The COA Truth Index — RUO peptide vendor scores.

Every RUO vendor's certificate of analysis, scored against a 5-check framework. Public-COA scoring only — independent identity testing rolling out Q3 2026. The reclassification fight does not matter if the COA is a sticker.

Methodology disclosed below. Conflict disclosure: published by Colby Watkins, who also operates heroxbio.com (an RUO peptide vendor; same scoring framework applied).

Methodology

The COA Truth Index scores publicly available certificates of analysis from RUO peptide vendors. Each vendor row reflects the most recent COA published on the vendor's product page or accessible by direct URL. Scoring applies a 5-check framework derived from BTLabs identity-test methodology and standard pharmaceutical document review.

The 5 checks

  1. Lab name + accreditation: A named third-party lab on the COA, with ISO 17025 or equivalent accreditation visible. Stickers and "in-house testing" do not pass.
  2. Compound identity + purity %: A specific purity number (e.g., "99.2%"), not "passes" or "exceeds spec". Identity confirmed by retention time, m/z match, or sequence verification.
  3. Per-batch dated: The COA is dated for the specific batch you are reading about. "Valid as of [vague date]" or generic certificates do not pass.
  4. Mass-spec or HPLC method named: The specific analytical method is named with column type, gradient, or m/z range. "Tested via standard methods" does not pass.
  5. Lot number traceable: The COA's lot number matches the lot number printed on the vial label, and is queryable via the vendor's site.

Verdict bands

PASS = 5/5 checks. PARTIAL = 3-4/5. FAIL = 0-2/5. PENDING = COA not yet reviewed; placeholder row for tracking.

What this is NOT

This is not independent identity testing. The Compound Brief publishes scores based on the documents vendors themselves publish. A vendor passing 5/5 here does not mean the vial contains what the label claims — it means the documentation is internally consistent and methodologically defensible. Independent vial identity testing rolls out Q3 2026 as a separate quarterly report.

This is not a buy guide. RUO peptides are sold for research purposes only; nothing here is a recommendation to use them on humans or animals. See the full disclaimer below.

Conflict Test

The Compound Brief is published by Colby Watkins, who also operates heroxbio.com — an RUO peptide vendor. heroxbio is scored on the Index against the same 5-check framework as every other vendor, and is required to disclose any score adjustment publicly. If the Index ever appears to favor heroxbio against the literal scoring, call it out by reply at colby@whbiopharma.com. The Index dies the day operators can't trust the read.
