ClearBatch — Precision, Purity, Transparency

About ClearBatch

Peptide vendor transparency, grounded in public evidence.

What ClearBatch measures

ClearBatch monitors peptide vendor product catalogs and their publicly available Certificates of Analysis (COAs). For each tracked vendor, we measure:

  • Catalog coverage — what percentage of a vendor's current catalog has a published COA
  • Testing depth — whether COAs include HPLC purity, mass spectrometry, endotoxin testing, sterility testing, and heavy metals analysis
  • Third-party lab usage — whether testing is performed by independent, recognized labs rather than in-house
  • Verification — whether published COAs can be confirmed through the testing lab's own verification portal
  • Freshness — how recently new COAs have been published and verified

What ClearBatch does not claim

  • ClearBatch does not rank vendors by quality, price, or trustworthiness
  • ClearBatch does not guarantee the quality or safety of any product
  • ClearBatch does not verify the accuracy of the test results themselves — only whether the vendor's published documents match what the lab's portal reports
  • A "Verified" status means the vendor publishes verifiable third-party evidence — it is not an endorsement

How catalog coverage is calculated

ClearBatch tracks a vendor's current product catalog — including products that do not have a published COA. The coverage percentage is:

coverage = (products with published COA / total current catalog products) × 100

Products that are removed from the vendor's site are no longer counted toward the total. Products without COAs remain visible in the vendor detail page to show the full catalog picture.

How COA verification works

When a vendor publishes a COA from a lab that supports online verification (such as Janoshik's public task lookup or Chromate's verification portal), ClearBatch attempts to confirm the COA through that lab's system.

A successful verification means: the lab's portal confirms a matching record with consistent details (purity, date, batch number). A "mismatch" means the portal returned different data than what the vendor published. "Unverifiable" means the lab exists but the portal could not confirm the specific COA.

Labs without online verification portals are marked as "not supported." This does not mean the COA is invalid — only that automated verification is not possible.

Transparency status badges

Each vendor receives one transparency status. Precedence: Recommended > Trusted > Acceptable > Unrated.

RecommendedHand-picked by the ClearBatch team as an editorial recommendation
Trusted50% or higher COA coverage across the product catalog
AcceptableHas testing performed by at least one Tier 1, 2, or 3 recognized lab
UnratedDoes not currently meet criteria for Recommended, Trusted, or Acceptable

Vendors that have shut down are no longer shown in public listings.

Evidence and sourcing policy

Every data point on ClearBatch is traceable to a specific vendor product, COA report, or verification attempt. Public notes on vendors or labs require at least one citation.

Unsourced allegations, rumors, or editorialized opinions are never displayed publicly. If a claim cannot be cited, it remains internal until sourcing is available.

Corrections and contact

If you believe ClearBatch is displaying incorrect data about a vendor or product:

  1. Identify the specific vendor and product that appears incorrect
  2. Provide the correct information and a source (link to the vendor's COA page, lab verification URL, etc.)
  3. Reach out via email at contact@clearbatch.net or through our Discord server in the #vendor-corrections channel

We review corrections promptly and update records when the evidence supports it. Scraper configurations are adjusted when a vendor changes their site structure.
