4.2/ 5Well documented

Data coverage

100%

Coverage is the share of scored fields we hold and corroborated for American Peptides. A score built on a handful of unchecked claims and a score built on forty verified data points are not the same finding, so both numbers are always published together. How coverage is computed.

good

Strengths

  • Publishes 102 lot-specific certificates across its catalogue
  • Certificates are readable publicly, without an account
  • Testing laboratory named on certificates (Bioviridian Inc.)
  • Testing laboratory holds ISO/IEC 17025 accreditation
  • Operates under a named legal entity (American Peptides LLC)
  • Publishes a physical postal address

Weaknesses

  • No independent third-party reviews located

Regulatory & enforcement record

No adverse regulatory or enforcement action on record. We record authority actions — FDA warning letters, import alerts, seizures, criminal charges — when located. Self-reported reviews are deliberately not scored, because for this market they can be manufactured.

Recorded data pointsEvery field with its source, capture date and whether we corroborated it9 verified10 claimed0 not recordedView all →

A tag of verified means we opened the cited source and confirmed the value; published means we recorded the vendor’s own published information, taken at face value. Both count in full; only a value with no checkable source earns nothing. Fields older than 90 days are marked stale.

Discrepancy is computed as the absolute difference between labeled and assayed mass, divided by the labeled mass. A vendor-published certificate is a claim; only an independently commissioned assay is treated as corroboration.

What the research says about what American Peptides sells

A vendor’s score measures what it can demonstrate about its testing. It says nothing about whether the compounds it lists have evidence behind them — those are separate questions, and the digests above answer the second one.

How this score was calculatedEvery signal, its weight and the arithmetic — reconstructable by handrubric v1.10.0View calculation →

Each criterion is scored out of 100 over the signals we could assess, then weighted into the overall figure. Within a criterion, a signal contributes weight × merit × credit: merit is how good the recorded value is, credit is what its provenance earns — 1.00 for a value with a checkable source, 0 for a value recorded without one. A missing signal counts as a partial gap — half its weight — so a vendor that publishes what others leave blank scores higher, while a blank still costs; a value recorded without a source counts in full and earns nothing, so omitting one can never raise a score. A criterion with no data at all — track record when no independent reviews are locatable — is set aside and the remaining weights renormalised; the coverage figure, shown alongside, reports how complete the assessment is.
