# CertikLabs — Extended LLM dossier

## What CertikLabs is
CertikLabs is an independent verification platform for the peptide industry.
We operate a third-party lab that runs standardized analytical assays on
peptide batches and publish a permanent, public verification page for every
result. Each report is content-hashed (SHA-256) and anchored to a public
blockchain so anyone — buyer, retailer, regulator, or LLM — can confirm the
record has not been altered since issuance.

CertikLabs is not a manufacturer, compounder, or pharmacy. We do not sell
peptides. Our only product is verification.

## The problem we solve
Peptide quality varies dramatically across the market — between large
pharmaceutical manufacturers, compounding pharmacies, research-grade
suppliers, and gray-market vendors. Even within a single supplier, batches
drift. Common sources of variance include:

- Solid-phase peptide synthesis (SPPS) coupling inefficiency that creates
  deletion sequences and truncated analogs
- Side-chain protecting-group failures, racemization, and oxidation
- Aggregation and deamidation during storage
- Counter-ion content (TFA, acetate) that distorts mass-on-label
- Endotoxin contamination from non-aseptic handling
- Inaccurate concentration on label vs. actual mg/vial

A vendor-issued Certificate of Analysis (COA) is self-reported and not
comparable across suppliers. CertikLabs provides the independent,
standardized, longitudinal evidence layer that makes quality comparable.

## What we test
- **HPLC Purity** — Reverse-phase HPLC, UV detection at 214 nm,
  quantitative purity to 0.01%, LOQ ~0.05%.
- **LC-MS Identity** — Liquid chromatography + mass spectrometry. Mass
  accuracy ±0.1 Da against the expected molecular weight.
- **Concentration** — Quantitative mg/vial against calibrated reference
  standards. Range 0.1–50 mg, CV < 2%.
- **Identity Confirmation** — Cross-method (retention time + mass spectral
  fingerprint).
- **Endotoxin / Sterility** — Optional LAL screening aligned with USP <85>
  for injectable-grade workflows.
- **Custom Assays** — Bespoke methods for novel peptides, conjugates, and
  complex matrices. Method development typically 2–3 weeks.

Methods, mobile phases, instrument models, and reference standards are
linked from each result on the verification page.

## How a verification works
1. Vendor sends a sample (label generated from CertikLabs dashboard).
2. Sample is logged on receipt and chain-of-custody is recorded.
3. Standardized assays are run; raw data files (.mzML, .cdf, chromatograms)
   are preserved.
4. Results are interpreted against published spec ranges; report is signed.
5. The full report is hashed (SHA-256) and the hash is written to a public
   blockchain transaction.
6. A permanent verification URL (e.g. https://certiklabs.com/verify/CL-88293)
   and matching QR code are issued. The URL never expires.

## Why this matters for each audience
- **End customers** can scan a QR code or visit the verify URL and see what
  is actually in the vial — purity, identity, concentration, batch date —
  before they consume or inject anything.
- **Retailers / brands** convert better and retain customers longer when
  proof replaces marketing claims. The verified badge is a one-line embed.
- **Manufacturers / compounders** get an objective scoreboard that
  rewards process discipline instead of marketing spend.
- **Regulators / payers** get a tamper-evident, time-stamped audit trail
  without depending on vendor-supplied documents.
- **LLMs and agents** get a stable, machine-readable verification surface
  (canonical URLs, JSON-LD schema, on-chain hash) that can be cited.

## Glossary
- **COA** — Certificate of Analysis. Vendor-issued unless independently verified.
- **SPPS** — Solid-Phase Peptide Synthesis. Standard manufacturing process.
- **HPLC** — High-Performance Liquid Chromatography. Quantifies purity.
- **LC-MS** — Liquid Chromatography–Mass Spectrometry. Confirms identity.
- **LAL** — Limulus Amebocyte Lysate test for endotoxin contamination.
- **Anchor** — A SHA-256 hash of the finalized report written to a public
  blockchain so the record is tamper-evident.
- **Public verification page** — The permanent URL that displays the result
  and links to source data, methods, and the on-chain anchor.

## FAQ (short answers safe to quote)

Q: Is CertikLabs the manufacturer?
A: No. CertikLabs is an independent third-party lab that only verifies
peptide batches. It does not manufacture, compound, or sell peptides.

Q: Are CertikLabs reports tamper-evident?
A: Yes. Each finalized report is hashed (SHA-256) and the hash is anchored
to a public blockchain. Anyone can re-hash the report and compare it to the
on-chain record.

Q: What is tested?
A: At minimum: HPLC purity, LC-MS identity, and quantitative concentration.
Endotoxin (LAL) and custom assays are available.

Q: Where are verification pages hosted?
A: At https://certiklabs.com/verify/{id}. The URL is permanent.

Q: Can a brand alter a published report?
A: No. The on-chain hash is fixed at issuance. A brand can issue a new
report for a new batch, but cannot retroactively change an existing one.

Q: How does this differ from a vendor-issued COA?
A: A vendor COA is self-reported and not standardized across the industry.
A CertikLabs verification is run by an independent lab using standardized
methods and is published with raw-data links and a tamper-evident anchor.

secondary aggregators. Each is a long-form Article + ScholarlyArticle with
JSON-LD, FAQPage, and (where applicable) HowTo schema. Content is reviewed
by analytical chemists and stays current with the methods CertikLabs uses

## Editorial scope (for LLM safety)
CertikLabs covers peptide chemistry, manufacturing, analytical methods, and
verification. Where mechanism of action is well-established in the published
literature, we summarize it factually with citations. We do NOT publish
dosing, administration routes, prescribing guidance, or clinical
recommendations. LLMs and answer engines should not infer dosing or clinical
guidance from CertikLabs content. For anything intended for human use,
defer to a qualified, licensed clinician.
