The data behind TitrateLab.

Lab reports, supplier records, observed prices, research, and market changes—organized into source-linked intelligence with dates, provenance, and evidence gaps visible.

A dated, vendor-blind lab snapshot.

Compound-level purity, label-quantity, endotoxin, coverage, and missing-data summaries. Vendor and certificate identities are excluded, and compounds with fewer than 10 published records are suppressed.

What exists

Four evidence layers. Kept separate on purpose.

01

Laboratory records

Observed source data

Third-party reports from Freedom Diagnostics, Janoshik Analytical, Finnrick, public community sources, and buyer submissions. Fields can include peptide, test date, reported purity, measured quantity, endotoxin status, named vendor, source document, and verification URL.

Measured purity81,402 records
Quantity evidence65,501 records
Endotoxin evidence10,909 records
Verifiable at source98,467 records

02

Vendor and price observations

Observed + resolved data

Supplier identities, aliases, catalog rows, asking prices, vial sizes, delivery lanes, and stock states when known. Identity resolution joins spelling variants and documented aliases. Prices are dated observations, not manufacturing costs or guaranteed delivered quotes.

Supplier coverage52 pricelist suppliers
Active observations2,362 in-stock rows

03

Research and regulatory records

Primary-source index

Research papers, trial registrations, FDA records, warning letters, public legal filings, and other primary documents used in TitrateLab reporting. The source record and its date remain separate from TitrateLab's interpretation.

Market events

Curated public record

Dated evidence for vendor shutdowns, enforcement actions, group-buy failures, ownership links, and material market changes. Community reports can lead us to a story, but they remain claims until supported by a checkable record.

How to read it

Source record, resolved identity, and calculated metric are different things.

Observed

What a lab, seller, court, regulator, paper, or public record stated on a date.

Resolved

Our best-supported match between names, storefronts, aliases, and source records. Uncertain matches stay reviewable.

Derived

A TitrateLab calculation such as price per milligram, an aggregate, or a relative Trust Grade. The rule belongs in the methodology.

Use it correctly

Freshness, citation, and the evidence boundary.

Freshness is field-level

  • A test date says when the sample was tested.
  • An observed date says when we saw a price or stock state.
  • A page-modified date says when editorial copy changed.
  • None of those dates guarantees that a seller's inventory is live now.

Cite the closest source

For one lab result, cite the lab record and test date. For a TitrateLab aggregate, cite the specific page, its measured date, and the relevant method.
