplier from another.

Most information online was either heavily biased toward specific vendors through affiliate relationships, overly technical without practical guidance, or simply outdated. We watched vendors come and go, quality drift from batch to batch, and customer support vary dramatically between suppliers.

So we started documenting what can actually be checked: each vendor's published certificates of analysis, independent testing records where they exist, their policies and their prices. That desk research is the foundation of Peptide Bureau, and when something could not be verified, the review says so.

Today, Peptide Bureau is a reference for anyone serious about peptide research. We earn affiliate commission from some of the vendors we review, which we disclose, and we update reviews when a vendor's documentation, testing record or prices change.

Why You Can Trust Us

Checkable Sources

Our reviews are built from evidence you can check yourself: published certificates of analysis, independent testing records, vendor policies and prices. We link the sources and say plainly when something could not be verified.

COA Transparency

We prioritize vendors who provide third-party Certificates of Analysis for their products. If a vendor won't provide testing documentation, we mark them accordingly and explain why COAs matter.

No Exclusive Deals

We never accept exclusive affiliate arrangements or special treatment from vendors in exchange for favorable reviews. Every vendor gets the same scrutiny regardless of commission structure.

Regular Updates

The peptide industry moves quickly. Vendors change hands, quality varies, new suppliers emerge. We update our reviews at least quarterly to reflect current conditions.

Our Evaluation Criteria

We evaluate every vendor using a transparent, consistent scoring system. Here's what we measure:

COA Transparency (25%)

Do they provide Certificates of Analysis? Are the testing facilities legitimate and independent? Can you verify the documents are real?

Shipping & Delivery (20%)

How fast do they ship? What are shipping options? Do they ship internationally? How reliable is delivery tracking?

Product Consistency (25%)

Do their products consistently match their claims? Have we noticed batch-to-batch variations? Do independent tests confirm quality?

Customer Service (15%)

How responsive are they to inquiries? Do they handle issues professionally? Is communication clear and helpful?

Pricing & Value (10%)

Are prices reasonable compared to quality? Do they offer bulk discounts? Is pricing transparent without hidden fees?

Longevity & Reputation (5%)

How long have they been in business? What is community sentiment about the vendor? Do they maintain consistent presence?

Who writes this

Peptide Bureau is a small independent research team. We spend our time on one thing: reading the peptide literature, tracking what vendors actually publish about their own products, and turning both into guides that answer the question you arrived with. Lars Emanuelsen edits everything that goes out.

The vendor side is part of the same job. A good protocol is worth nothing if what arrives in the vial is not what the label says, so we keep the reviews and price tables current and say plainly which sellers we would order from ourselves. We are not clinicians, we do not sell peptides, and nothing on this site is medical advice.

How the site is paid for: some outbound vendor links earn the Bureau a commission at no cost to the reader. Reviews of vendors the Bureau does not partner with carry no affiliate links. Every statement about a vendor comes from the vendor's own pages or a named, linked source, and the review says so when something could not be verified.

Corrections and questions: reply to any Bureau email or write to bureau@peptidebureau.com. Someone on the team reads it.

A note on how we are funded

Peptide Bureau is reader-supported. A portion of outbound vendor links on this site earn us a small commission at no additional cost to the reader. Rankings are set by scorecard output, not by commission rate. We have never accepted payment in exchange for placement, and we will not.
