Research peptide vendors,
ranked on data — not hype.

We compare research-chemical suppliers by affordability and a Transparency Score built only from publicly verifiable independent lab data. We give you the rankings; you make the choices.

What we stand for

The signal in a noisy industry.

We translate scattered public data into clear, comparable rankings — without the clinical jargon or the sales pitch.

Radically transparent

Our rankings draw on publicly verifiable data. Every input traces back to a source you can check yourself.

Fiercely human

We present complex data plainly and matter-of-factly. A guide, not a gatekeeper — we speak side by side with you.

Uncompromisingly trustworthy

We build trust through accuracy and clean design — and a refusal to rely on hype. If the data isn't there, we don't publish a ranking.

Methodology

How the Transparency Score works.

One number, three auditable inputs. We never use vendor self-reported figures — only data that traces to a public source.

50%

Analytical

Verified independent lab data — purity and mass-spec identity — each linked to a public verification record.

30%

Operational

Publicly observable reliability signals, such as the consistency and recency of published testing and shipping disclosure.

20%

Community

Public sentiment drawn from openly available sources, aggregated neutrally — never paid or solicited.

Versioned and documented — current methodology v1.0.0. The score measures transparency and verifiability, not product quality or any health outcome.

For vendors & partners

Get represented accurately.

  • Your publicly verifiable lab data, reflected fairly in the rankings.
  • Qualified, research-focused referral traffic — with full affiliate disclosure on every outbound link.
  • Run an affiliate program (Refersion, GoAffPro, in-house)? We'll connect through it so referrals attribute to you.
  • Affiliate relationships never change how the score is computed.

For vendors — FAQ

Quick answers.

The questions vendors usually ask before setting up an affiliate connection.

Can affiliate status influence my ranking?

No. The Transparency Score is a versioned, deterministic function with public weights — affiliate relationships sit outside it entirely. Methodology is at peptideanalyzer.com/#score.

Do you take a cut on top of the affiliate commission?

No. We operate on the standard split through your existing affiliate program (or a network like Refersion / GoAffPro). Nothing additional.

Do you require exclusivity?

Never. List with as many comparison sites as you'd like.

What data do you use? Do you scrape our site?

No scraping. We only use publicly verifiable data — for analytical scoring, that means manually-collected Janoshik sample IDs with public verify URLs. Every data point has a source URL and capture date on file.

How is referral traffic attributed?

Every outbound link on Peptide Analyzer routes through an affiliate tracker (your existing program code, or a default ?ref= param if you prefer). FTC affiliate disclosure appears on every page with outbound links.

What if our Janoshik results aren't public yet?

They need to be publicly verifiable on the testing lab's portal to count toward the analytical sub-score. We're happy to walk you through making them visible — most vendors get there in a single afternoon.

Can I see what data you have on file for us?

Yes. Email hello@peptideanalyzer.com and we'll send the current data set, sources, and capture dates we hold for your vendor.

What if I dispute a ranking?

Send us the public source you'd like us to consider. If it's verifiable and we've missed it, we'll update the data and recompute. The score function itself stays unchanged unless we bump SCORE_VERSION, in which case all vendors are re-scored together and we document the change.
